As a long-time outdoorsman and firearms enthusiast, I’ve spent years maintaining my equipment in the field and at home. One question I consistently encounter from fellow shooters is: can you use WD-40 on guns? The answer is… complicated. While WD-40 for cleaning guns is a readily available and tempting solution, it’s crucial to understand its limitations and when it’s appropriate – and when it’s not. This guide will delve into using WD 40 to clean a gun, comparing it to dedicated gun oils, and ensuring you maintain your firearm safely and effectively. We'll cover everything from basic cleaning to long-term storage, always prioritizing responsible gun ownership.
WD-40, originally formulated by the Rocket Chemical Company in 1953 for corrosion prevention on missiles (hence the name “Water Displacement, 40th formula”), is a penetrating oil and water displacer. It excels at loosening rusted parts and preventing corrosion. However, it’s not a lubricant in the traditional sense. According to WD-40’s official website, it’s a solvent, cleaner, and moisture barrier. This distinction is vital when considering wd40 for gun cleaning.
WD-40’s primary components include petroleum distillates, mineral oil, and various additives. While it effectively removes fouling, carbon buildup, and old lubricant, it doesn’t offer the long-lasting lubrication needed for the moving parts of a firearm. Prolonged use as a sole lubricant can actually attract dirt and grime, potentially leading to malfunctions. Think of it as a fantastic initial cleaner, but not a long-term protector. The National Shooting Sports Foundation (NSSF) emphasizes the importance of proper lubrication for firearm reliability.
Yes, you can clean a gun with WD-40, but it should be part of a more comprehensive cleaning process. Here’s how I approach it:
Understanding the difference between gun oil and WD-40 is paramount. Here’s a breakdown:
| Feature | Gun Oil | WD-40 |
|---|---|---|
| Primary Function | Lubrication & Corrosion Protection | Cleaning, Water Displacement, & Light Corrosion Prevention |
| Lubricity | Excellent, long-lasting | Minimal, temporary |
| Viscosity | Varies depending on type (light, medium, heavy) | Low |
| Residue Attraction | Minimal with quality oils | Can attract dirt and grime |
| Long-Term Protection | Superior | Limited |
As you can see, gun oil is specifically formulated to reduce friction, protect against wear, and prevent corrosion. WD-40 excels at cleaning and displacing water, but it lacks the lubricating properties necessary for reliable firearm operation. REI Expert Advice (REI) strongly recommends using dedicated gun lubricants for optimal performance.
While not a replacement for gun oil, WD-40 on guns has specific applications where it shines:
For long-term storage (months or years), relying solely on WD-40 is a mistake. While it can displace moisture, it doesn’t provide the long-lasting corrosion protection needed to prevent rust. The USDA Forest Service (USDA FS) provides excellent resources on metal preservation, which apply to firearms as well. Instead, use a dedicated gun storage oil or grease, and consider using desiccants to absorb moisture. A properly stored firearm will be ready for action when you need it.
Generally, yes, you can use WD-40 on my gun’s polymer parts. WD-40 is typically safe for most polymers, but it’s always best to test a small, inconspicuous area first. Avoid prolonged exposure, as some solvents can potentially degrade certain plastics over time. Always wipe off any excess WD-40.
Even when cleaning firearms, we should adhere to the principles of Leave No Trace (Leave No Trace). Properly dispose of used cleaning solvents, cloths, and packaging. Avoid cleaning firearms near waterways or sensitive areas. Responsible gun ownership extends to environmental stewardship.
To reiterate, wd40 to clean gun is a useful tool in a gun owner’s arsenal, but it’s not a complete solution. Think of it as a powerful cleaner and penetrant, but always follow up with a quality gun oil for lubrication and long-term protection. By understanding its limitations and using it appropriately, you can keep your firearms in top condition for years to come. Remember, responsible gun ownership includes proper maintenance, safe handling, and a commitment to ethical shooting practices.
