Rated 5.0 out of 5.0 by Aaaaaaa Great for cleaning bathroom. Aaaaaaaaaaaaaaaaaaaaaa October 20, 2015
Rated 5.0 out of 5.0 by Works just as well as the name brand I had a toilet with heavy, heavy black deposits in it (so bad I thought for sure I'd need to replace it). Turned of water, flushed toilet then sponged out residual water. added 1/2 gallon and walked away. A few hours later, brushed it out and the bowl was sparkling. I've used the name brand before and didn't get better results. September 26, 2015
Rated 5.0 out of 5.0 by ZEP CALCIUM, LIME AND RUST REMOVER Love this Product ... Since we have alot of Calcium in our water I put some in my DishWasher to make sure the Glasses get really clean sister in Calif. told me about it... September 8, 2015
Rated 5.0 out of 5.0 by Great Product!!! I live out in the country and had really bad stains in my shower and sink from well water. This stuff worked instantly and they are now white again! I would recommend this to anybody that has rust in their shower, sinks or toilet from well water! March 2, 2012
Rated 5.0 out of 5.0 by Amazing product I live in an area which has some of the hardest water that I have ever come across. I have tried Lime Away, CLR and anything else that claims that it tackles hard water deposits with no success. It was suggested to me to try Zep so I thought it worth a try. Boy, was it worth it! I mixed it according to the directions (50/50), sprayed it and, literally, watched the sludge/deposits slide off without even scrubbing!!! Buy this product. You will not be disappointed.

Rated 5.0 out of 5.0 by Beats CLR hands down! I bought this product for the first time about a month ago. I could not believe have fast it worked to clean shower heads! It bubbled as soon as I set the shower heads in it. I used to use CLR... I never saw it bubble and I would have to leave then in for hours. I only let them soak in your product for about 15 minutes and they were done! I would never use anything else now! Great product! February 11, 2014
Rated 5.0 out of 5.0 by Boat fiberglass I have a 30 year old sailboat I got cheap. In the bilge the owner stored a rusty chain down at Toms River in the salt water in a slip for years, cause he wanted to much money being for sale for years. till Sandy came along and changed his mind. Just one gallon cleared it all up. Cept for the spot where the chain was actually laying for years. That I took my belt sander to, some fresh gel coat and my bilge is sparkling clean again, better than new. Bottom line, your not gonna take off rust that's embedded, like that rusty chain that almost became one with the boat embedded so deep for years. But you can repaint your driveway, siding or bilge to cover the stain. But this stuff is where to start. By the way, I got the boat for 20% of what he was asking and all the boats washed away at Toms River during Sandy anyway. So we both made out. May 5, 2015
Rated 5.0 out of 5.0 by <3 ZEP ZEP products are better than their name brand counter parts and more cost effective nearly 100% of the time. If ZEP has a version I choose it EVERY time versus name brand costlier choices. Try this test yourself drop a penny in ZEP and that other grey bottle stuff and you will be convinced that the superior product is ZEP. If this product, alone, is superior think of all the other ZEP alternative cleaning products and how they likely would perform as well.... I nor any of my family are employed by, own stock in, or are paid by ZEP or its affiliates in anyway. I just like to promote a good less expensive alternative to fellow consumers when possible. It must perform equal to or better than other more known name brands. May 14, 2013
