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.

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!

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

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

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

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!

Easy application but poor results. Chunks of choline tablet remaining in the bottom afterwards.

Why did you pick this product vs others?:This is the best stuff I’ve ever used. It took me longer to get my hose untangled than clean my garage!
