GI Bore Cleaner, oval cans
I have some of that GI bore cleaner, mine is in small oval tin cans with a screw cap in the center. I bought a case of it from the old Barnicle Warf Surplus Company many years ago. The stuff started to eat thru the cans. So I opened each can and poured it into a glass jar with a screw lid.
So i f you guys have any of that old bore cleaner, Keep a close eye on it !! Seems to eventually eat up the solder seams in the cans !!
I would imagine that will clean out lead fouling...... "Papa Jack "
