Nylon, which is the plastic base for many gun industry polymers, rates well against acetone. There might be other chemicals in powder blast that affect polymer, but acetone wouldn't overly concern me.

Quoted:
There is a huge difference between Safariland Break Free Power Blast vs. the Safariland Break Free CLP Cleaner Lubricate Protectant. The latter does not have acetone in it. Safariland Break Free Power Blast has acetone in it and the acetone will melt plastic and may damage Most Polymer Parts. Please read the fine print when you look at buying these gun cleaning spray cans. If you are not careful you can ruin a good handgun in a manner of minutes. Pictures of the damage? What was hurt by the spray? |

There is a plastic-safe version I believe.

And then there is non-chlorinated brake cleaner for less than $3.

Acetone is safe on Magpul polymer, wont hurt your anodized parts either even with a brass brush. I've used that method to strip rattlecanned ARs a few times now.
For general degreasing as said above non chlorinated brake cleaner kicks ass, great for a quick clean of your upper and BCG, too. In fact I get Mobil 1, brake cleaner, lithium grease and blue shop towels for dirt cheap and they work as well as any firearm specific product Ive used. The auto section is your friend. |

Just use Slip2000 products like their 725 degreaser/cleaner and you will never have to worry about harming your firearms. It also will clean much better too.

I've used Acetone to unpaint a few ARs. Colt and Magpul plastic doesn't mind it at all.

Fortunately, most guns do not have acetone sensitive plastics in them, particularly your non-Jennings and non-HighPoint type firearms from a reputable manufacturer.
So I am not surprised your non-ghetto type guns didn't disintegrate. I also use the CRC green can non-Chlorinate brake cleaner for big jobs.
I try to avoid the plastic parts when possible but don't worry if I get a bit on. It doesn't seem to affect the nylon based parts at all. I suspect you were mainly using it on your 5.45 S&W AR no? |

I soaked a standard ar15 pistol grip in a 50/50 mixture of acetone and berryman's b12 for 2 days, didn't hurt it a single bit, no softening, discoloration or anything. I still don't know if I would hose my glocks down in it, but It should be fine.

I'm glad that you said that. I used the Acetone on my Walther's PPQ M2 pistols polymer parts and was worried as the trigger was more gritty after I cleaned it with the Safariland Break Free Powder Blast. This stuff also has Toluene in it besides the Acetone. I've heard that it does NOT hurt the polymer and then some people said it does harm the Polymer. And I'm concerned. Are all polymer the same and made with Nylon? I guess the best thing to do is to try a small amount of the cleaning spray on a non conspicuous part of the polymer of concern and see if it harms the polymer in any way after a while. If there is no visible damage or harm then you can use that cleaner. I still would not let any cleaner with acetone stay in contact with the polymer or plastic parts for any length of time. I'm wondering if the trigger on my Walthers is made out of plastic and that could be the problem. The gun is polymer but some of the internal parts may be made out of plastic maybe?

Thank you for posting those MSDS Material Safety Data Sheets. Some companies don't post those or make it hard to find them for their products. I used to work in the lab safety department and had to keep an MSDS on each chemical that we used in the laboratory and had to train the chemists on the use of MSDS before they could work in the lab. Talk about trying to heard cats. LOL
They all seem to use Acetone in their formulas. I use acetone a lot in the laboratory and have ruined a few plastic parts over the last 30 years. I'ts best to test the part and verify that it's not going to melt or deform when exposed to ACETONE or other chemicals. |
