 Anyone use an ultrasonic cleaner to clean .22 suppressors? or, how to get the lead out of my can

Anyone used an ultrasonic cleaner on a .22 can? I have an outback II and it's starting to get pretty heavy. I've run brushes through it but I don't think it's doing anything. I searched for ultrasonic but didn't see if anyone was doing this.

I am thinking of getting a Harbor Freight cheap ultrasonic cleaner and trying it out but want to see if anyone else is doing this.

I use one on other gun parts.

as hard as it is to resist, I've stopped using it on silencers.

the ultrasonic isn't going to do much to the lead.

I would only use an ultrasonic cleaner on an all stainless steel suppressor. If your can is made out of aluminum you run the risk of ruining it. That said I use the ultrasonic cleaner on my MITE SS with great results.

What kind of US cleaner and cleaning liquid mix are you using?

Is it effective on the lead deposits?

I suggest to the OP to get a compressor and abrasive blasting setup. I got a small sandblaster rig from harbor freight for about $25 and a 10 gal compressor for the air for about $75.

IMO it's a lot easier on aluminum parts, a lot safer than using "the mix" (50/50 h2o2 & vinegar), and more effective than any US cleaner i've tried.

EDITED FOR COMPREHENSION: I see that your can is an Outback II, which IIRC is not a take-apart can. In that case, guys here have had good success with dunking their sealed cans in Kroil over a couple of nights.

The outback is an aluminum can so you won't be able to use the "dip" 50/50 vinegar and hydrogen peroxide as it will eat the al as well as the pb. Send it back to Gemtech and have them clean it or try and take it apart yourself. I have seen it posted that the endcaps are held on by red locktite. You will have a bugger of a time getting the baffles out though even if you get the caps off. I have a hard enough time with mine when I leave it for 1k rounds.

I fill up my ultrasonic cleaner to the line and add a cap full of Boretech's Rimfire Blend. I still have to use a brass brush to get the rest of the lead out but the ultrasonic cleaner does most of the work.

I have been debating on getting one of those sandblasting rigs from harbor freight also. It's faster than cleaning with brass brushes.

you don't have an outback do you? You have a can built to disassemble right?


my can is getting heavier on the front end. It's probably 2x or 3x the weight it was when I got it.
I can't figure out how to get that lead out other than send it back someday.

as he said - I remember Kel saying when you ship in an outback for fixing, they will (at your request) not locktite it together. At this point, you're probably hosed.

I saw that also. He said to request that they not seal the can. it can then be taken apart for cleaning.

I sent mine back and requested they not seal it. I have to clean it every 150-300 rounds or it gets very hard to get the baffles out. I figured I fired somewhere around 13,000-15,000 rounds before sending it in, and I could see build up of lead/carbon between the baffles by looking down them. I used mostly Federal bulk pack, but a fair amount (probably 2-3k) of Remington subsonics... some of the dirtiest 22LR I've shot yet. Fiochi is much cleaner.

I don't have an outback; I have a can made to disassemble. If I did it again I would look for a silencer that prevented the gasses touching the outer tube. It would weight more but would be a lot easier to get the baffles out. Once they are out you could bead blast or whatever. That or get a SS version that would handle the dip.

For you and the outback, if you figure you send it in every 15k rounds at a cost of $75 it is only $5 to clean every 1k rounds. $5 is worth it to me to not worry about scraping the anodizing off and the time and hassle it is to clean it out. Not only that but you probably could go longer if you wait until the silencer is no longer performing to your standards instead of just being heavier.

I use an utrasonic cleaner on my TAC65 baffles. I use a solutuin from Brownells that is safe for aluminum. I've cleaned the baffles several times and have not seen any evidence of damage.

I have a ultrasonic cleaner with the brownells cleaner, I have not tried my outback II yet, I did do my surefire and it took some of the coating off the outside, so now I am a little afraid to try my outback

I take my can apart and drop it in the ultrasonic with just plain warm water and leave it for a few hours. Water is HOT when i go back but the can is clean. If theres a big build up of lead i'll scrap it off with dental picks or careful with a razor blade. Skeptical on the sand blaster because i just got it and still learning how to use it.
