Can you rinse off and paint over this product and if so, what's the recommended time to wait before rinsing? ( assuming rinsing is needed because paint may react to the chemicals.) Thanks
Asked by: Joel
Hello, this product is designed to spray and leave on , no rinsing. The ingredients work over time to remove and suppress the growth of mildew, mold and algae. It works very well for that purpose. They same company does make a product designed for immediate results, but I have never used

Rated 5 out of 5 by from Effective product I used this product at the specified dilution ratio and sprayed it on the house roof and the storage shed roof. Green (and very dense) moss coverage turned yellow over the following days and much of it died. A good portion came loose and washed off the roof during several rains over the following weeks. All lichen died. I didn't expect first application would kill all the moss. Second application should complete the job where some moss came back. Effectively killed moss on edge of driveway after first application.

I had a garage roof that had algae all over the roof and I sprayed on Spray and Walk and it took it all away. It took a few weeks but now my roof is nice and clean.

Rated 2 out of 5 by from Works just not fast. I tried this in place of my favorite Wet and Forget due to cost and availability. Didn't work anywhere as well but if used on lightly mildew, mossed etc area should be fine. Wet and Forget took moss 21/2-3 invhes deep on north side of tree shaded roof right off. And it removed heavy green mildew mold off pale grey siding on same side of house very well. We expected to have to use 2 applications, but 1 did very well. On Home Depot's spray and walk away, it took much longer and finalky gave up and used the Wet and forget as it was back in stock. However, on all of these products you have to throughly soak the surface to run off point - a mist or light spray won't work. On Wet and Forget, it reactivates each time it gets wet. On the heavy moss, it just completely disappeared off roof with no residue and 6+ yrs later still hasn't reappeared. The mildew on side of house though is ready for another treatment. These bio green products so much better than bleach or Brown Stuff or Brown Derby which are extremely toxic and damaging to skin, lungs, and eyes. For wet and forget I spray my plants first with plain wTer, used the product and then re-rinsed plants. No damage. For the spray and walk away product I sprayed the plants but covered them too and where exposed on edges, got burned and leaves yellowed. Was surprised - glad I covered. There are a number of green bio enzyme type products out there to remove moss, lichen, etc. i feel it is better to go with a product which will do the job at the least toxic level - so far Wet and Forget is my choice but there are a couple of other products from organic companies I may try. No matter which you use...it isnt instant.. Depending on area treating (how heavy the moss, etc), it could take from a week to month or more also depending on weather, temp, etc. it has to reactivate to keep cleaning, I believe. If they don't work for you and you are in very dry conditions, I would spray with hose once a week to reactivate. Check with customer service of product mfg or FAQs of product website for questions.

Rated 5 out of 5 by from Follow-Up to Previous Review After a couple of years, pressure washed same driveway. It didn't really need it that badly because the cleaner did such a good job of preventing the return of mildew. Decided to pressure wash the drive anyway because we were thinking of selling. After pressure washing, I applied Spray and Walk Away on most of the drive. I left a test section unsprayed, and that section has had new mildew appear. This stuff just works, if you are patient and give it time and use it properly.
