B&T recommends the use of Schletek gun care solutions. First start by capping the end of the suppressor. Pour the solution into the suppressor until it’s just below the mounting system then let it sit for 15-20 minutes. Once the time is up pour some of the solution out then cap the other end and shake the can to dislodge the larger bits of carbon build up. Now pour the rest of the solution out and rinse it out with warm water until the water coming out is clear. Next dry the can by blowing compressed air into the suppressor.
