Rated 5.0 out of 5.0 by Leigh Works Well !
I used this on a 50 year old dirty driveway and it cleaned very well. I used a 1700 PSI power washer with no problem. It takes a little longer with the lower PSI but the ZEP does all the work. I used twice the recommended amount and let it sit for about 20 minutes; It seemed easier to spray off when I waited a few minutes longer. I also used on my brick house with no problems. I just sprayed it on, let it sit for 20 minutes and off it came. The mildew, green suit just washes away. I needed more than the recommended amount because I don't think the house/driveway had ever been done before. I'm sure the recommended amount would suffice for basic maintenance though. Its worth every penny and I'd buy again.

Rated 1.0 out of 5.0 by Salsy1 Not good
I purchased this at my local Home Depot. I applied it slightly stronger than the instructions suggest with my power washer. On my concrete driveway that has not been washed in 10 years, I don't think it did an absolute thing to clean the surface. I couldn't tell any difference in the areas where I used this cleaner versus areas I did not. I would not recommend this product unless your driveway is already clean.

Rated 5.0 out of 5.0 by BigRick very strong and nice....
I used this in my pressure washer and I am very happy with it. I simply add it to a 5 gallon bucket a little more ratio than the bottle says and I am surprised how great it works. I would recommend this any day of the week.

Rated 5.0 out of 5.0 by AlisoninTX Another Quality Product from Zep - Cleaned my Concrete
Loved using this driveway pressure wash concentrate with my pressure washer. A little goes a long way - the concentrate in this bottle makes up to 20 gallons and covers up to 5000 square feet. I tried it out on a small section of the driveway and am happy with the results; it removed what I thought were permanent stains: from tree droppings, small oil stains and general dirt build up on the concrete. Will definitely use again in the spring after the trees drop their pollen again.

Rated 5.0 out of 5.0 by FLGolfer Effective cleaner, easy to use
This product is good at removing grease and dirt. We used it both for a driveway with brick pavers and for the concrete pool deck. The product is an effective cleaner for painted concrete surfaces if you are going to repaint the surface. It will dull the painted surface. Easy to mix and use in a pressure washer.

Rated 5.0 out of 5.0 by DallasGardener Worked Really Well
I used this product in hopes of lifting some old oil stains from my driveway. It did the job very well. I was afraid it might make suds like detergant and be a mess, but he sudsing was very light and rinsed away easily. This is a good product.

Rated 5.0 out of 5.0 by Cutworm Makes the Driveway Look New
I put this on my driveway last spring. My driveway was really looking bad. After using this the concrete looked new again. Great product. I also cleaned the steps and they look much better now.

It's no silver bullet. It did take quite a bit of scrubbing and pressure washing for most of the stains on my asphalt driveway and some of them are still not completely gone. I did have to pour some Dawn on the stains for better results.
