I have a gen 1 Colt/Umarex 22lr “M4” that I believe is mostly aluminum. It gets absurdly dirty, and I’ve routinely used bore cleaner/powder solvent to clean it, but recently read some suggestions that those solvents might damage aluminum parts.
Is there any truth to that? If so, any recommendations about what to use? The solvent works really well, so I’m hesitant to ditch it.
