## Description

Wet & Forget is an outdoor cleaner that eliminates black and green stains caused by moss, mold, mildew and algae without any scrubbing, power washing or bleach. Just mix 5 parts water with 1 part Wet & Forget in a pump up garden sprayer. Fully saturate a dry surface with Wet & Forget on a cool dry day and leave it. That’s it! Just wet it and forget it. Wet & Forget goes to work with the wind and rain to gently clean the surface. Green stains generally clean up within a few weeks, a few days with rainfall. Black stains or heavy stubborn stains may take 6-12 months to fully clean up. Be Patient! Wet & Forget properly cleans surfaces, so they are likely to stay clean up to 1 year or longer. Repeat application yearly or when new stains appear to maintain a clean surface. Wet & Forget contains no bleach and is safe to use on any outdoor surface including any type of deck, siding, roof, walkway, patio, brick, and cement. Gallon Concentrate makes 6-Gallons and covers 750 - 2,250 sq. ft. depending upon severity of the stain and porosity of the surface. Wet & Forget - the easy way to clean all your outdoor surfaces

Review: Best product available! No more mold - This stuff is incredible! I used several brands before I found this one, this one is the best buy a mile!! It not only removes the mold, but it keeps it from growing back for UP to year. It's easy to use, fast acting, keeps working for months. No rinsing, no scrubbing. Highly recommended ☆
Review: Works wonders on concrete! - This WnF is soooo great. A friend told me that the darkening of concrete over time is usually tiny black mold. WnF attacks that and brings your concrete bright again! Take before photos, apply, and then be patient. In 2-4 weeks you will see the result is bright white sidewalks and driveway, and very long-lasting. I regret pressure-washing my former driveway, as it removed small amounts of the surface; accelerating the concrete aging. However, WnF is not only easier, it lasts far longer than pressure-washing without removing parts of the surface. Because you need to wait weeks to see the result it is not as gratifying when applying. But know that it works; take before and after photos —or— test on one “square” of your sidewalk first. After a few weeks, that will be brighter than the adjacent squares. If you have green active growth on your stonework or shaded areas. You may notice it turn orange as the enzymes begin working. Any thick growth may later require removal, but WnF increases the length of time before growth returns. Usually several years in my experience. I use it on my concrete driveway, sidewalks, brick + mortar, and even the shaded side of my kids’ wooden playset roof. I used it on the padded portions of my boat trailer to make it look brand new, also. I am not an expert on what surfaces to avoid, but I avoid plants + grass and I allow to dry before my pets walk on it. Definitely purchase the concentrate and determine your own dilution. When I have tried the gardenhose-end variant of this WnF product, it appears less-effective. Always apply early morning or late evening so it can maximize before the sun evaporates. Also apply when you don’t think it will rain for 24 hours (turn off your sprinkler system for a day, if you have one). I hope that helps! I cannot say enough about how great this stuff works!

*by B***M on February 16, 2026*

You won't be disappointed! Just spray it on and see the difference! I didn't move and potted plants in my patio. Just spray it evenly on your patio concrete and let it dry on its own. And you will not see any green moss or algae! I sprayed my patio umbrella's too! Great product and worth the price.
