Understanding Rust and Its Causes

What exactly causes your guns to become rusty? Here are three culprits when it comes to rusty guns:

Corrosive Ammunition

There are some types of ammunition that can leave corrosive deposits in the bore, chamber, or bolt face of your weapon. The primer for the ammunition is where the corrosion comes from. When you fire corrosive ammunition, deposits of potassium chlorate are left in the areas of combustion. They turn into salt and then cause oxidation.

High Humidity

Besides causing corrosion, high humidity can cause wooden gunstocks to warp or crack. Be sure to store your guns away from humidity.

Contact With Water

Water is a common cause of rust. Avoid exposure to rain or mist, and be sure to wipe away any moisture from your gun.

11 Best Ways to Keep Your Guns From Getting Rusty

If you are a gun owner looking to protect your precious firearms from rust, look no further! Here are 11 great tips that will help you prevent gun rust.

Know the Difference Between Gun Oil and Solvent

Use Grease To Protect Your Gun From the Elements

Grease your gun to protect it from the elements! Grease is thick and tends to stay in place. It doesn’t get washed off by rain. The grease helps to create a barrier against corrosion.

Avoid Shooting Corrosive Ammo

Some types of ammunition have primer that is corrosive. Even though it might save you money to buy the cheapest ammo, it’s a good idea to invest in ammunition that doesn’t have corrosive properties. This could be the best thing for your gun in the long run! Corrosive ammo can cause a lot of damage.

Keep Your Gun Out of Salt Water

If your gun accidentally gets exposed to salt water, be sure to clean it thoroughly, wiping it down with gun oil. Salt water is a big cause of corrosion.
