TM Solution is a newer style “non-ammonia” bore cleaner from Tom Merideth, a well known stock maker and benchrest shooter. These types of solvents use sophisticated chemical cleaners to dissolve carbon and float out copper deposits. Many shooters feel carbon fouling is more of a problem in benchrest barrels than copper fouling, and this solvent addresses that concept. TM Solvent is non-hazardous, contains no ammonia, removes all oils present in the bore, and will not “eat” bronze brushes. Cleaning with TM Solvent should always be followed with a light application of a good bore oil.
