Kroil Original Penetrating Oil (Aerosol Spray-10oz Can-Single) | Penetrant for Rusted Bolts, Metal, Hinges, Chains, Moving Parts | Rust, Corrosion Inhibitor (KS102)

Great lubricant

perfect

Excellent product, pricey though

Really like Kroil in any form, the spray can is really helpful for rusty bolts abs screws.

Haven't used this in many years, back in the early '90s when working for a propane company and helping set tanks on drilling rigs in the Anadarko Basin in west-central Oklahoma. It was quite impressive when loosening rusted bolts and fittings from tanks and oil rigs, etc., and using as a preventive for further rust build-up. I've been cleaning up some old, rusted nuts and bolts in my collection of odds and ins that I have had for fifty years or more and chasing threads on the bolts and inside the nuts so they can be used when needed. I also have some very old tools that need some care so they will continue to work well, and this stuff works for that, too. It smell somewhat odd, but, like a lot of special purpose lubricants, that is to be expected.

Great product delivered in a timely mannerWonderful

This stuff works well. It has a distinctive smell, so I recommend using it in an area with ventilation.

Very good at loosening rusty nuts, bolts, screws.
