Just as the title suggests: What's your favorite cleaner and/or lubricant to use on your PTRs? And which would you definitely recommend to avoid?
I do as well, after I scrub the chamber, I hit with a few blasts of BRAKE CLEANER to flush out loosen carbon. BREAK CLEANER evaporates after a few seconds and leaves no residue behind.For dirty hard to reach areas, I'll use a spray cleaner,
