Rust layers can occasionally form on firearms due to the hunting season, summer months, or humid weather conditions. According to experts, if the rusting is still at a superficial level, it is often possible to easily clean the slight oxidation on the metal surface using a small amount of oil and a clean cloth.
For more significant rusting, cleaning materials that do not damage the surface, such as steel wool, are recommended. In particular, 4/0 grade fine steel wool, when used with a suitable oil or cleaner, allows for the removal of rust from the surface without damaging the bluing.
It is noted that pitting revealed during cleaning may be permanent and can only be remedied by a professional re-finishing process. Once the cleaning process is complete, it is recommended that the firearm be wiped down completely with a general maintenance oil.
According to experts, the most important way to prevent rusting is to avoid placing firearms in cases immediately after returning from humid environments. It is stated that sudden changes in temperature and humidity cause condensation on the metal surface, increasing the risk of rusting.
