I purchased a Gemtech GM-22 can. I have an ultrasonic cleaner inbound. Please advise me on what solvents you use with your cleaner. Also any tips on the use of the cleaner. Thank you.

Gemtech GM-22

It’s 7075 aluminum. The punchline is, don’t clean it in your ultrasonic unless you want to destroy it. Simple Green makes an aircraft grade cleaner that’s supposed to be safe for use on aluminum in ultrasonics. My experience hasn’t been that. This would have been one of those times where being a newbie, I would have benefitted you to ask first, then buy, vs buying first and then asking.

Smudge, thanks for saving my butt! I canceled the order for the ultrasonic cleaner. This forum is awesome!

I still think an ultrasonic cleaner is worth having if you're shooting suppressed, mind you. The gun you put that can on is going to get dirtier than you've probably ever seen it, but at least you won't be stripping the anodizing off your new can.

Tough can to clean. Best to pre treat with silicon oil. Clean at regular intervals-500 rounds.

My buddy has The Gemtech 22 can. Harbor Freight Soda blaster using baking soda. Makes it musg easier to clean.
