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

We bought this to spray our second story exterior of our house to get the green mildew off of the siding. It worked perfectly on the first application. Highly recommend.

Actually makes the dirt and algae run off the siding.

Works as stated. If you have heavy mold/mildew,will need to use multiple applications. Follow the directions, as not to waste your purchase. I would recommend you to purchase this.

Did not go well on the application on my vinyl siding. I used a power washer to even out the cleaning with little improvement.

Worked great. It turned our siding back to white again. It does have a bleach smell but it worked. My husband had me buy more to finish the house.

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

Waste of money. Does not work as advertised.

Absolutely awesome! Hooked to hose with no problems! My mobile home had not been cleaned in 3 years!! I sprayed this on one side walked away, came back less than ten min later and sprayed off! LOOKS BRAND NEW! Will definitely be buying more!
