Rated 4.6 out of 5 by 18 reviewers.
Rated 5.0 out of 5.0 by Works Great! This degreaser works really well. I used it to clean a disassembled 60-year old machine tool part that was covered in old dried grease. The parts were placed in a plastic container and the degreaser was added and diluted with faucet-hot water. It soaked for two (2) hours. Most the grease dissolved and the rest was removed with a soft bristle brush. Really turned out well. Be sure to wear rubber gloves. Great product! May 15, 2015
Rated 5.0 out of 5.0 by Great product, and works like magic. Bought this 1 gal. Zep Industrial Purple Degreaser to clean the engine on my 15 year old Toyota Tacoma 4wd PU. Works fast, and cleans with little or no effort. In less than 1/2 hour my engine looks as it did at it's glory days. Two thumbs up on this great product. December 18, 2014
Rated 5.0 out of 5.0 by Great product Have to agree with with John in his review. Even cuts easily thru baked on food on a glass top stove, with no scraping. It's a must have for those extra tough jobs July 27, 2013
Rated 5.0 out of 5.0 by Super strong I do commercial kitchen exhaust cleaning and this stuff works wonders for the heavy grease that has hardened. It very strong so a 1 gallon bottle will last a long time in a residential setting. Just be very careful at full strength. Wear gloves and use in ventilated area. I love the purple. July 18, 2013
Rated 5.0 out of 5.0 by Great product that has solved our problem with build-up on our floors Great product- no horrible scent, immediately saw a difference in our floors. Much better price than my vendors could get it for. December 10, 2013
Rated 1.0 out of 5.0 by Do not use this product - waste of money - soap does better hjob I bought this product today to clean some minor oil spills on my driveway as my change my cars oil yesterday . First tried with 12oz / 1 Gallon ratio - nothing , the oil stood there. Then I tried 1:1 with water - same issue , I would see the solution was just sitting there doing nothing, I brush for 10 mins but the oil stain was only 10-20% gone. I spilled the whole bottle - the full concentrated bottle and I can still see that 60% of stain is still there, what a waste of money and time. I look laundry soap later and and it is much cleaner. This was pure waste of money ..., will never buy any ZEP product again August 17, 2013
Rated 5.0 out of 5.0 by The BEST degreaser sold to the public Our company cleans restaurant kitchen exhaust systems. This is the best degreaser we have ever used. Commercial products cost almost 10 times as much.Best for your money. Be careful it is so strong I don't recomend using it full strength. April 28, 2012
Rated 5.0 out of 5.0 by Best thing I haver ever seen to remove machinery to bare metal I'm using this product to strip the old grease, oxidized oil and layers of old dried coolant from a 50 year old machine tool for restoration. It is truly the best thing I have ever seen, and a soak in this stuff will do the job without even scrubbing the surface. It will also melt off the paint, primer, and fillers that were used under the paint, if used at full strength - which is the way I am using it. DO NOT use it for aluminum, bronze, brass. I think it will eat it, as it has Sodium Hydroxide as one of the main ingredients. I am using it on cast iron and steel, and where I can, I fully submerge the part and come back a few hours later to a perfectly stripped and clean (after washing with water) item. October 13, 2012
