Rust is formed when metal is exposed to moisture and oxygen. It causes discoloration and can even cause damage to your firearm.
TIPS FOR RUST PREVENTION
Use rust prevention products.
A lot of cleaning solutions available on the market are multi-purpose since they can also lubricate or protect. Choose cleaning solutions that contain chemicals for rust prevention.
Store your gun properly.
Protect your gun from the elements by keeping it in a moisture-free container, or even better, keep it in a gun safe.
Never leave your gun in a wet condition.
Most guns get damaged when submerged in water. If you’re shooting in the rain, here are some tips to protect your gun from water:
a. Oil your gun
b. Tape your bore
c. Rub lip balm over your scope mount screws
Rub gun oil on your gun when rusting has already started.
At the first sign of rust, apply gun oil to your gun, which will eliminate oxidation and provide another layer of protection the next time you’re out.
