I used 4 times the amount of this cleaner than they suggested. I followed all the other dir;ections but could hardly tell that it had done any good, even after soaking for 10 minutes and a lot, I mean a lot, of scrubbing. The bricks did not look much better than when I started. What is interesting is that I got some Bissel Pro carpet cleaner on the brick patio by accident. I didn't scrub or rinse it off but after a rain it came so clean that I was amazed. No scrubbing and this area is far, far, far better looking than where the Zep cleaner was used with hot water and some serious scrubbing.

Rated 5.0 out of 5.0 by Joshua Works great. Don't listen to other people.
As stated in the description this is for pressure washers! Other people say it doesn't work but they are hand scrubbing and not using this product as it should. I noticed a big difference when I used this stuff with my pressure washer.

I had high hopes for this driveway cleaner. After a tree removal company's truck dripped a huge amount of oil on our one year old asphalt driveway, I was determined to return it to pristine condition. Unfortunately, it did not do the trick. I think it just spread the oil around a little bit more. It did okay with some dirty spots but hardly more than what regular water would do. Save your money and pass on this stuff.

Rated 5.0 out of 5.0 by rvdvr2 A purchase that works
This product is something that is quite easy to use on smaller sized concrete surfaces such as patios, walkways and driveways. There is no need to use a high powered machine. The walkway was quite dirty from dirt, dust and debris from a neighboring tree. The cleaner worked very well on removing the stains that were caused by the red leaves and berries.

Applied exactly as directed, then stronger and stronger without any change in oil spots. Unfortunately the surrounding area bleached out to much lighter, making the spots more noticeable. Absolutely useless product and waste of money. I will take back to Home Depot and ask for a refund.
I called Zep customer service for suggestions but got a recording. I left a message but no return call!

Thought that buying a product at Home Depot would be higher quality, more profesional strength than what the local farm supply store would have. The Zep product removed nothing. I don't get much sun on my patio and there was a mildew buildup that made dark black stains. I applied a liberal amount of the product through my power sprayer and let it soak 10 minutes. I brushed it aggressively after that with a stiff push broom and applied another liberal dose. I noticed the foaming was very white with no dark discoloration. After using my power sprayer (advertized as 2400psi) it looked the same. I used about 1/4-1/2 cup of bleach on the area, brushed it aggressively again and let it set 5 minutes. The discoloration powered sprayed off easily. I'll be returning the unused ZEP Concrete cleaner.

I called Zep customer service to make sure that I used the correct solution to water ratio so I would get the best results. My problem was black mold on concrete driveway. As instructed by Zep I used the most concentrated ratio 25 oz per gallon of water. I then applied the solution with a pump sprayer and scrubbed
My problem areas with a stiff brush. After waiting approximately 10 minutes I pressure washed
