Great cleaner for my pressure washer. I love being able to use it safely and know that it is not damaging my vinyl siding, or my plants around the outside of the house. It does a really good job, and I only had to use a little to get a lot of my house cleaned. A good value for the amount you get.

Love this stuff. It has made cleaning my pool cage and papers so much easier. I found it worked better by using a scrub brush because with the solution on the pool cage. Took only minutes and the mold and dirt came right off. Wasn't coming off with just thr pressure washer. Would diffently recommend

I wish I had taken a before and after picture of our shed. We had purchased a 16x20 shed kit through a big box store and built it last year. Because we were also building a house, we were not able to put the siding on. The white siding sat almost a year outside...through a Wisconsin winter and spring. By the time we could side the shed, the siding was FILTHY. Like, mold and all kinds of weird grossness.The shed is only about 10'-15' from a designated wetland area, so I wanted something safe to use near it.To clean the vinyl siding, I did not use this product in a pressure washer. I used a spray nozzle with a dispenser, a bucket and a long-handled scrub brush. I pre-soaked the siding and then went to town with the scrub brush. It did a remarkably decent job. Better than I had expected, but I think it was a combination of the product and my elbow grease. Without mechanical agitation, I don't think this product would have worked as well, hence the 4 stars instead of 5.I would say if you need a decent cleaner near a sensitive environmental area, this would be it.

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.

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.

I haven't used anything that melts the green from the vinyl siding, and the 3100psi pressure washer seems to do all of the work, but this seemed to add some uniform cleanliness to the wall once dried. Hopefully it will give some residual anti-algae effectiveness. Ask me in a couple years.

Worked out erll

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.
