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

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 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.

I used Oxy Solve House and Siding Pressure Washing Solution to clean my siding, and it did an amazing job. It lifted dirt, grime, and mildew easily, leaving the surface spotless — now all I have to do is paint! The solution mixes well, works quickly, and the results are very satisfying. It made a big job much easier and saved me a ton of scrubbing. If you’re prepping your house for painting or just want a thorough clean, this product is highly effective and worth every penny.

Purchased this to clean the older vinyl siding on my home. Mixture in a sprayer per the directions and sprayed on the siding. Let it sit for 5 to 10 minutes and came back to spray it off. None of the dirt moved at all. I was trying to avoid having to scrub my siding but ended up having to scrub it anyways. Maybe it works great for someone with newer siding, but I was not impressed.
