Tagging!
I spray my (Octane 9) baffles with MPro Cleaner & let them soak while cleaning whatever firearm was used. Then use elbow grease & Weaponshield to get them cleanish. I've yet to get them even close to as new. Silencerco video shows ultrasonic cleaner & they came out like new. I did try fireclean last time on 1-baffle & it was easier to clean. This time, expansion chamber & first 2 baffles finished with fireclean, we'll see what happens.
I have talked to people that use pure silicone oil.
1. Completely clean the baffles.
2. Heat them in the oven at 275 for about an hour.
3. Using a large glass jar or something that will allow the baffles to completely be covered, slowly put them in until it cools to room temp.
4. Let them drain on a pan.
Wipe them down and reinstall.
I have guys tell me that even wipes clean after 22lr.
I got some coming, I'll post up what happens.
