Thread: Best solution to clean the fully sealed suppressor?

Here are some feedback based the experiment I did last night.

Schletek Suppressor Cleaner -> Not really useful against heavy carbon deposit.
Simple green + 2 hours of ultrasonic cleaning -> It actually works better than the solution. It shakes the carbon flakes from the deposit, some, but not all.

There are still visible carbon deposits inside of the suppressor. I guess I need to keep using the ultrasonic cleaner for a while now.
