Simple Green Oxy Solve Concrete and Driveway Pressure Washer Concentrate 1 Gallon

This cleaner helps loosen dirt and release stains from concrete, which in turn reduces the amount of time and effort required to clean aggregate and concrete driveways. Since it's a non-toxic oxy-based cleaner, there's no need to pre-soak or protect nearby vegetation prior to use. This is now my go-to cleaner and I highly recommend it.

Works great for cleaning my concrete coated driveway with my Westinghouse Pressure Washer and 16" Circular Surface Cleaner/ Washer Accessory.

It does nothing to loosen dirt and grime. Totally useless.

used it on my concrete with a brush and then I power washed. I think it helped really good to use before power washing

Does a great job at cleaning the driveway. I spilled oil all over the place and had to fix it before the wife figured it out.

I really like the idea of Simple Green products being better and safer for the environment. I bought this product specifically to get rid of some oil stains on my concrete driveway. I don't have a power washer so I used the manual technique. The oil spots were actually small, but this product did not remove the stains. I was so disappointed because there are many good reviews about this product. Maybe it would work better using a power washer. I have a neighbor who told me that the original Simple Green works fairly well on driveways (but really doesn't remove oil stains). I didn't need to spend the extra money for this specific-use product. I should have tried the original Simple Green instead.

This product did not clean our driveway. All the old spots from acorns remained even with trying at full strength. Such a waste of time and money. For the tanins in acorns and leaves that are old and set in, this product will not work. This is probably why it isn't sold in my area, because it is ineffective. Bob Villa was wrong about this product. So disappointing as we needed something non toxic, non bleach.

This item doesn't clean the simplest of driveway stains. Not worth the money

Terrible solution. Please send me a refund asap. I'll never purchase the product again.

Complete waste of time and money..Did 1/2 of the driveway with the product using a pressure washer and the other 1/2 without and the product did not get the mold, algae and lichen stains out as it advertises it will.
