Easy to use

Fantastic stuff. Years ago I was working on replacing a brake caliper on my F250. The bolts were seized tight. A friend loaned me his can of Kroil and said to spray the bolts and go have a cup of coffee. When I came out to take them off I was stunned that I was able to now do it with just a socket and ratchet. Over the years I have used this on so many things but here two weeks ago I had to replace the washer/gasket cartridge on my bathroom sink. It's supposed to just slide out. Nope! The hard water had cemented it into place. I sprayed it with the Kroil and waited an hour and that thing now just slid out. Thank you for such a great product.

Great product. Needed it to break loose seized brake lines. This was the only thing that worked.
