## Understanding Brass Shells and Their Care
Brass shells, often used in ammunition, are susceptible to tarnishing, corrosion, and other forms of degradation over time. Understanding the composition of brass and the factors that contribute to its deterioration is crucial for proper care and maintenance. Brass is primarily an alloy of copper and zinc, and the specific ratio of these metals can affect its properties, including its resistance to corrosion. Improper storage, exposure to moisture, and handling with bare hands can all accelerate the tarnishing process.
### The Composition of Brass
Brass, as an alloy of copper and zinc, exhibits varying properties depending on the percentage of each metal. Cartridge brass, commonly used for ammunition shells, typically contains around 70% copper and 30% zinc. This composition offers a good balance of strength, ductility, and corrosion resistance. However, even with this composition, brass is still vulnerable to environmental factors that can cause it to tarnish and corrode.
### Common Problems with Brass Shells
* **Tarnishing:** The most common issue, caused by oxidation of the copper in the brass, resulting in a dull, discolored surface.
* **Corrosion:** A more severe form of degradation, often caused by exposure to moisture and acidic substances. This can lead to pitting and weakening of the shell.
* **Green Verdigris:** A greenish coating that forms on brass exposed to moisture and air. This is a form of copper corrosion and can be difficult to remove.
* **Dents and Scratches:** Physical damage that can affect the shell’s appearance and potentially its functionality.
## WD-40: What It Is and What It Does
WD-40 is a widely used product known for its versatility. However, it’s essential to understand its composition and intended use before applying it to sensitive materials like brass shells. WD-40’s primary function is as a water displacement and lubricant, but it also contains solvents and corrosion inhibitors.
### The Composition of WD-40
WD-40’s exact formula is a trade secret, but it is known to contain a mixture of petroleum-based solvents, lubricants, and corrosion inhibitors. These ingredients work together to penetrate rust, displace moisture, and provide a protective layer against corrosion. However, the solvents in WD-40 can also have unintended effects on certain materials, including brass.
### How WD-40 Works
* **Water Displacement:** WD-40 effectively displaces water, preventing rust and corrosion.
* **Lubrication:** Provides a thin layer of lubrication, reducing friction between moving parts.
* **Penetration:** Penetrates rust and corrosion, loosening stuck parts.
* **Cleaning:** Can dissolve some types of dirt and grime.
## Can You Use WD-40 on Old Brass Shells? The Answer
While WD-40 can be tempting to use on old brass shells due to its cleaning and protective properties, it’s generally **not recommended** as a primary cleaning or long-term preservation solution. The solvents in WD-40 can potentially react with the brass, leading to discoloration or, in some cases, accelerated corrosion over time. While it might provide a temporary shine, the long-term effects can be detrimental.
### Potential Risks of Using WD-40 on Brass
* **Discoloration:** The solvents in WD-40 can cause brass to darken or develop an uneven color.
* **Residue Buildup:** WD-40 can leave a sticky residue that attracts dust and dirt, making the shell look even dirtier over time.
* **Corrosion Acceleration:** In certain environments, the ingredients in WD-40 can actually accelerate corrosion rather than prevent it.
* **Interference with Patina:** For antique brass shells, WD-40 can strip away the natural patina, reducing their value and historical significance.
### Expert Opinion on WD-40 and Brass
Leading experts in brass preservation generally advise against using WD-40 for cleaning or protecting brass items, including shells. They recommend using specialized brass cleaners and protectants that are specifically formulated to be safe for brass and provide long-term protection without causing damage.
## Safer Alternatives for Cleaning Brass Shells
Fortunately, several safer and more effective alternatives exist for cleaning and preserving brass shells. These methods are specifically designed to protect the brass while removing tarnish and grime.
### Recommended Cleaning Methods
* **Mild Soap and Water:** For light cleaning, mild soap and water can be effective. Use a soft cloth to gently wipe the shell, then rinse thoroughly and dry completely.
* **Brass Cleaners:** Commercial brass cleaners are specifically formulated to remove tarnish and restore shine without damaging the brass. Follow the manufacturer’s instructions carefully.
* **Baking Soda Paste:** A paste made from baking soda and water can be used to gently scrub away tarnish. Rinse thoroughly and dry completely.
* **Vinegar and Salt Solution:** A solution of vinegar and salt can also be used to remove tarnish. Soak the shell in the solution for a few minutes, then scrub gently and rinse thoroughly.
### Recommended Preservation Methods
* **Renaissance Wax:** A microcrystalline wax polish that provides a protective barrier against moisture and corrosion. It is widely used by museums and collectors for preserving valuable artifacts.
* **Lacquer Coating:** A clear lacquer coating can be applied to brass shells to protect them from tarnishing. However, this is a more permanent solution and may not be suitable for all shells.
* **Proper Storage:** Storing brass shells in a cool, dry place in airtight containers can help prevent tarnishing and corrosion.
