Is it safe around or near water?

Is it safe around or near water?
Asked by: Phyllis
I'm afraid I don't know the answer to your question. I used it on my driveway and it worked very nicely. As I mentioned in an early posting, the moss dies very quickly but, unless you make the effort the scrape off the dead moss, it will take several months for the rain and snow to eventually wash it off. Are you considering using it near a pool? I would contact the manufacturer to find out the product's safety profile regarding usage near/around water.

If you walk on it after application, does it damage what you walk on afterward ( eg. Carpet or flooring)

Asked by: Artd
After applying Wet & Forget, keep wet shoes outside until they've fully dried. Wet & Forget will not damage the surfaces you walk on after using Wet & Forget.

This label says it makes 3 gallons, but what area will that cover? Paint products list area; can that information be given for this?
Asked by: Mark
II guess it depends on how heavy the moss infestation is. I used less than 1 gallon of mix on approx 300 ft2 with moss. Product worked well and moss has not returned in 6 mo or so Note that moss does not disappear over night- it took several weeks.

Wet & Forget 0.5 gal. Moss Mold Mildew and Algae Stain Remover is rated 3.6 out of 5 by 61.

I was skeptical that this product would remove deep and not-so-deep moss/algae stains on my 23-year old vinyl siding but gave it a try. WOW! After mixing as directed and liberally applying to our house's (vertical) vinyl siding last week using a pressure sprayer nearly all moss and algae was gone following last night's rain. I only used a small amount of the 1-gallon mixture to cover a large area of siding so have a lot left over and will reapply to those few small spots where a light moss residue remains. I hope this product has a long shelf life because a little bit goes a long way at least on vinyl siding. My concern about this product leaving a residue or stain on the siding that would show where the product was / wasn't applied appears unfounded as I couldn't see a difference in the siding's color or appearance. There are a few more areas on the house's siding that need this product but are up high and require an extension ladder. Now that this product has proven itself I will reapply to the small spots on lower wall and then apply to higher spots.

Nothing seemed to happen. But....after about a day...boy, ok, this DOES work. Mix it with the right amount of water and it does the trick. It's a bit pricey but I was able to cover a lot of surface with one bottle.

Rated 1 out of 5 by from Does not work I followed application very carefully and used it on concrete deck in South Florida. Its been about 4 weeks and there is no noticeable improvement in removing the mildew stains. When I applied the product it fizzed and turned orange, and I was encouraged, but that was pretty much the end of story. The unstained areas are a little brighter, but the stained areas are still black. If it takes 4 months to work, then this product has limited use, and really should be renamed as a preventer (if in fact it does that). I also tried this product on a plastic outdoor lamp and it did nothing. Normally I clean the lamp with bleach, but this needs to been done every few months so I had great hopes that Wet and Forget would keep the lamp cleaner for longer periods. It didn't touch the mildew. I am going to experiment with the remaining material, increasing the concentration, and first cleaning with bleach and then applying, but I am not very optimistic. Its just not worth the effort to return to Home Depot, and its not their fault, they shouldn't take the hit on this product.

Rated 5 out of 5 by from Wet and Forget I have read other reviews and I am truly amazed. It works beautifully in Central Florida on shady concrete with black mold building up. I have pressure washed every year for 16 years which is a tedious chore, spending hours trying to remove the mold. I used this on alternating sections of the sidewalk to give myself the ability to make a side by side comparison in different degrees of sunlight exposure. There was no reaction when it was applied, there was a very slight odor, but there was a little tint of wet look immediately after the application. One week later there was a visible difference. Each day after that resulted in less mold and discoloration. The sidewalk brightened up after about three weeks. I have now applied the product to the other sections that I skipped. I don't know why other reviews mention chemical reactions. color changes, and odors. I can only assume that there may have been other chemicals already on the sidewalk before trying to use this which resulted in some sort of reaction and maybe is preventing it from working as intended? So far it even removed the serious mold built up around my AC unit. That was real bad. I highly recommend this but make sure this is not being used after you have already attempted to use other cleaners - just a thought. I know I had not cleaned my walkway since last spring so there was nothing to react with this.

Rated 4 out of 5 by from It will take time I used it on my roof with heavy moss growth, it browned out that most quickly, waited two months applied again where it may have not got enough. Some green was coming back. A year later most the dead brown moss is gone. I did have to hand pick some of the big area off by hand. I also used it on sidewalk that had black mold. It cleaned the sidewalk but again one application it took 9 months to be gone of the deep black, it is still gone, been 12 months. It will work just give it time and follow the instructions. I applied it with a two gallon pump sprayer.

A few stains usually appear every few months or so from the water that runs off of my patio roof onto the back of my house. I wire brushed the moss that had collected and applied Wet & Forget (about 3 weeks ago); stains are still there. I got much better results from spraying the stains with Clorox Cleanup, allowing it to soak for about 15 minutes and hosing it off. I was disappointed with the product.

Rated 5 out of 5 by from Does the job, am very pleased I applied this in the early spring 1-1/2 years ago on a stone patio and steps in a very humid, lakefront area in WV. Within a couple of months the areas were brighter and cleaner. I sprayed in the fall, and again the following spring and the patio area has never looked nicer. Great product, not as environmentally damaging as bleach, although you do have to be patient for results and remember to reapply occasionally in order to keep things looking good. I also used this on a bluestone patio at our primary residence in PA and have had the same great results.
