How Long Will Polymer Handguns Last, Is Acetone A Killer?

if i use a spray cleaner, to get into the frame works, i use a synthetic safe spray. in fact, i know use that very same spray on my all metal guns when i need to.

i once read that some solvents can (in time) errode? or in a way "melt/soften" the plastics.....

i dunno, i pay too much even for my least expensive firearms to wanna be a lab test participant.

Just don’t ever use brake clean on a polymer gun

oh God no..back in my garage days, that stuff had a very high "aroma", and i'd see my helper float across the bays...

that and it's highly powerful stripping nature.

When I was working at my sheriffs dept, a deputy decided to use brake clean on his S&W polymer pistol, frame got somewhat sticky and kind of melting like, needless to say, ruined that pistol
 
I had a dashboard component crack from the heat of sun exposure, age, impact, or decomposition off gassing brittleness and distorted the vinyl covering.
In order to fix the plastic and recover the dash, I needed to know what exactly this plastic was.

Found by research it was ABS which when exposed to acetone, some black rubs off. This won’t happen with polyethylene based plastics. The dash fix was to literally melt an black ABS plumbing fitting (small chips is faster) with either acetone or methyl ethyl and making it into a paint-on slurry. Hardened back to a rock-like sandable surface after a few days.

Moral: to find out the properties of firearm parts, a dab of acetone with detect its vulnerability. Better to clean plastic anything without harsh chemical anyway.
 
Well I never use acetone for anything in my shop. I have sprayed out polymer frames with many different brands of CLP, bore solvent and light oil. No issues. I do generally just use CLP for everything except the bore though. For cleaning polymer frames I use DNA. Mine all look new still. I'm pretty sure they'll outlive me. Course I smoke a lot of cigarettes.

Annihilator, I assume brake clean you refer to is a liquid used for cleaning brake-pad dust off a car's hydraulic brake system components? I only bring it up to clarify that one of the most common gun cleaners is called Break Free CLP, which I have used on polymer with no ill effects (yet?). The 2 names are similar enough to require clarification...

Yea, brake clean for cars, not the break free CLP, also the original Gunscrubber will eat polymer, that’s why Birchewood Casey made a synthetic safe cleaner

Brake Clean is a solvent that is generally used as a parts cleaner and degreaser. I use it to clean steel before bluing. He definitely wasn't referring to Break Free.
