Closest thing to magic in a can
Closest thing to magic in a can. We had an old .22 receiver in the shop that no one could get the screws out of, it turned into a strength contest. One day, an old man came in and asked if he could have the receiver if he got the screws loose. Boss said yes and guy poured Kroil on receiver and said he’d be back in about half hour. 30 minutes later he removed the screws liked they were only finger tight. Been using Kroil ever since on anything rusted.

Grandpa Magic
I've been hearing about Kroil my whole professional life and for the longest time I never purchased it - what old guys said about it seemed too good to be true. I finally decided to give it a try and I swear that some times parts that seem to be stuck forever will fall apart given a single application of this product. It's great as a cleaner and can also double as an aphrodisiac. Buy it. Try it. You'll not regret it.

Kroil
Use Kroil all the time for cleaning my guns. In the bore it seem to help get it cleaner. Use it around my home and on the farm as a penetrating oil.

Great stuff!
I have been using and selling Kroil for 4 years now. I use it in all my guns and to work on locks and vehicles. It cleans up bores and rust like it was never there. I have cleaned up locks that were seized up and after setting for about 30 minutes all of the crud was running out of the lock and it was functioning properly. I also sell Kroil and customers always swear by it. I hate the fact that it keeps going up in price but what isn't these days. Just keep it away from rubber seals and plastic parts as it could dissolve these parts if left on .
