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 over time. 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, Good Things Take Time! 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.

I have an area of pavers by the side of my house that is in the shade almost all year so it tends to grow mold/mildew and lichens. When I apply W&F, almost immediately the mold/mildew changes color from black to brownish color, and gradually after a few weeks the brownish color goes away, too. Similarly with lichens and moss: First it changes from live green color to a dead brownish color, and then it goes away completely. This stuff is fantastic for killing "dirty" organisms like mold and mildew and also for removing most of the stains they leave behind, but it won't clean ordinary soil, grease, etc. **Q: Can I spray thiis on my back deck today, and paint the deck 4 days later without washing?** A: Wet & Forget does not work that fast. If you were to paint your deck four days after applying this product you would be wasting your money because Wet & Forget would not work at all. In order for Wet & Forget to work it must be exposed to the elements, e.g., sun and rain. I would pressure wash the patio lightly, let it dry completely and then paint or stain it. **Q: Any luck with this cleaning mildew off of painted brick?** A: Used on roof, vinyl siding, painted concrete. Found it to be better than other products that made similar claims, just use as instructed. **Q: apply wetandforget prior to restaining ?** A: I have only applied it after staining. I suggest you contact the manufactureran ask your question. ## Frequently Bought Together - Wet & Forget Moss, Mold, Mildew, & Algae Stain Remover Multi-Surface Outdoor Cleaner Concentrate, Original, 128 Fluid Ounces - Wet & Forget Outdoor Moss, Mold, Mildew, & Algae Stain Remover Multi-Surface Cleaner, Xtreme Reach Hose End with New & Improved Nozzle, 48 Fluid Ounces - Wet & Forget Shower Cleaner Spray Multi-Surface Weekly Application Requires No Scrubbing, Bleach-Free Formula, Ready to Use, Fresh Scent, 3 Months of Cleaning, 64 Fluid Ounces, 1 Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/1333057-moss-mold-mildew-and-algae-stain-remover-multi-surface-outdoor](https://www.desertcart.be/products/1333057-moss-mold-mildew-and-algae-stain-remover-multi-surface-outdoor) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-18*
