KROILOriginal Penetrating Oil (Drip-8oz Can-Case of 4) | Penetrant for Rusted Bolts, Metal, Hinges, Chains, Moving Parts | Rust, Corrosion Inhibitor (AZKL081C4)

.....this is the best penetrating oil ever....it is EXPENSIVE, but it works and it works the best of all penetrating fluids IMO. I discovered it about 30 years ago and I have used it on and off since....is it cheap? NOPE. But it works....I highly recommend KROIL penetrating oil....life-long mechanic....aircraft and general purpose mechanic....

fantastic product worth the price triple A rating

I use this stuff in my shop and have no complaints the stuff works really well ! I gave this stuff for stocking stuffers to my like minded tinkering buddies.

This arrived in a new style can that resembles the containers that lighter fluid normally comes in. I prefer the old style can & bought from this vendor based on the picture, which is not accurate. The contents of the can seem to be the same old Kroil. It's expensive, but it works well.

I’ve used it before. Great product

The BEST Penetrating Oil you’ll ever use.

Works great

Great deal!
