This was the first time I've cleaned my Spectre II suppressor. No one counts rounds from a .22. This can has more than 5,000 rounds through it. This is a cautionary tale of waiting too long to clean a rimfire suppressor. The first step was to spray Sea Foam Deep Creep penetrating oil into the can. I let it sit for an hour. I then inverted the can and sprayed it again and let it soak for another hour. It was in a stainless steel bowl that I use in the garage.  Yuck!  I used my ~20 year old Harbor Freight ultrasonic cleaner. I mixed Simple Green and water at 1:1.  After dozens of 3 minute cycles and soaking for several hours, I switched to 100% Purple Power. Many more cycles were tried followed by soaking overnight.  Roger | ||

After the mild ultrasonic cleaner and Purple Power, the baffles look like much better. However, they're not good enough.  The next step is mechanical removal of debris. The next step was the Frankford Arsenal tumbler with stainless steel pins. This thing is fantastic! The old vibratory shakers and corn cob media have been outdated by this device. FYI, the drum spins at 66 RPM.  The tumbler didn't remove everything. It would have worked better if I had cleaned the suppressor sooner. This carbon gunk was very hard and difficult to remove. I used a sharp scraper to get into the crevices. The remaining seven baffles are identical. The order of assembly matters, according to SilencerCo.  Roger | |||

I finally caved and bought a bottle of Breakthrough suppressor cleaner. I haven't tried it out yet, but I've got a pistol can that has probably four or five thousand rounds through it with some ultrasonic baths in Simple Green every thousand rounds or so. It turns the jar of 1:1 black, but it doesn't get everything. Probably will try it out in there soon. That may be your best bet if the tumbler doesn't get everything to your satisfaction. That, or some other home made solution that's safe for your baffles. ______________________________________________ "If the truth shall kill them, let them die.” Endeavoring to master the subtle art of the grapefruit spoon. | |||

Prepared for the Worst, Providing the Best |
I've given up on trying to clean it every time. Heat seems to be the biggest culprit. I soak my stainless steel baffles in DOT5 brake fluid, and as long as I'm only shooting it on a rifle the crud just wipes right off, even when shooting semi-auto on the AR. But if I put it on my Ruger MkIV the short barrel allows for a lot more combustion inside the can, and all that crud just bakes right on. I set up a blasting cabinet in the garage with baking soda and soda blast the baffles. It cleans them to like-new condition, and would be an awesome solution if the crappy Harbor Freight cabinet actually kept all the powder inside, but it leaks around the seams and makes a mess everywhere, so I only do it when the buildup starts getting pretty bad. ----------------------------------------------------------- Any comments made by this poster are my own and do not reflect the views or opinions of my employer. | |||

Yes sir, that was my goal when I posted this thread. People here have given me good advice. I'm trying to return the favor and help the members of this forum. Also, even if your suppressor was recently cleaned, I recommend unscrewing the end caps and adding a dab of anti-seize to the threads. Roger | |||
