Rated 5.0 out of 5.0 by John Cleans better than spraying alone
Used up two bottles of this power washing my 2400 sq foot two story house. Ran out on the last few walls so we tried power washing without soaking in ZEP first. Noticeable difference. Ended up running to the Depot for another gallon to soak the last few walls.

Worked great on my log home. I have used many Zep products and have been very pleased with their performance. It works great in removing dirt, soot and grime with just a soaking and then pressure washing after about ten minutes. Couldn't be happier.

Rated 3.0 out of 5.0 by Roger Good cleaner to use with the pressure washer
We used Zep Commercial House and Siding Cleaner Concentrate in 20:1 ratio with our pressure washer and got some excellent results. It does not smell like a toxic solution and easy to work with. Over all an effective product that took care of the mold, dirt and fungus from the siding and the garage floor. It did not require any scrubbing but that may be because we were using a pressure washer.

I read up on this product and the reviews were pretty good so I bought a gallon. Seems to do a pretty good job so I bought another gallon and I feel that it will do an even better job the second time around. It was extremely hot on the first gallon and when I use the second gallon it will be much cooler and I expect even better results.

I used it with a power washer with great results! I had several years of built up black stuff on my vinyl siding and it made it look like new!! Great Stuff.

This pressure fluid was easy to use since I did't have to do anything but pour it in the pressure washer.

Rated 1.0 out of 5.0 by JC I wasted my money.
used in my pressure washer didn't notice a difference from just using a plain stream of water. Had to resort to using a stiff bristled brush and dawn dish detergent and bleach. let ti stand for ten minutes and washed off looks brand new. Don't waste you cash.
