I called the guy. "Throw it away" = throw it in the tool box and forget about using it, he went back to a muzzle break.
Mister, I tell ya what !! LOLBut how do you really feel? lol.
The issue with rimfire is the wax on the bullets as that is not easily removed with traditional cleaning methods used for sealed cans.Most quality center fire cans are not user serviceable (taken apart), they do not need to be. You will never wear it out or clog it up with normal use. For a rimfire can it is pretty standard for them to be user serviced. Rimfire ammo is dirty by nature and you want to be able to take it apart and clean it. All three of my rimfire can are like this. None of my centerfire rifle rated cans are. I shoot weekly with thousands of rounds through several of them with no issues.
So what kind of can did he have and what did he shoot through it? Let us know who makes such a terrible can that even they can't get it clean.His gunsmith soaked the can in clr, used ultra sonic, did not work. More than likely, the degree of fouling is a huge issue. As his became clogged, it became less effective in noise reduction.
If he shot a bunch of rimfire through a sealed can then I could see it happening.Are we really buying the clogged can story?
I know, I was just curious if the make believe story involved a make believe muffler.Absolute garbage model..
You've spent an awful lot of time telling folks how some crowds won't know what they're talking about, without actually answering any questions about what the actual suppressor in question were that were so utterly terrible. Many, many of us shoot high volume here, so don't think you're special in that regard.New Can weight

Build-up over time is something you have to discover for yourself as there are MANY factors.
A guy that shoots 1000 rounds per day on Ground squirrels and p. dogs is going to have very different needs than a guy that hunts big game only.
I do not shoot enough to ever plug up a can, but look up a video by Jim Eagleman of Barbour Creek. He shows how to take apart a plugged can and clean it. It was plugged!!!You've spent an awful lot of time telling folks how some crowds won't know what they're talking about, without actually answering any questions about what the actual suppressor in question were that were so utterly terrible.

My 22 can comes apart every 2000 rounds or so for routine cleaning. Never had an issue, but 22 is waxy and dirty. My Omega 30 (sealed can) is about 6 years old, and has had roughly 12,000 rounds through it. When I bought it, I asked silencerco about cleaning it. They said "it shouldn't need any, but if you ever feel like it needs cleaned, do a few hard mag dumps with hot ammo and it'll burn out most of the buildup in the can".
Out of curiosity, I tried that. Suppression was still quiet, it didn't need any cleaning, but I got curious. I weighed the can before and after, then burned 50 rounds of reloaded .308 through my ar10. It lost just over 1.1 ounces, smoked like a chimney, and worked great. That was in my first year of ownership. I've never seen a need to do it again, but it's an optional way to clean it if for some reason you just have to do so.
