When you get it, take it apart to learn how it disassembles and reassembles. At this time, a good pre-emptive measure is to coat the baffles and threads with lube, preferably a silicone oil. Weld Kleen, FIREClean, of good old DOT5 brake fluid all work pretty well. You'll be able to wipe most of the fouling off with a rag and the suppressor will be easier to disassemble.
Good stuff! I'll do that, and print the rest of the post out to look at when it comes out of jail.
