Michael Warman is a professional gunsmith and operator of a full-service shooting range and training center near Polk City, Iowa. We asked Warman how to clean shotguns to maximize their functionality and longevity. Warman recommends two levels of cleaning: (1) a light routine cleaning after every use; (2) a serious annual cleaning to inspect and maintain the gun’s internal parts. The annual cleaning involves disassembly, and is best handled by a gunsmith. You can perform the routine cleaning, yourself, using this simple four-step procedure: Note: Put the gun in a dry indoor space when you come in from the field, and allow the gun to come completely to room temperature before you begin cleaning.
Step 1:Apply a few drops of cleaner/lubricant to a bore mop, and thoroughly swab the bore to remove moisture and powder residue. |
Step 2:Apply a few drops of cleaner/lubricant to a soft cloth. Remove the forearm and wipe the magazine tube. |
Step 3:For autoloaders, also wipe any gas pistons, valves or springs, and then reinstall them on the magazine tube. |
Step 4:Reassemble the gun and wipe all exterior metal surfaces with the lubricated cloth. |
According to Warman, there is no need to scrub the bore with bristle brushes or solvents after every use. He only cleans his shotgun bore to a “mirror shine” once a year, before putting the gun away for the off-season.
For routine cleaning, Warman’s favorite combination cleaner/lubricant is Prolix, which is biodegradable. After cleaning, store the gun in a clean, dry, ventilated safe or cabinet.
