Kroil Aerokroil Penetrating Oil, 13 oz. aerosol (AEROKROIL)

This lubricant worked extremely well to help remove antique screws from a sewing machine that I am refurbishing. I bet I can come up with a lot more uses!

Amazing! Not the cheapest but beats any other brand. Highly recommended.

This blows away PB Blaster and many other products. This really does work.

I had tried several other name brand products to break free a 16 year old oxygen sensor. Even with a wrench extender to get leverage, still couldn't get the sensor out. I bought this, sprayed it on and let it sit over a few days (like I did with the other products). The day of the repair, I sprayed the sensor again and was able to get it out on the first try. I still have plenty left and will be keeping this handy for any other projects.

This stuff put any other penetrant to shame. It's the best on the market.

I sprayed it on some old gun parts, and let em sit. After multiple applications of letting it soak in, the rust is virtually gone.

Wow. When I read the reviews here and the ads on the radio I figured that this was THE miracle penetrant. Yah, it works but expected the oil to almost instantly un freeze the worst rusted fasteners and break free the nastiest corrosion. It works, but against PB Blaster, it works in just in a LITTLE less time. It does have a valve that regulates the flow of the very expensive product. $ to everything else considered? Meh.

This is the best I've ever used

One of the best penetrating oils out there. Far better than WD.

Best stuff on the market

Unbelievable

Did not work for me , Did not loosen rusted bearing

Kroil is good. This seller is not. For whatever reason they don't provide ship times (at least in my experience) and then refuse refunds. So guess what? Bad news.
