These are the 6 most critical steps to gun cleaning:
Step 1. Gun Cleaning
ALWAYS make sure the gun is unloaded and pointed in a safe direction!
Step 2. Gun Cleaning
Carefully take gun apart, making sure to keep track of all parts. Please reference your owners manual for detailed instructions on how to disassemble weapon. For most over/unders, when the action is closed, you remove the forestock (wooden part where your front hand goes underneath the barrel) by pulling down on the lever on the forestock. With the forestock off, you open the action of the gun and pull up and forward on the barrels (be careful not to let the barrels fall off the gun and to the ground once the action is open). You now have three distinct pieces, the receiver (stock and trigger assembly), the barrels, and the forestock. (Also, reference our gun cleaning video to follow along visually).
Step 3. Gun Cleaning
Clean your weapon with a solvent (such as Hoppe’s #9). Inside the barrels, use a bore brush or a rod with a patch with solvent applied to the patch. (preferable pushing from the breach to the front of barrels (the same direction the shot/slug travels). Then use a clean dry patch and push that patch through the barrels. Continue this alternating process using clean patches (first with solvent and then without) until the patches no longer come out dirty. Use a toothbrush with solvent to clean other metal parts of gun to remove accumulated residue/deposits/”gunk”.
Step 4. Gun Cleaning
Remove any remaining solvent from surfaces. Wipe down the firearm and all the parts to remove any residual solvent (which if left on metal can be harmful).
Step 5. Gun Cleaning
Wipe down metal parts with light coat of oil/lubricant/rust inhibitor. To protect the firearm and help it function properly, wipe down metal parts with a light coat of gun oil or lubricant such as silicone or RemLube by Remington. Use the lubricant/oil sparingly. A little goes a long way. If the storing the gun, try not to leave fingerprints on it. While the fingerprints will likely not do anything to effect the function of the gun, they can be unsightly and the oils on your skin may mar the finish of the metal.
Step 6. Gun Cleaning
Reassemble weapon and verify that it is functioning properly. Holding the receiver horizontal and with the barrels at a 45 degree angle to the ground, slide the barrels down onto/into the receiver until the “hook” at the bottom of the barrel(s) catches in the receiver. Lift up on the front of the barrels until they lock into place. Now reattach the forestock. With the small latch on the forestock open, slide the forestock into place and smoothly close the latch. Then open the breach of the gun and close it again to ensure reassembly was done correctly. All parts should move smoothly without any excess liquids/oils/etc visible on any part(s) of the gun. Do NOT use undue force on the weapon. Chances are if you have to use much (if any) muscle, you are doing something incorrectly.
