What is WD-40?
Before we evaluate its suitability for guns, let’s understand what exactly WD-40 is. It’s more than just a can of magic; it’s a carefully formulated product with a specific purpose. At its heart, WD-40 is a multi-purpose solution, designed to act as a lubricant, penetrant, and water displacer. The name, “WD-40,” itself stands for “Water Displacement, 40th attempt.” This points to its primary initial use, which was to prevent corrosion by displacing water.
Its primary ingredients include a blend of petroleum-based solvents and other additives. These components work together to achieve its versatile properties. The solvents help to dissolve dirt and grime, while the lubricating agents reduce friction. The water displacement aspect is due to the product’s ability to create a barrier between metal surfaces and moisture.
The advantages of WD-40 are readily apparent. It can be effective at removing moisture and preventing rust in the short term. Its penetrative abilities make it useful for loosening stuck parts. The accessibility of the product, readily found in hardware stores and online retailers, is another significant advantage. However, a closer look reveals potential drawbacks that must be considered, especially when dealing with precision instruments like firearms.
Why You Might *Think* WD-40 is Good for Guns
The perception that WD-40 is suitable for gun care arises from several common factors. Firstly, the water displacement properties. A gun’s exposure to moisture is a primary cause of rust and corrosion. WD-40, with its ability to create a protective barrier, appears to offer a readily available solution.
Another contributing factor is the convenience factor. Many gun owners might have WD-40 already on hand, eliminating the need to purchase specialized products. When a gun seems to be sticking or misfiring, the readily available option of WD-40 appears to be a quick fix, offering a moment of relief.
Furthermore, anecdotal evidence and word-of-mouth can fuel this perception. The internet and social media are filled with comments and opinions from people who claim to have successfully used WD-40 on their guns. These positive experiences, while potentially accurate in the short term, don’t always consider the long-term consequences.
In essence, it’s a combination of factors: its readily available status, the apparent effectiveness at displacing water, and the positive experiences that can mislead individuals into thinking it is ideal for their firearms. However, the reality is often more complicated than the surface might suggest.
The Problems with Using WD-40 on Guns
While WD-40 can appear useful at first glance, it possesses several inherent qualities that are not ideal for gun care, and these problems can surface over time.
Lubrication Issues
The primary function of a gun lubricant is to reduce friction between moving parts, which helps to ensure reliable performance and minimize wear. WD-40, though it contains lubricants, is not specifically formulated for the unique demands of firearms. One of the critical flaws is its tendency to evaporate relatively quickly. This leaves the gun’s internal components dry, which can lead to accelerated wear, malfunctions, and potential damage. Frequent reapplication is needed to keep the gun functioning.
Furthermore, the lubricating properties of WD-40, even when it’s present, are not typically designed to withstand the high pressures and temperatures that are common during firing, especially with rapid firing. Its film strength might not be strong enough to effectively protect the metal surfaces under such strenuous conditions. This can lead to metal-to-metal contact, resulting in increased wear and tear.
The formation of gum is another major issue. Over time, WD-40 can oxidize and polymerize, resulting in a sticky, gummy residue. This residue can accumulate in the gun’s action, causing the firearm to malfunction and hindering its smooth operation. The stickiness is compounded by the product’s tendency to attract dirt, dust, and powder residue, further exacerbating the problem. This build-up makes cleaning the gun harder than usual, and this build-up will damage the firearm.
Cleaning Issues
WD-40 is not the optimal solution for cleaning a firearm. While it can help remove some light dirt and grime, it’s not a robust cleaner. Specialized gun cleaning solvents are designed to dissolve powder residue, carbon buildup, and other contaminants effectively. WD-40 lacks the necessary solvency power.
It might not be strong enough to dissolve copper fouling, a significant concern in some rifles. Additionally, certain finishes and materials used in firearms are susceptible to damage from WD-40. Some polymers and wooden gun stocks might be adversely affected by prolonged exposure to the chemicals in WD-40. This exposure can cause discoloration or softening of these parts.
Short-Term vs. Long-Term Corrosion Protection
WD-40 can provide short-term protection against corrosion. It works by displacing water and creating a barrier that shields the metal surfaces from moisture. However, this protection is often temporary. As the lubricant evaporates or is displaced, the protective barrier breaks down, and the firearm becomes vulnerable to rust.
For long-term storage, specialized rust preventatives are far more effective. These products are designed to provide lasting protection, often by forming a stable, non-drying film that resists moisture and oxygen. While WD-40 might offer some immediate benefits, it is not the best choice if the intention is to store your gun for an extended period.
Alternatives to WD-40 for Gun Care
The market is filled with superior alternatives to WD-40. These products are specifically designed to clean, lubricate, and protect firearms.
Cleaning Solvents
These specialized products are the cornerstone of proper gun cleaning. They effectively dissolve carbon, powder residue, and other contaminants. They’re designed not to harm your gun’s finish. Choose solvents specific to the type of fouling you are dealing with.
Lubricants
Proper gun lubricants are formulated to provide long-lasting protection against friction and wear. Many types exist, from lightweight oils for general use to heavy-duty greases for high-stress areas. These lubricants are often designed to adhere to metal surfaces, providing a consistent barrier even under intense firing conditions. These products will make your firearm operate smoother and last longer.
Rust Preventatives
For long-term storage, rust preventatives are essential. These products form a protective layer that shields the metal surfaces from moisture and oxygen, preventing corrosion. These products are critical for maintaining the integrity of your firearm.
CLP Products
Clean, Lubricate, and Protect (CLP) products are popular for their convenience. They combine cleaning, lubricating, and protective properties in a single product. They provide an all-in-one solution for essential gun care.
Best Practices for Gun Maintenance
Proper gun maintenance is the best way to ensure reliable performance and extend the lifespan of your firearm.
Routine Cleaning Schedule
A regular cleaning schedule should be a cornerstone of your gun care routine. After each shooting session, it’s essential to clean the firearm to remove powder residue, carbon buildup, and other contaminants. Even if you haven’t fired your gun, regular cleaning can protect against corrosion.
Disassembly and Proper Cleaning Techniques
The disassembly of your gun is vital before you can begin cleaning. A complete disassembly allows you to access all the critical components that require cleaning and lubrication. Refer to your firearm’s manual for proper disassembly instructions.
Lubrication Points
Ensure you utilize the correct cleaning tools, such as brushes, jags, patches, and rods of the appropriate size. Use high-quality cleaning solvents and lubricants specifically designed for firearms.
After cleaning and lubricating, reassemble the firearm, ensuring all parts are correctly installed. Function-test the firearm to ensure it’s operating correctly. Inspect the gun carefully for signs of wear and tear.
Proper Storage and Humidity Control
Regularly inspect the firearm for any signs of wear and tear, such as rust or damage to the finish. Replace any worn or damaged parts as needed.
When WD-40 Might Be Used on Guns (With Cautions)
Although WD-40 is generally not recommended for routine gun care, there are limited situations where it might be useful with significant caveats.
In emergency situations, such as when the firearm is exposed to water or a more suitable protectant is unavailable, WD-40 can be used to displace moisture. However, it must be followed by a thorough cleaning and application of a dedicated gun lubricant as soon as possible.
It can, in very limited instances, be useful for surface cleaning. If the outside of your firearm has some grime, it can wipe the external parts down. But be sure to follow that with a thorough cleaning and re-lubrication.
The most important takeaway is this: WD-40 should never be considered a substitute for dedicated gun care products. Always follow up with proper cleaning and lubrication using products designed for firearms.
