Like the title says what does everyone use for their suppressors with aluminum baffles? On Gemtech's website for their GM22 they recommend the following: What solvents should I use or avoid using for cleaning? Make certain that any solvent you choose is safe for the material your suppressor is made of. Avoid solvents that contain ammonia (Hoppes 9 and many bore cleaners) when cleaning aluminum suppressors. We also recommend against using water based cleaners in our suppressors. Our recommended cleaners: - Gunzilla: http://www.topduckproducts.com - Ed's Red (home made): Equal parts of Mineral Spirits, Acetone, Kerosene, and Automatic Transmission Fluid. If you wish to clean your suppressor you may submerge it in one of the solvents listed above. Soak it for 24-48 hours, remove and allow to drain. Once drained, blow the inside of the suppressor dry with compressed air. This cleaning can be helpful in the case of pistol suppressors that are fired "wet" to help remove any buildup of ablative grease, etc. The carbon is easy to remove, what about the buildup of lead? What's everyone's choice on lead buildup removal? PLEASE DO NOT COMMENT ON CLEANING SUPPRESSORS THAT ARE NOT MADE WITH ALUMINUM, THIS THREAD IS SPECIFIC TO A SUPPRESSOR USING ALUMINUM INTERNALS. I will be making some threaded PVC solvent soak pipes to soak the baffle stack in, and am planning on trying out Gemtech's recommendation of "Ed's Red". I realize that utilizing a plastic pick is essential in this process as well, but wanted to get everyone's pet cleaner for aluminum suppressors. Thanks in advance!
