    Love this product, it really works!

  • Matt said:

    Applied the product in September on the roof and already see a big difference on the roof. Plan on reapplying on the spots that were missed in the Spring. Thanks.

    Thanks for the kind words!

  • Cindy Duke said:

    My son just applied your product to our pavers on the back porch. It looks great! My dogs had black prints all over it and they are gone. It only took 5 minutes instead of a 30 minute or more pressure washing job. Could you please tell me how long it takes to completely dry so my dogs can walk on it without making prints? Also, can I apply a sealer after this treatment?

    Thanks so much. Love the product – we’re fans!!

  • ltrayser said:

    Cindy,

    Thanks for your response! We always love to hear from our customers that use Wet & Forget! To answer your question: Once the Wet & Forget has dried on the surface, your dogs can walk on it with no problems. Even if the surface becomes wet after subsequent rains, it is still safe for pets. We recommend keeping pets and children off the surface just during the drying time after you first apply the product. You can seal the pavers as soon as you see that Wet & Forget has cleaned off the black or green growths.

    Wet & Forget will NOT interact with or affect other products such as sealers, stains, etc. However, once you put another product on top of the Wet & Forget it will not be able to continue cleaning, which is why we recommend waiting until the Wet & Forget has had a chance to clean the surface completely.

    If you have any further questions or concerns, please let us know. Thank you!

    I have an english tudor style home with imitation stucco. The ’stucco’ is actually a press-board with a textured surface to imitate stucco. The caulking is critical as I have discovered, since if allowed to get wet the material swells and gets soft. I have noticed some large areas with a blackish substance that is seeming to spread. Can I use this product? How much coverage should I expect?

  • ltrayser said:

    Hi Bob,

    Thanks for your comment. Wet & Forget is an outdoor product that can be used on real stucco as well as Dryvit and EFIS (two common types of imitation stucco). It will work on any black or green colored growths you may find on the surface (moss, mold, mildew, algae, and lichen).

    If the stain is not an organic growth such as dirt or hard water stains, Wet & Forget will not work on those types of infestations. You can expect a gallon of Wet & Forget concentrate to cover 375 to 1100 square feet once diluted. When applying on synthetic stucco, you can expect a coverage close to 375 square feet because that surface will soak up a lot of product. If you have any further questions or concerns, please let us know. Thanks!

    Hello – I live in SE Georgia, where I have applied W&F to my black concrete driveway. It has already lightened up considerably. Now I want to apply it to some teak tables & chairs in coastal Florida. This furniture has been recently cleaned w/diluted bleach, and then teak oil reapplied. It is in an outdoor covered area. I want to apply W&F to prevent mildew from returning. Can I safely do this? Great product!

  • ltrayser said:

    Lee,

    Thanks for your inquiry! Yes, you can use Wet & Forget on teak. It will not harm the surface. Wet & Forget was primarily developed to clean moss, mold, mildew and algae from outdoor surfaces. It will probably help keep these areas clean once applied longer than a bleach solution would. So yes, Wet & Forget will work for this application.

    If you have any further questions or concerns, please let us know. Thanks!

  • Ron said:

    I am about to repaint my house. I have some areas where mold is coming through the old paint. How would I use your product in this application?

    Thank you,
    Ron

  • Luke said:

    Ron,

    Thanks for writing in! Wet & Forget can only work on mold that is on top of the painted surface. If the mold is coming through the paint, this means that the mold was there prior to painting and has been sealed underneath. Wet & Forget cannot penetrate the old paint to resolve this problem.

    In your situation to remove the underlying mold you would need to remove the old paint, treat the surface with Wet & Forget, and then re-paint once the mold has been cleaned off. You can also treat the newly painted surface with Wet & Forget if you have any mold problems in the future. Please let us know if you have any other questions or concerns. Thanks!

  • Norma Cook said:

    I’ve read your web page; I’ve watched the video; but I still have questions. What if it doesn’t rain after applying? What if it’s 8-10 days after application, then dry again another 2 wks? If Mother Nature doesn’t cooperate then how does it work?

    We have our homes (condo association) all power washed every third or forth year; how would you apply up high? We would still have to hire someone to get up high – and someone to apply all over the homes as the residents don’t do this type of work themselves. So what’s the advantage to us to use your product?

    How many gallons to do an average 2300 sf home, with two stories?

    Your video showed a white painted railing – what about a railing of treated lumber?

  • Luke said:

    Norma,

    Thanks for your comment! I’ll try to answer all of your questions.

    - Wet & Forget works when it comes in contact with the wind and the rain. If you are not going to get rain for several weeks or days, that is fine. The Wet & Forget will still work when it comes in contact with rain at a later date. If you are not going to get rain for several months, then you would have to help it along by getting water on the surface every couple of weeks.

    - For larger buildings, such as condo associations, you can apply by having someone on the roof using a pump up garden sprayer or backpack sprayer. You can also use a commercial agricultural sprayer with a diaphragm pump system (commonly used for landscaping applications). Your association may already have one that they use for landscaping.

    - To cover a 2,300 square foot roof, you would need about three and a half gallons of Wet & Forget concentrate.

    - You can use Wet & Forget on any outdoor surface where you have moss, mold, mildew and algae growth, including treated lumber.

    If you have any further questions or concerns, please let us know. Thank you!

  • Barb said:

    Hi, I have some black and green algae on one wall of my stucco house. It does not get rain on it, so if I spray on the Wet & Forget then how long do I leave it before I wet it down with water? and how often after that should I wet it? thanks! Barb

  • Luke said:

    Hi Barb,

    Thanks for your inquiry. In order to use Wet & Forget in an area that is not exposed directly to rainfall you would need to be able to spray down the area with water about every week to week-and-a-half, starting one week after application. This will simulate natural rainfall. You will need to continue doing this until the mold and mildew is gone. Wet & Forget is specifically formulated for, and works best on, outdoor surfaces exposed to the elements such as wind and rain. That is why additional assistance is needed on covered outdoor surfaces. If you have any further questions or concerns, let us know. Thanks!

  • Jim Henry said:

    Can this be used on a old Truck that has Moss growing on it or a Car that sits in the shaded area all the time??

  • Luke said:

    Hi Jim,

    Thank you for writing in. We would not recommend using Wet & Forget on your car/truck to remove the moss, mold, or mildew stains. Please let us know if you have any other questions or concerns.
    Thank you!

  • Joel Peavyhouse said:

    We have used Wet & Forget on our log house, but it is risky to climb a ladder to get to the higher parts of the walls and the soffit using a pump-up sprayer. Can Wet & Forget be applied with a hose end sprayer? If so, which sprayers do you recommend that will give us the 1:5 ratio of product to water you recommend? This would allow us to reach the higher parts of our house much more safely.

  • Luke said:

    Hi Joel,
    Thanks for your writing in. Unfortunately, there is not a hose end sprayer that can get the 1:5 dilution rate needed to apply Wet & Forget. We recommend using a pump up garden sprayer where you can mix the proper dilution. For higher areas, there are backpack sprayers available. You can also use agricultural diaphragm pump sprayers to reach higher areas if you have access to them. If you have any further questions or concerns, please let us know.
    Thanks!

    What about removing tree sap from the exterior sandstone on the front of my house? Over the last 50 something years the sandstone has turned dark and stained from algae, tree sap, and I’m not sure what else. The sandstone exterior of my house is a huge fireplace chimney and wall. Will Wet and Forget work on this?

  • Luke said:

    Hi Polly,

    Wet & Forget will work great on the algae that is on your house that is made up of sandstone and brick. Wet & Forget is a gentle product that works with the outside elements (rain/wind) to remove the moss, mold, mildew, and algae stains from your surface.

    It will not remove the tree sap/dirt. If you have any further questions please let us know. Thanks!

  • Michelle said:

    I live in Southern California where we don’t get much rain. Is this still going to work? Is it safe to spray where my kids play?

  • Luke said:

    Hi Michelle,

    Thank you for writing in! Wet & Forget is designed to work with the outside elements (rain/wind) to clean your surface. Since you do not get much rain, we would recommend spraying water on the surface once a week, starting a week after your initial application. This process will stimulate the rainfall. You would need to continue doing this until the growth is gone.

    We recommend keeping people and pets off of the surface during the application of Wet & Forget and during the drying time (4-5 hours). After that, people and pets return to the surface with no issues. Please let us know if you have any other questions. Thank you!

  • David said:

    How should moss growing on Indoor/Outdoor carpeting on a porch deck be treated and will it affect the color of the carpet? Does the moss have to FIRST be removed by other means? The moss is at least a half an inch high and rooted in the threads of the carpet where dirt and moisture has accumulated just under the bottom of the banister railing.

  • Luke said:

    Hi David,

    Thank you for writing in! You can use Wet & Forget on your outdoor carpet that is exposed to the rain and wind. In extreme cases of growth, you would want to apply the Wet & Forget to the surface and then agitate the area with a brush to loosen up the growth. Once it is dry let the outside elements take care of the surface.

    Wet & Forget is a gentle product that has a pH 8 which is almost neutral and it will not affect the color of your carpet. When applying the Wet & Forget make sure that the surface is dry. After you apply the Wet & Forget to the surface you want to allow it to dry (4-5 hours) before it rains. Please let us know if you have any other questions. Thank you!

  • Jon said:

    Hi I just discovered your product.
    I don’t see any mentioning if it will harm any bushes one has around the house. Do I need to cover the bushes before spraying?
    Thank you.

  • Luke said:

    Hi Jon,
    Thanks for your question about using Wet & Forget around plants. When applying Wet & Forget to the surface, the runoff into surrounding soil will not harm plants. However, when you are spraying Wet & Forget we recommend to protect your nearby plants/grass from overspray by rinsing them down before and after you apply the Wet & Forget with water. You can also cover nearby plants during the Wet & Forget application to protect them from overspray. If you have any further questions or concerns, please let us know.
    Thanks!

    Can I use Wet & Foget on my sailboat canvass? I have a dodger & bimini (like a windshield & awning but you’re from NZ so you probably know what I’m talking about!) that are made of canvass & have isenglass (plastic) windows. Is it OK to use W&F on the canvass? Will W&F harm the plastic windows? How about overspray on the fiberglass deck of the boat? Also, your web site mentions using W&F on sails. How do you suggest we allow them to be exposed to rain, etc after application, since we normally avoid sailing in stormy conditions?

    Thanks in advance for your guidance.

  • Luke said:

    Hi Ted,

    Thanks for contacting us with your questions. Wet & Forget is safe to use on any outdoor surface where you have moss, mold or mildew. Yes, you can use it on all parts of your boat canvas, fiberglass, plastic windows, and sails. Wet & Forget has a pH of 8, which means it is a gentle product and will not harm any surface you apply it to on your boat. The normal contact with water, rain or spray from the water you are sailing in will help the Wet & Forget work. If you have any further questions or concerns, please let us know.

  • Shaun Chang said:

    Hi,

    I accidentally sprayed half bottle of wet&forget without dilution.

    Is my concrete surface going to be damaged?

    Thank you.

  • Luke said:

    Hi Shaun,

    Thanks for contacting us with your question. We always recommend following the label instructions of diluting 5:1 before applying to any outdoor surface. Since Wet & Forget is a gentle product with a pH of 8, it will not harm the concrete if applied at full strength. If you have any further questions or concerns, please let us know.
    Thank you!

  • Anne said:

    Your video is excellent, and now I would like to see the results after sitting through the winter.

  • Randy said:

    I have not yet tried Wet & Forget but from what I’ve seen & read, it looks like a good product.
    My question is, the area where I have the worst problem is the soffit under my roof overhang. It’s aluminum ventilated material, which is suppose to be white. It is now mostly black alge/moss.
    Since the area is not subject to the elements such as rain & wind, will your product do the job?

    Thanks, Randy

  • Luke said:

    Hi Randy,

    Thanks for the question! You can indeed apply Wet & Forget in your situation, but it requires some special instruction. Here’s a blog post we wrote on the subject:

    FAQ: Can I use Wet & Forget on outdoor surfaces not exposed to rain?

    Also, since your growth is black in color, you may want to read this article as well.

    FAQ: Why does it take longer to remove black mold?

    Let us know how it goes!

  • Luke said:

    Thank you, Anne! We’ll get out and record the results as soon as we can.

  • Tony said:

    Can you recommend a sprayer to use for your product that can reach to the second floor side of my house?

  • Luke said:

    Hi Tony,

    Thanks for contacting us with your question. If a pump up garden sprayer will not meet your needs, there are backpack sprayers available at your local hardware store that you can use. If you have access to a commercial agricultural sprayer, or tank sprayer with an attached motor that can reach higher areas, that will work as well. Using a power washer is not ideal, but it can be done if you dilute the Wet & Forget in a large, separate container first. Then put the hose for the incoming water source into the container of mixed solution instead of hooking it up to your water connection. This option is not the best because you will run through the Wet & Forget mixture pretty quickly as it is pulled through the pressure washer. Hiring someone to apply to the high areas of the roof is always an option as well. If you have any further questions or concerns, please let us know.

    I have a Garapa exotic wood deck. After installation it was sanded and then Rymar Exotic Forest Wood Sealer applied. The second coat of sealer was put on 4 months following the first coat as recommended. But now, 6 months later the deck has mold/mildew developing on most of the boards. I do not want to pay to have this new deck sanded down and was wondering if Wet and Forget would be a safe product for this decking material. Thanks for your help! Sally Nisley

  • Luke said:

    Hi Sally,
    Thanks for contacting us with your question. Yes, you can use Wet & Forget on any type of wood decking, including Garapa. Wet & Forget works on any surface moss, mold or mildew infestations and has a pH of 8 which means it will not harm or damage the deck. If you have any further questions or concerns, please let us know.

  • Pam said:

    Hi,

    The ceiling of our screened porch has developed a black mold. Three sides of the porch are screened, and it obviously has a wooden vaulted ceiling (my problem). Will this work on a ceiling of my porch? I am concerned because you mentioned it may need to be in contact with the elements. Thank you!

  • Luke said:

    Hi Pam,
    Thanks for contacting us with your question. You are correct, Wet & Forget does need contact with the elements (rainfall) to work properly. If you are applying to areas that are not exposed directly to the rain (covered decks, covered porches, etc.) you will need to assist the product by spraying the areas down with water once a week or once every two weeks until the mold and mildew is gone. You can use a garden hose or pump up sprayer to apply the water, you do not need a pressure washer or any special equipment. If you have further questions or concerns, please let us know.

  • Sally Nisley said:

    Thank you Luke for your response.

    It is good to know that I can clean my garapa hardwood decking with the Wet and Forget. Now my question is: Can I put another coat of protection (the stain/sealer) once I have sprayed on the Wet and Forget. How long would I have to wait? Most of these preservative products do not last over a year on the deck so you have to keep putting new coats on the deck. How would that work with your product? Sally Nisley

  • Luke said:

    Hi Sally,
    Good to hear from you again! You’ll need to wait for the growth to be complete gone from your deck’s surface prior to applying the stain and sealer. If you have any further questions or concerns, please let us know.

  • Perri said:

    Hi,
    I have concrete roofing tiles embedded with lichen. How effective is Wet & Forget on Lichen?

  • Luke said:

    Hi Perri,
    Thanks for contacting us with your question. Yes, you can use Wet & Forget to clean the lichen from your concrete roofing tiles. For lichen application, we recommend that you spray on the Wet & Forget, then go back and apply a second coat of Wet & Forget before the first coat dries. Lichen requires two applications of the Wet & Forget to clean the surface properly. Here is a link to an article with further information (Lichen and Time). If you have any further questions, please let us know.

  • Lisa said:

    I have a couple of questions
    1. I would like to use your product on Mexican fossil limestone that is in my garden. It is used in a pattern with grass towing in between in a checkerboard pattern with grass in between. I live in a florida and the stones become slick and dangerous to walk on during the summer. I am very excited about your product as it could solve so many problems for me! In a this situation, once I apply wet and forget, will I kill the grass in between? The grass is in 3″ strips between the 24″ x 12″ pavers. If I hose off the grass after applying in these small areas, will I wash off the stones? I usualy clean them by applying full strength bleach with a paint brush– a very laborious job but I don’t kill the grass this way.

    2. I like would like to use the product on oak adirondack chairs that have silvered and have a more powdery kind of growth, no algea. Will Wet and Forget harm them and will it help?

    3. I would also like to use it on the underside of a tin roof screened porch. It is south facing so its cool in the morning with the constant Florida along with the direct extreme heat above causes sweaing and the it grows mold/mildew on the “ceiling” underneth side.The post,beams and underside of the metsl roof of the porch are all
    exposed and painted white, so this staining is so hard to control. Will the product work in this area?

    I appreciate your responses and look forward to using a product that will help eliminate some of the constant maintenance I have to do, I’ll report back on the results!

  • Luke said:

    Hi Lisa,
    Thanks for contacting us with your questions. Yes, you can use Wet & Forget on your Mexican fossil limestone. We recommend covering plants while applying Wet & Forget or rinsing them with clear water before and after you apply Wet & Forget. Wet & Forget is best applied with a pump up garden sprayer which will help you control the spray during application. Apply Wet & Forget to a dry surface and make sure you do not have rain on the surface for 4-5 hours after application so that the product dries properly.

    Yes, you can use Wet & Forget on your Adirondack chairs. Wet & Forget is a gentle product with a pH of 8 and will not harm the surface. Wet & Forget works on organic growths: moss, mold, mildew and algae. It will not work on the graying effect of wood due to UV exposure over time.

    You can also use Wet & Forget on the underside of the roof on your screen porch. Wet & Forget works with the wind and rain to clean outdoor surfaces. If you will be applying to an area that is not directly exposed to the rain, we recommend watering the area down with your pump sprayer or garden hose every week or two weeks to simulate rainfall until the growth has been cleaned from the surface. If condensation and moisture naturally occurs on the surface, that will assist the Wet & Forget product as well.

    If you have any further questions or concerns, please let us know.
    Thank you!

  • Lisa said:

    Hi Luke,
    Thanks for the information. I still have questions about how to apply to the Mexican Fossil Stone because of how it is used in my Garden. The stones are 24 x 12 with a 3″-4″ border of grass all the way around each one of them. (I wish I could attach a photograph, if I send one, will you notify me at my email address?)
    Picture a tile floor made up of 24″ x 12″ tiles in a running bond pattern – pictures them “explode” or laid out to have 3″ – 4″ grout lines, except these are grass. This sort of installation is very common in Florida, particularly in driveways. Knowing how to do this would be of benefit to a lot of people!
    If I follow instructions and wet down the grass before I apply Wet and Forget- then I will inevitable wet the stones and I suppose to apply on a dry surface, correct? After application, if I try to wash/ wet the grass to wash off any Wet and Forget then I will potentially wash some of it off the stones. Any ideas?
    I have used bleach on them for the past 4 years ( since they were installed). I painted the bleach on with a large paint brush, allowed it to dry and then washed it off
    Can I apply Wet and Forget with a paint brush instead of spraying?
    Thanks again for your help!

  • Luke said:

    Hi Lisa,
    Thanks for the follow up question regarding your Mexican fossil stone patio. I understand your unique situation of having mold and mildew on stones that needs to be cleaned separated by grass areas you want to preserve. For areas where you need to control the overspray of the Wet & Forget very carefully, we would recommend applying on a calm day without much wind and keeping the nozzle of the pump up sprayer close to the stone surface when spraying. You can also take a piece of cardboard and shield the grass areas from overspray when you apply the Wet & Forget. It might be a better solution for your unique situation. If you have any further questions or concerns, please let us know.

  • mark said:

    Luke,

    Looking to use your product, everything i been reading sounds good.

    If I spray the concrete steps in front of the house and it rains is there any issues with tracking this into the house ? or if children are stepping on the front steps when its wet?

    Thank you for your reply.

    Mark

  • Luke said:

    Hi Mark,
    Thanks for contacting us with your question. We recommend keeping people and pets off of the concrete steps while you are applying Wet & Forget and during the drying time (4-5 hours after application). Once the Wet & Forget has dried, people and pets can walk on the surface, even if it gets wet from subsequent rainfall. You do not need to worry about the Wet & Forget getting on their paws and feet or being tracked into the house. If you have any further questions, please let us know.

  • Garry said:

    I’ve used Wet and Forget before on my deck and siding and loved the results. Now I want to use it again in preparation for re-staining my deck. I’d like to allow the minimal amount of time the product needs to work, though, so I can finish the staining this fall. So what I’d like to do is apply the W & F, allow a week or so, and then assist it with pressure washing before re-staining. Is that sufficient time for it to kill mold/mildew spores, etc.?
    Thanks,
    Garry

  • Andrew said:

    Hi Garry,

    Thanks for contacting us with your question. As you know, Wet & Forget is a gentle product that takes time to work. Usually, a green mold or mildew cleanup takes 3-4 weeks or less. The average time for cleanup on a black mold and mildew takes 6-8 weeks. The time-frame depends on how severe a moss, mold or mildew problem you have on the deck and how much rainfall you are getting. You can assist the Wet & Forget with a light power washing once it has been on the surface for a week or two if you want. Regardless, make sure the moss, mold and mildew has been removed from the deck before you re-stain so that you are not staining in any mold or mildew. If you have any further questions, please let us know.

  • Ginny said:

    I just saw a TV ad for your product and it looked interesting. My concrete patio is darkened (brown)from being under an oak tree. Will Wet&Forget lighten the concrete?

  • Luke said:

    Hi Ginny,
    Thanks for contacting us with your question. Wet & Forget is designed to work on organic growths such as moss, mold, mildew and algae. If you have a mold or mildew causing the browning due to concrete area being shaded by the trees, then Wet & Forget can help. If the browning is due to tree sap or other reasons, Wet & Forget will not be able to clean those stains. If you have any further questions or concerns, please let us know.

  • JimmyH said:

    I applied W&F to my cedar siding 3 wks ago to some black mold areas. I can see that it is starting to work as the black areas are now patchy and not solid. Is this the way it works and should I apply a second application for good measure? The stain is only a few years old in shady an area that does not get a lot of sun and I hated to re-stain the whole side so this works great for me.

  • Luke said:

    Hi Jimmy,

    Thanks for writing in with your question. Wet & Forget is a gentle product that takes time to work. On green colored mold and mildew growths, cleaning time takes 3-4 weeks. On black mold and mildew, it takes on average 8 weeks. The lightening you are seeing at 3 weeks is normal and a good sign that the product is starting to clean off the black mold.

    If you applied the product correctly with a pump up sprayer, and the cedar siding is exposed to the rain, you do not need to re-apply. Wet & Forget works with the rain over time to clean off the surface. If the area is not exposed to the rain, you will need to water it down on a weekly basis with your pump sprayer or garden hose to simulate natural rainfall. If you have any further questions or concerns, please let us know.

  • JimmyH said:

    Luke -

    Thank you for your response. The black mold is in an area with a large overhang so I will start to water it each week.

  • Mike said:

    Looks like a great product. Can it be applied to aluminum or vinyl siding during the winter? It’s December here in the midwest, but I’ll have a few days with temps in the mid 50’s when I can apply it. Thanks!

  • Wet and Forget said:

    Hi Mike,
    Yes, Wet & Forget can be used on any exterior surface where you have moss, mold or mildew – including vinyl and aluminum siding. All you need is an afternoon where the temperature is above 32 degrees during the application and drying time. Drying time usually takes about 4 to 5 hours on average. Once the Wet & Forget has dried, temps can dip below 32 and it will not affect the cleaning process. The best part about fall and winter application is that all the snow, wind and rain assists the cleaning process.

  • Steve R said:

    We have been using Wet & Forget for about 6 years. Living in SW Florida our tile roofs start to get moldy and dirty after about a year and half. Many have hired someone to pressure wash their roofs at a cost of at least $300. Our roof looks better then most that have had their roof pressure washed a year ago. We apply Wet& &Forget each spring just before the rainy season starts. I do not have to walk on our roof because my pump I use will reach our entire roof from a step ladder. Many know that walking on a tile roof may cause the tiles to crack and break. Fixing broken tiles can be expensive. I have recommended Wet &Forget to many others and they are extremely satisfied with the results. It is well worth the cost of this product. Just make sure you follow the directions exactly or it will not work as it should.

  • Wet and Forget said:

    Hi Steve,
    Thanks for writing in to share your story! You’re absolutely right, Wet & Forget is a great alternative to power washing. It saves you a lot of time, money and effort. Wet & Forget’s easy application leaves you time to sit back and relax.

  • Shelley said:

    Hello,

    If I use Wet & Forget on the stains on the stucco of my English Tudor, do I have to be afraid of it removing the color of the painted/stained wood decorative accent peices?

    Shelley

  • Wet and Forget (author) said:

    Hi Shelley,

    Wet & Forget will not harm the colors of painted or stained surfaces. The product is very gentle as it contains no bleach and is non acidic and non caustic. When applying to your stucco make sure to completely saturate the entire area rather than spot treatment. If you have anymore questions feel free to reply, thanks for commenting.

  • Debbie said:

    I have a small unfinished deck/porch underneath my carport. Will Wet and Forget be effective in this case?

  • Wet and Forget (author) said:

    Hi Debbie,

    Wet & Forget is totally safe to use on unfinished decks or porches. It sounds like it’s a covered surface, meaning it wouldn’t be touched by the rain. This is fine and you can still use wet & forget, you would just need to do one easy extra step. For best results, mix wet & forget 20oz per gallon in a garden pump sprayer and apply to the entire surface and apply heavy. After you apply, just leave it. Now I may be wrong because I’m not sure how your surface is set up so I’ll give you two answers. If your surface will be touched by the rain, the job is done. Overtime as it rains, the growth you applied to will breakdown and wash away. If your surface won’t get rain, give it a week and then every so often just spray the surface with water from the hose. If you have any more questions let me know. Thanks for asking.

    Hi Jeff,

    Wet & Forget only removes organic growth and the stain caused by the growth, you are fine to apply to remove the moss on your Cabot Oil Stained deck. Thanks for commenting.

    Dear Wet and Forget,

    I recently have had several trees trimmed/removed in front of my home. Now you can clearly see the mold that has been growing on my siding from the street. I am very excited to use this product so my house can stop being such a neighborhood eye-sore.

    Is there any way you can make it stop raining so I can use it? Hahaha!

    Thanks for the product! I hopefully will get to use it soon.

    We just stained our concrete patio can I use Wet & Forget to prevent stains from tree droppings especially oak trees?

  • Wet and Forget (author) said:

    Hi Kathy,

    I would wait a month or two and at the first sign of organic growth like a green algae stain, spray the surface to clean it up and keep it clean for at least a whole year. Wet & Forget won’t protect from sap or tannin but will definitely clean up any organic growth and keep the surface clean for a long while. Thanks for asking.

    Bought two gals of this W&F . This should make me12 gals . Am I right ?
    Also will it really kill the mildew ? I was told it does not kill the mildew but just cleans it temporarily . The house is
    all Cedar and has dis colored from the bottom up about two feet caused from the snow being up againaist it . Will I need to do the whole front of house or just the two feet ? I want it to look nice when finished .
    Thanks Beverly Meek.

    Hi Beverly,

    A gallon sized bottle of Wet & Forget will make 6 gallons total (1 gallon of Wet & Forget concentrate + 5 gallons of water). So you are absolutely correct to say you can make 12 gallons. Wet & Forget will completely sanitize the area and with the wind and the rain it will completely remove the growth and keep the area clean for at least a whole year if not longer. We always recommend applying to the entire surface as you want to get rid of all the airborne mold spores that cause the discoloration. For best results, completely saturate the cedar surface and leave it and let it dry. The wind and the rain will then do all the work for you. Let me know if you have any other questions. Thanks.

    I live in Michigan and plan to paint my farm barn next year. Can I apply the wet and forget in November and expect it work later this year and again in the spring? Thank you

  • Wet and Forget (author) said:

    Hi Lavern,

    If you apply Wet & Forget now, your barn will clean up over the next few months and stay mold, mildew, and algae free for the next 12 months. Most of our customers will apply once a year for a clean surface throughout all the seasons. Let us know if you have any other questions. Thanks!
