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

This stuff works, fourty years working in truck shops I’ve used about every miracle penetrating juice known to man. This stuff really does amaze and well worth the somewhat high price. By the way you don’t have to use as much so that makes it more economical

Great lubricant

perfect

Excellent product, pricey though

The advertisements for this product (Aero Kroil) would have you believing that after a few quick sprays and five minutes, you can loosen fully rusted bolts on 18-wheelers and commercial aircraft. If you believe that, you might want to try the wonderful palm tree laden estates beside the ocean in Nome, .... Alaska.I had an older Cannondale dual suspension mountain bike that I am fully restoring and needed to remove the rear swingarm for painting purposes. I applied two 8 mm hex keys into the opposing sides of the main swingarm bolt and applied about 50 N m of torque with no go. I then broke out my break bars and applied about 70 N m of force and still, ... no go. So, I decided to try me some Aero Kroil. I applied to one side and let it seep in for a full 24 hours and then did the other side for another 24 hours. I then heated the bolt up slightly with a heat gun and using my breaker bars, again applied roughly 70 N m of torque and it released. Nothing snapped, nothing broke, ... just proper release. (What had happened is that the installers at the Cannondale factory had applied blue Loctite to the the steel bolt which had become rusted due to humidity instead of the proper anti-seize.)So does Aero Kroil work? .... Yes, it does. Just don't have unrealistic expectations and allow it to fully work its chemical magic for a full 24 hours or more, and you will probably end up with good results. Four stars for me, mainly because of the ridiculous price. You would think they are making this stuff out of diamond dust mixed with platinum particulates. Ridiculous price, ... good product.

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

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.
