Used this to clean a north-facing apartment patio with lots of accumulated grime. Surfaces included white vinyl siding, a painted door, and painted concrete floor. Used a bucket and sponge to apply the cleaning solution. Also rinsed using a bucket and sponge as a garden hose was not available.Results are shown in before and after photos. The Simple Green did a good job overall, though there are some stubborn stains on the vinyl siding that are going to require follow-on work. Unsure how much better the Simple Green solution was compared to plain H2O; I didn't do a control study.It would be nice if the Simple Green was available in smaller sizes. I only used a small fraction of the one gallon jug.

4.0 out of 5 stars This Works Pretty Good on Stains - with Elbow Grease
Reviewed in the United States on November 13, 2023

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.

So I bought a power washer and I used the soap canon with this product. I did it all around my house and the stucco. I didn’t notice any difference and my stucco was dirty. It seemed that it might’ve gave it a little shade lighter, but that could’ve been the power washer doing it, well I buy this project again absolutely not if it was cheaper. Yes I would buy it but it’s not worth what I paid for.

I started using vinegar with my pressure washer but it wasn't removing all the mildew & mold. I wanted something strong that was Eco friendly. I went on Amazon & saw Oxy Solve had good review & decided to try it. So I bought some Oxy Solve & it did remove the mildew & mold of my mother's siding.
