Preserving firearm magazines often involves the use of a petroleum-based preservative known as cosmoline. This thick, waxy substance effectively protects metal components from corrosion during storage and transport. However, before the magazine can be reliably used, the cosmoline must be thoroughly removed.
Maintaining a firearm magazine’s functionality and reliability necessitates this cleaning process. A build-up of preservative can interfere with the smooth feeding of ammunition, potentially leading to malfunctions or jams. Proper cleaning ensures consistent performance and extends the lifespan of the magazine. Historically, cosmoline has been a crucial element in the long-term storage of military surplus firearms and their associated components, ensuring they remained operational even after extended periods of inactivity.
