30 SECONDS 1-gallon Mold and Mildew Stain Remover Concentrated Outdoor Cleaner

Great alternative to pressure washing

This cleaner works great. It is important to be patient and give it time to work before rinsing it off with a hose, especially on concrete. It works much faster on siding or wood.

It works!!!

Powerwasher wouldn't clean my vinyl siding, but this connected to a hose works well!

Buy it.

Bought a month ago to clean my roll up awning; worked great, even found other things to use it on. 1,000,000 recommend! If there is anything that works better than this I would be shocked.

Very good product.

I bought One Step a few weeks ago and it does an amazing job. I sprayed the side of the house, sprayed on the One Step, waited approximately 10 minutes and sprayed it off. I retreated a few areas but was satisfied with the results. I did the shaded sides of the house first and as the sun moved around, I did the other shaded sides.

Careful when transporting

Haven’t used the product yet but beware that there isn’t any protective cover besides the cap. Unfortunately the cap isn’t sealed properly and product spilled in the back of my car. Hoping my carpet doesn’t get bleached out.
