BreakFree CLP. Only chemical I've used on every gun I own for the last half century or so.
Doesn't smell. One bottle lasts forever (I've got one I bought around 1968 or so). Cleans, Lubes. Takes off carbon on revolver cylinders if I want to and use a toothbrush. Touches up scuffs on wooden grips, leather holsters.
It's simple. That's what I want. Chasing new "Wonder Lubes" would get tiring and expensive for me. I've bought a few, maybe used them once or twice. Still have most of them, opened but barely used. Sometimes I use them on hinges and gizmos around the ranch.
It just works.
