Duration: 1:45

This guide details the proper procedure for cleaning firearms exposed to corrosive ammunition, as demonstrated by a Brownells Technician. It emphasizes immediate water flushing to neutralize salts from primers, which can cause rust and pitting. The process involves disassembling affected parts, soaking them in water, brushing, and thorough drying, with specific attention to the barrel. Water-based solvents are presented as an alternative for those hesitant to use plain water.

Quick Summary

The most effective way to clean corrosive ammunition residue is to immediately flush firearm parts that contacted propellant gases with water. This dissolves the salts. After flushing, brush the parts, dry them thoroughly (using compressed air is recommended), and then proceed with standard bore cleaning.

Frequently Asked Questions

What is the best way to clean corrosive ammunition residue?

The most effective method is to immediately flush firearm parts that contacted propellant gases with water after firing. This dissolves the corrosive salts. Follow up by brushing, thorough drying, and then standard cleaning procedures for the bore.

Why is corrosive ammunition dangerous to firearms?

Corrosive ammunition primers contain salts that, when exposed to humidity, form acids. These acids can cause rust and pitting on metal firearm components, leading to long-term damage if not properly cleaned soon after firing.

What firearms are commonly associated with corrosive ammunition?

Surplus military ammunition, often used in firearms like the SKS, AK-pattern rifles, and Mosin Nagant rifles, is frequently corrosive. Proper cleaning is essential for maintaining these platforms.

Can I use regular cleaning solvents for corrosive ammo?

While specialized water-based solvents like Brownells Ed's Red or Shooter's Choice Aqua Clean can help neutralize corrosive residues, the primary and most effective immediate step is flushing with plain water to dissolve the salts.
