Dirty firearms jam frequently, and the corrosive effects of gun powder residue can permanently mar the inside of the barrel and the mechanisms within the firing chamber. You must properly clean and maintain your gun after each use to ensure that it will work the way it should the next time you fire it. Here are some tips on how to clean your gun properly.
Only use a gun cleaning kit that is designed for the type of firearm you are cleaning.I was looking for more information and found it here. Shotgun cleaning rods and brushes will not fit into the barrel of a rifle, and pistol cleaning kits are not adequate for cleaning anything with a barrel longer than a few inches.
Before you begin, make sure that the weapon you are cleaning is unloaded, and the firing chamber is empty.
Working in a well-lit area, start by running the cleaning rod through the barrel with the brush attachment. Use barrel-cleaning fluid to help remove powder and lead residue.
Remove the brush attachment, and replace it with the cloth-holder attachment. Insert a new gun-cleaning cloth into the attachment, and work it back and forth to remove the cleaning fluid and any loosened debris.
Replace the cleaning cloth with a new one, and add some gun oil to it. Work it down the barrel until the inside is sufficiently coated with oil.
Do not forget to clean and lubricate the firing mechanism.
Add some gun oil with a clean cloth, and lightly coat the metal exterior of the gun with it.
