Kroil Original Penetrating Oil (Drip-8oz Can-Single), Penetrant for Rusted Bolts, Metal, Hinges, Chains, Moving Parts, Rust, Inhibitor (KL081)

I am 75 years old and have been using Kroil as my go to penetrant for as long as I can remember. When the situation calls for a product to attack rusted connections I go to the "orange can" on my shelf without hesitation.

I've been using this for several years. A friend introduced the product to me to help me remove screws from some of the family heirloom firearms that I had inherited. I was amazed at how the product penetrated and loosened the delicate old screws on the firearms. I also have heavy equipment and had a particularly difficult bolt to extract from one of my machines. Instead of pulling out the four foot cheater pipe (my usual method) I soaked it in Kroil over night and was able to extract it without rounding off the bolt or worse, breaking the bolt off in the hole. Now I use it on everything rusted before disassembly. I wonder if it will help lubricate my arthritic joints?
