## Understanding Brass Shells and Their Care
Brass shells, commonly used in ammunition, are prized for their durability, malleability, and corrosion resistance. However, brass is still susceptible to tarnishing and corrosion over time, especially when exposed to moisture, humidity, and certain chemicals. Proper care is essential to maintain the integrity and longevity of these shells, whether you’re a collector, reloader, or simply want to preserve your ammunition.
### The Composition of Brass
Brass is an alloy primarily composed of copper and zinc. The specific ratio of these metals can vary, resulting in different types of brass with varying properties. Cartridge brass, typically used in ammunition, is often a 70/30 copper-zinc alloy, offering a good balance of strength and ductility. Understanding the composition of brass is crucial for selecting appropriate cleaning and preservation methods.
### Common Issues Affecting Brass Shells
* **Tarnish:** A dull, discolored surface layer caused by oxidation and reaction with atmospheric elements.
* **Corrosion:** A more severe form of degradation that can weaken the brass and compromise its structural integrity.
* **Verdigris:** A greenish coating formed by the reaction of copper with moisture and acids, often seen on older brass items.
* **Fingerprints and Oils:** Oils from handling can accelerate corrosion and attract dirt, leading to further degradation.
### Why Proper Care Matters
Proper care of brass shells is essential for several reasons:
* **Preservation:** Maintaining the aesthetic appeal and historical value of collectible shells.
* **Reloading:** Ensuring the structural integrity and dimensional accuracy of shells for safe and reliable reloading.
* **Functionality:** Preventing corrosion and damage that can affect the performance and reliability of ammunition.
## WD-40: A Closer Look at Its Properties and Uses
WD-40 is a widely recognized and versatile product known for its water displacement, lubrication, and rust prevention properties. However, its suitability for use on brass shells requires careful consideration. Understanding its chemical composition and potential effects is crucial before applying it to your valuable casings.
### What is WD-40?
WD-40 is a petroleum-based solvent and lubricant. Its formula is a closely guarded secret, but it’s known to contain a mixture of aliphatic hydrocarbons, mineral oil, and other ingredients designed to penetrate, displace moisture, and provide a protective barrier against corrosion.
### Common Uses of WD-40
WD-40 is commonly used for:
* Loosening rusted bolts and screws
* Displacing moisture from electrical contacts
* Lubricating moving parts
* Preventing rust and corrosion on metal surfaces
* Cleaning and degreasing tools and equipment
### The Potential Benefits of Using WD-40 on Brass
WD-40 can offer some potential benefits when used on brass:
* **Water Displacement:** It can help remove moisture from the surface of the brass, preventing corrosion.
* **Cleaning:** It can dissolve some dirt and grime, helping to clean the surface of the brass.
* **Protection:** It can leave a thin, protective film that helps to prevent oxidation and corrosion.
### The Potential Drawbacks of Using WD-40 on Brass Shells
Despite its potential benefits, WD-40 also has some drawbacks when used on brass shells:
* **Residue:** It can leave a sticky residue that attracts dust and dirt, potentially accelerating corrosion over time.
* **Not a True Cleaner:** It’s not a dedicated brass cleaner and may not effectively remove heavy tarnish or corrosion.
* **Potential for Damage:** Some ingredients in WD-40 can react with brass over time, potentially causing discoloration or damage. While this is debated, it’s a risk to consider.
* **Reloading Concerns:** If used on shells intended for reloading, WD-40 residue can affect primer seating and powder ignition, leading to misfires or inconsistent performance. It’s imperative to completely remove all traces of WD-40 before reloading.
## Can You Use WD-40 on Old Brass Shells? The Verdict.
So, *can you use WD-40 on old brass shells*? The answer is nuanced. While WD-40 *can* be used in certain situations, it’s generally *not recommended* as the primary or long-term solution for cleaning and preserving brass shells. The potential drawbacks, such as residue buildup and potential for damage, outweigh the limited benefits it offers. It’s better suited as a temporary moisture displacer than a dedicated brass cleaner or preservative.
### When WD-40 Might Be Acceptable (With Caveats)
* **Emergency Moisture Displacement:** If your brass shells have been exposed to moisture and you need a quick solution to prevent rust, WD-40 can be used sparingly. However, it’s crucial to thoroughly clean the shells with a proper brass cleaner afterward.
* **Light Cleaning (Followed by Proper Cleaning):** For removing light dirt and grime, WD-40 can be used as a pre-cleaner, but always follow up with a dedicated brass cleaner to remove any residue.
### When WD-40 Should Be Avoided
* **Heavily Tarnished or Corroded Brass:** WD-40 is not effective at removing heavy tarnish or corrosion. Use dedicated brass cleaners for these situations.
* **Brass Shells Intended for Reloading:** The residue left by WD-40 can interfere with the reloading process. Avoid using it on shells you plan to reload, or ensure it’s completely removed before reloading.
* **Long-Term Storage:** WD-40 is not a suitable long-term preservative for brass shells. Use dedicated brass preservatives for long-term storage.
## Expert-Recommended Alternatives for Cleaning and Preserving Brass Shells
Instead of relying on WD-40, consider these expert-recommended alternatives for cleaning and preserving your brass shells:
### Brass Cleaners
Dedicated brass cleaners are specifically formulated to remove tarnish and corrosion without damaging the brass. They come in various forms, including liquids, pastes, and cloths. Some popular options include:
* **Brasso:** A classic brass cleaner that effectively removes tarnish and leaves a polished finish.
* **Flitz:** A versatile metal polish that can be used on brass, copper, and other metals.
* **CLR (Calcium, Lime, Rust Remover):** While primarily designed for removing hard water stains, CLR can also be used to clean brass, but it’s important to dilute it properly and rinse thoroughly.
### Ultrasonic Cleaners
Ultrasonic cleaners use high-frequency sound waves to create cavitation bubbles in a cleaning solution, effectively removing dirt and grime from brass shells. They are particularly useful for cleaning the inside of casings.
### Tumbling with Media
Tumbling brass shells with media, such as walnut shells or corncob, is a popular method for cleaning large quantities of casings. The media abrasively removes dirt and tarnish, leaving the shells clean and polished.
### Brass Preservatives
Brass preservatives are specifically designed to protect brass from tarnish and corrosion during long-term storage. They typically contain corrosion inhibitors that create a protective barrier against moisture and atmospheric elements. Some popular options include:
* **Renaissance Wax:** A microcrystalline wax that provides a long-lasting protective coating for brass and other metals.
* **Boeshield T-9:** A waterproof lubricant and corrosion protectant that can be used on brass.
* **Inhibitor VCI bags:** Vapor corrosion inhibitor bags that protect brass from corrosion during storage.
## Step-by-Step Guide to Cleaning Brass Shells Using Recommended Methods
