RMR House and Siding Wash - Commercial-Grade Outdoor Stain Remover for Mold, Mildew, and Algae, 64 Ounce Bottle With Hose-End Adapter

This stuff worked great! I even used it on my concrete patio and it took all the dirt and old grease stains off with no problem. Great for siding, storm doors and patio furniture as well.

Works great! My house was covered with heavy green mildew and this removed it on the first go, I need to buy more to finish the house but this was a very easy application!

This product worked better than any others I used when I pressure washed house siding . With RMR I hooked to house water followed directions sprayed on house north side and let it stay on there 5 minutes are more then sprayed clean water and it all washed away no green agae or mold on siding anymore just Gone

Haven't used it yet but it did leak in the delivery box all over and was wet when I received it.

Product did not work as good as advertised, but did work with a little scrubbing.

Don’t waste your money. It barely did two garage doors. Mostly just bleach.

product was everything it said! have to get two more bottles for the rest of the house. my gray siding was black it took off 99 percent of it. but it was bad. need more for deck. very satisfied with the ease of usage didn’t disappoint at all worth the money. recommend highly

Must be very careful to not get on your clothes, as you spray it comes back onto your clothes and make tiny little bleach spots. This is the best stuff I have ever used on my would outside on the house and my siding to get rid of mold. BUT be very careful, it can also kill your plants and flowers outside when spraying. Make sure to try and cover them all up. Would recommend for a outside mold problem
