The question of whether or not to use WD-40 on brass shells is a common one among firearm enthusiasts and collectors. The short answer is: it's generally not recommended, and here's why. While WD-40 might seem like a handy lubricant, its long-term effects on brass can be detrimental. This post delves into the specifics, exploring the potential benefits, drawbacks, and safer alternatives for maintaining your brass shell casings.
Understanding WD-40's Composition and Limitations
WD-40, while effective for displacing water and lubricating certain mechanisms, isn't designed for long-term use on delicate metals like brass. Its formulation includes solvents and petroleum distillates that can:
- Dissolve protective coatings: If your brass shells have any protective coatings or finishes, WD-40 can strip them away, leading to corrosion and tarnishing.
- Attract dirt and grime: The oily residue left behind by WD-40 can act as a magnet for dust and other contaminants, potentially accelerating the deterioration process.
- Interfere with reloading: Residue from WD-40 might interfere with the proper functioning of reloading equipment, potentially leading to malfunctions or damage.
Potential Short-Term Benefits vs. Long-Term Damage
While applying WD-40 might temporarily seem to reduce sticking or remove surface moisture, these benefits are short-lived. The long-term consequences significantly outweigh any immediate advantages:
- Corrosion: The solvents in WD-40 can accelerate the corrosion process over time, weakening the brass and potentially rendering the shells unusable.
- Tarnishing: The oily residue can leave a dull film on the brass, affecting its appearance.
- Contamination: The residual oil can contaminate the gunpowder and primers, leading to unreliable firing.
Safer Alternatives for Cleaning and Preserving Brass Shells
For cleaning and maintaining your brass shells, consider these safer and more effective alternatives:
1. Brass Cleaning Solutions:
Specifically formulated brass cleaners are available from various retailers. These are designed to effectively clean brass without causing damage or leaving harmful residues. They are usually gentler on the metal and will preserve the integrity of the casings better than WD-40.
2. Lubricants Designed for Firearms:
Use high-quality firearm lubricants designed for this purpose. These lubricants are formulated to withstand the high temperatures and pressures of firearm operation while protecting the metal from wear and tear. These are far superior to WD-40 for any lubrication needs.
3. Simple Soap and Water:
For general cleaning, a mild soap and water solution can effectively remove dirt and grime. Be sure to thoroughly rinse and dry the shells afterward.
Conclusion: Prioritize Proper Care of Your Brass Shells
While WD-40 might seem like a quick fix, it ultimately compromises the long-term health and value of your brass shells. Opting for specialized brass cleaners and firearm lubricants ensures the longevity and proper functioning of your valuable reloading components. Proper cleaning and maintenance will keep your brass looking good and performing at its best for many reloads. Remember, investing in the right products from the start is far more economical and less problematic than attempting repairs or replacements later.
