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

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 used this on my vinyl siding. Popped it in a bottle that mixes water from my garden hose, applied a coat of this stuff, and let it sit for about 10 minutes. The pictures I uploaded are before and after photos. It didn't get everything in the first go, but for a house that has had this green stuff on it for a few years it's not bad. I also had no problem spraying it around my plants. I gave them a quick pre-spray of water before applying, and sprayed them after I rinsed the house to be safe. Overall, I'd call this a win. It's not 100%, but it's safe to use around plants and animals. I also accidentally spilled some on my garage floor and it's now the only clean spot. So that's something.

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 Is a very good product, had a bind with the Hoa, can say this got the job done better and easier than I was expecting. Had stubborn green stains on my siding that so easily came off with a light scrub. Would buy again!!! There also wasn’t a very strong scent. It is a bit on the pricier side but, you get a lot of use from a little, personally used it with my power washer and I had no issues.

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.

This stuff is amazing. Worked with only being on for 5 minutes. It was so hot outside it would dry so I could not leave it on longer. I was well impressed and highly recommend this product. I did half of the siding at a time to see the difference.

If you’re considering this product you may have reviewed the Reddits where “professional” pressure washers say this is crap for amateurs, and that the only way to effectively clean a deck is shocking it with lye or something similarly strong. This is not only extremely dangerous and damaging to the wood but also totally unnecessary. If you follow the directions on this product- apply, deck brush, wait 5 minutes, pressure wash, it works great for deck prep. It also did a great job removing film from my inflatable pool. The only additional step I took was to squeegee off the rinse water to fully remove the soil.

Purchase four-gallon bottles of this product to clean our entire house. Used the product as directed and was able to clean the house. Our issue is mostly algae on the less sunny side of the house. This product did nothing to remove the algae! After spraying it on using the foam nozzle and pouring the product into the dispenser tank, I sprayed the areas to be cleaned and let them sit for the recommended 3 to 5 minutes without allowing it to dry. When I started to power wash, nothing was coming off! I power-washed an entire side and put the product on again. Again, I power-washed it off, but it was the power sprayer that was removing the algae, not this product! Even though this cleaner was not doing anything, I continued to spray the entire home in the hopes it would prevent algae from coming back. I cleaned the whole house in June/July 2024, and today the algae is already back. This was a complete waste of money and time. I still have two unopened gallons of this product and no idea what to do with them. I would not recommend this product for cleaning your house. Again, it did nothing, and it was the pressure from the power washer that cleaned the siding. In fact, I had to take extra time and concentrate on areas to remove algae using the turbo nozzle.
