Questions about Kroil

18023 Views 17 Replies 14 Participants Last post by  Jack
A friend gave me some Kroil. I've read that it's good for getting lead and copper fouling out of the barrels of firearms. Any recommendations as to how to use it? How long should I let it sit and work before attempting to remove the lead or copper fouling? All information would be appreciated. Thank you.

Try AFT and acetone mixed together, if you need a LOT of penetrating oil cheaply.
Yes. Read about it in Machinist's Workshop, I think. A good writeup with some testing. I doubt the proportions have to be terribly exact, "some" of each ought to do....;topic=20131.0
