This guide details the process of removing stubborn Cosmoline from surplus firearms, specifically Chinese Type 56 SKS carbines. It covers field stripping, using heat to 'sweat' Cosmoline from wood, sonic cleaning small parts, and employing non-chlorinated brake cleaner for metal components. Safety precautions, such as ensuring the firing pin channel is clear to prevent slam fires, are emphasized.

Quick Summary

To remove Cosmoline from wooden rifle stocks, place them in a trash bag in direct sunlight (115-125°F) to 'sweat' the grease out. For metal parts, use non-chlorinated brake cleaner with gloves and ventilation. Ensure the SKS firing pin channel is completely clear to prevent slam fires.

Frequently Asked Questions

What is the best way to remove Cosmoline from wooden rifle stocks?

Place wooden rifle stocks in a trash bag and leave them in direct sunlight. The heat, typically between 115-125°F, will 'sweat' the Cosmoline out of the wood fibers, making it easier to wipe away.

What type of cleaner should I use for metal parts covered in Cosmoline?

Use a non-chlorinated brake cleaner for metal components. It's crucial to avoid chlorinated versions, as they can create toxic phosgene gas if the metal is heated later. Always ensure good ventilation and wear gloves.

Why is it important to clean the firing pin channel on an SKS rifle thoroughly?

The SKS has a free-floating firing pin. If Cosmoline residue causes it to stick forward, it can lead to dangerous slam fires when the bolt closes, making a completely clear channel essential for safety.

Can I use an ultrasonic cleaner for Cosmoline removal?

Yes, an ultrasonic cleaner is very effective for small metal parts and springs. It helps loosen hardened Cosmoline and grime in tight spaces, significantly reducing the need for manual scrubbing.
