Questions about Kroil

18026 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.

I have had some success using Kroil to remove leading. I soak a loose fitting patch and liberally wet the bore and let it sit an hour or so, and then run a dry tight fitting patch through. Repeating if it unsuccessful at first. If you are successful, you will get striations of lead coming out with the patch. Kroil is a creeping lubricant not a solvent. It can get into microscopic crevaces and break the bond between the lead and metal bore of your firearm. It doesn't always work well for me, but when it does, it is quite impressive. I like Sweet's 7.62 copper solvent for removing copper fouling.
