Is It Okay to Use WD-40 on a Gun?

For many people, WD-40 is a household essential that fixes everything from creaky doors to rusted bolts. If you’re dealing with gun issues, there’s a chance you might be looking at your WD-40 can and wondering if you can clean your gun with it. However, spraying WD-40 on a gun isn’t a foolproof solution. If you’re new to gun ownership, the ideal first step is to take a gun safety class to learn how to handle your firearm safely, including the proper ways to clean it. Here are some things to know about how WD-40 will affect your gun.

The Difference between WD-40 & Gun Oil

At a glance, WD-40 might seem like it has a similar texture and purpose as gun oil. However, on a chemical level, these two items are very different. Therefore, they have vastly different effects on a gun. Gun oil cleans, lubricates, and protects your gun. While WD-40 is often confused with lubricants and cleaners, it isn’t actually a cleaner. WD-40 is made of a mixture of mineral oil, water repellents, and solvents that aren’t directly harmful to a gun. However, WD-40 evaporates quickly, so it doesn’t lubricate moving parts or prevent your gun from accumulating more grime.

The Problem with Regularly Using WD-40

As you can see, WD-40 is useless if you want to lubricate your gun or protect it from more dirt. It does have some very limited uses as a cleaner, but in most cases, cleaning your gun with WD-40 isn’t recommended because of the way the WD-40 solvent works. When applied to a gun, it will briefly dissolve gunk, but the aerosol applicator will blow all the grime inside the gun’s crevices. 

When WD-40 Is Helpful

Did you know the “WD” in WD-40 stands for “water displacement”? This substance quickly removes water and dries up moisture. Therefore, WD-40 can be useful in emergencies when your gun gets wet. For example, if you accidentally drop your gun in a lake while hunting, a quick spray of WD-40 can dry it off quickly before more damage can be done. Likewise, it can displace water if you’re doing a deep cleaning of a gun that contains some extra moisture.

How to Use WD-40 on a Gun Correctly

Ultimately, WD-40 is fine to use on guns as long as you don’t make a habit out of it. When you need to get rid of some moisture or are out of your favorite cleaner, WD-40 can remove grime and dry out your gun. However, it’s important to use an actual gun cleaner to clean away the coating left behind by WD-40 as soon as you can. Furthermore, make sure you’re not trying to use WD-40 as a gun oil. For the best results, apply a manufacturer-recommended lubricant and protectant to your gun on a regular basis.
