Rated 5 out of 5 by Excellent product Dissolves all rust off all steel parts in a matter of hours or even minutes for thin layers of rust. It pickles steel to a fantastic base, with no prep required for painting. March 31, 2014
Rated 5 out of 5 by Best Metal Etch anywhere....Period! This metal etch is by far, the best etching solution I have ever tried. I am an automotive restorer of classic muscle cars and this product blows POR-15's "Metal Ready" away as well as any other restoration suppliers metal etch which usually costs 2 - 3 times as much. It is fast and aggressive yet not destructive. I made a dip tank from one of HD's large 27 gallon plastic totes and filled it half way with 14 gallons of this product. Then I submerged 2 big block Chevy cylinder heads in it for 24 hours after they were sandblasted but had flash rusted. When I pulled them out and rinsed them off, I was amazed. Rust was gone and a nice dark phosphate coating remains after rinsing. I never thought of HD for restoration supplies but lately with this product and some of there Zep brand degreasers, my thoughts have changed. Home Depot...Please do not stop carrying this product!!! The price is great and so are the results. I'm loving it!!! September 7, 2014
Rated 5 out of 5 by Great Thin-Set Remover I bought this product to try and remove hardened (5 years) thin-set from the back of tiles I removed. I had to let them soak for 24hours but the cleaner worked to eat away the thinset and saved me from having to retile the entire floor or finding a similar tile. This product was a life saver for thinset removal. January 17, 2013
Rated 5 out of 5 by This stuff works very very well! I used this stuff to clean a steel gas tank that had rust in it. I let it sit in there for 3 days and then it was like brand new again. I'd highly recommend it for an application like this. February 16, 2013
Rated 5 out of 5 by This stuff works great..Please follow instructions and wear gloves. One step product just as advertised. I use this stuff at work all the time. Just be careful and follow safety procedures. It's toxic stuff! May 30, 2014
