Magnifies Muscle
When tackling the toughest nuts and bolts, any additional leverage helps. Kroil loosens tough rusted parts quickly, requiring less torque to loosen. Now that’s leverage!

Corrosion meets its match, as Kroil removes and prevents rust, cleans carbon deposits and lubricates rusty parts.
Breaks Down Carbon Deposits
Kroil not only breaks down rust, but also carbon deposits and other buildup that can seize metal parts.

I was skeptical at first; It is not the original can design. This stuff works better than anything out there. spray it on and let it sit. Been using this stuff for a few years now.

Great penetrating oil, but is a little expensive, otherwise I would give it 5 stars

I sprayed all the bolts on a 1972 C20 Chevy truck front bumper and they all came loose. The smell is not bad at all. I could actually see it go in to the threads on the rusty bolts. Nice to see a product live up to it's intention.
