OxiClean 1-gallon Multi-surface Concentrated Outdoor Cleaner

Works Great

Worked on some stuff not on others

I bought this to take care of some mold in our crawl space. I gotta say it did get some of it but it didnt get it as well as we were hoping. A little disappointed.

How to safely kill roof moss.

First use a push broom and break away whatever moss is loose, then mix it 1 part Oxyclean to 3 parts water. I purchased a backpack style sprayer from Harbor freight to apply it and this worked perfect. It took about a week for the green moss to turn yellow gold, It works by changing the PH factor and you don't need to rinse it off since rain will do that later.

Cleans without bleach

Great product. However, Lowes in Suffolk seems to be always out of stock when I need it.

Didn't Work for Vinyl Siding Mildew

I covered multiple walls of vinyl siding with this, let it sit for a few minutes, then pressure washed the walls. I've pressure washed these same walls many times with no soap, etc., over the years I've lived here. There simply was NO difference by adding this concentrated soap to my pressure washer's dispenser (which only sprayed at LOW velocity, not under pressure.) Because of this I do not recommend this for removing mildew or mold from siding.

Follow the directions and use a good scrub brush!

Easy to use and works great on the patio pavers!
