This is interesting to see all the different things people use. When I was a kid we used an old flannel shirt cut up into squares and a straightened out coat hanger as a rod. Plain old 30 weight motor oil was our lube. Maybe we would use some of that very thin petroleum stuff we fueled the lawn mower with if we needed to. Other wise just wipe out the old powder residue, wipe it down with a very little bit of oil and put it away.
I got my first real cleaning kit in about '75 when I worked at a farm store where we sold guns and ammo and shooting supplies. Yes, you could still get 'em at some hardware stores back then.
I still have that kit and the gun oil that came with it is... take a guess... just 30 weight motor oil in a little squirt bottle. You can tell by the smell.
The cleaner is a little better smelling version of Hoppes. It is Outer's gun cleaner. I still like that smell better than Hoppes.
