When you get a new air gun you should clean the barrel because most manufacturers put grease or preservative in the barrel so it does not rust in shipment. After that you should only
clean the barrel when there is a problem with accuracy - not after every firing.Pure silicone oil is very good for cleaning your air gun barrel and lubricating the rest of the air gun, do not use cleaning fluids meant for regular firearms, they will ruin the seals in your air gun.
One of the most important things about cleaning an airgun barrel -- you
rarely need to clean it. In field target shooting where many people shoot 10,000 to 20,000 pellets per year, the general consensus seems to be to clean
only when accuracy seems to have degraded.
Most Airgun barrels are made from high grade soft steel.
High grade soft
steel wears faster than high grade hammer forged steel used in firearms.
IZH Baikal air guns are made in the same factory that makes the famous AK47 military rile and they have the much better hammer forged barrels just like a conventional firearm.Use a brush that is softer than the barrel
Use a brush made of a material that's softer than the barrel of your
airgun. For steel barrels, a brass brush is OK but nylon brushes are preferred, In a Benjamin brass
barrel only use a nylon brush.Felt cleaning pellets
Felt cleaning pellets
should not be used in a high powered spring-piston air gun. They do not cushion the
piston sufficiently at the end of travel, and it is like dry-firing and can damage the power plant piston. You can use them in
just about every other type power plant. If you do use them in a spring-piston gun, pack in enough
felt pellets to provide some resistance when the piston comes forward. For an air gun with 800 to 1000 FPS power, perhaps five felt cleaning pellets in a row might
be enough to cushion the piston.
