SIMPLE GREEN Oxy Solve House and Siding Pressure Washer Cleaner - Removes Stains from Mold & Mildew on Vinyl, Aluminum, Wood, Brick, Stucco - Concentrate 1 Gal.

Great cleaner! Great price!

I initially added this to the power washer's soap tank without realizing that I also needed to swap in the "SOAP" head to get it to use soap from the mixing tank. After being a little disappointed in how clean the siding was getting, I noticed that the tank wasn't draining and swapped out the heads. Suddenly, the soap was bubbling and foaming, and the vinyl I'd already cleaned was dripping black water as the dirt came loose. I'm not saying it made it 10x cleaner or anything, but I could clearly see that the vinyl I'd already power-washed once came much cleaner with this product. It doesn't work miracles; it doesn't miraculously take all the work out of power-washing, but it does get it much cleaner than power-washing without it. Overall, it is a good product at a reasonable price. I'd buy it again.

I bought this to pressure wash my vinyl siding. I have very little mold on the house and thought I would use a product that was less caustic than some of the others. It did not hurt the pachysandra beneath several sections of the house, which I appreciate. It did an OK but not a great job on the normal grime that had accumulated. The water and sugar solution that dripped from the hummingbird feeder, it did not phase at all. The vinyl siding on my shed was moldy. I sprayed it on, waited and then had to use quite a bit of pressure to get the mold off. Last time, I just sprayed on (with a garden sprayer) Wet and Forget and the mold simply disappeared. I still would rather use this those with more caustic contents, but I wish it was more concentrated.

This product did an excellent job cleaning our siding and removing grime. It was easy to apply and worked quickly with the pressure washer. I was also happy to see that it didn’t harm any of the nearby landscaping or greenery, which was a big plus. If only it could clean up every mess in life as easily, because this stuff works impressively well. Highly recommend.

I bought this to use with my pressure washer, but I honestly couldn't tell the difference between using this soap and just using plain water. It didn't seem to have any special cleaning power or unique features. I only used it once or twice before it ended up sitting in the corner of my garage gathering dust. It was a waste of money for me. I wouldn't recommend it if you’re looking for a powerful cleaner that actually shows results.
