I think this will work ok haven’t had time to use it

Felt it could have worked better

Had a slight problem with one of their products they made good for it right away. Immediately two days later I received my product product. This company is a real good company. Great company. I don’t have enough. Good words to say for them.

Don’t see any difference between this product and any other. It’s just alright.

Best thing is the ease of use. Pour it right into the pressure washer and it cleans wonderfully. I use it the 5th wheel RV and on the concrete around the house. An excellent product.

I power washed my vinyl siding which hadn’t been done in a few years and it was really dirty. I sprayed the siding down with the solution and let it soak in for 15-20 minutes, then I used a 2800 PSI pressure washer to clean it off. The dirt and mold melted away. As shown in my pictures, I got a little artistic while I was cleaning.
