Why Use a Gun Cleaning Solvent

As any gun owner knows, it’s critical to keep your gun clean and properly maintained. From a safety and useability perspective, you need to frequently clean your firearm. And whether you already have a maintenance routine you love or you’re just getting started, incorporating a gun cleaning solvent is non-negotiable. We’re breaking down exactly what a solvent cleaner is, why you should use one, and which is the best gun cleaning solvent on the market. Let’s jump in.

What is a Gun Cleaning Solvent?

A gun cleaning solvent is a liquid specifically designed to break down debris, residue, and carbon deposits. Each time you fire a gun, a little residue is left behind due to the combustion of the bullet’s primer and gunpowder. In some older or cheaper imported ammunition, the remaining residue from the shot can be corrosive. Higher end ammunition is typically not corrosive, but all that fouling residue buildup can affect the accuracy, reliability, and of course the appearance of the firearm. To avoid your firearm’s barrel getting clogged with carbon deposits, you can use a gun cleaning solvent to help loosen the debris before inserting your bore brush.

Basically, because your gun isn't all that different from an engine or other metal machines, you need something that keeps the metal parts moving, clean and lubricated. That’s why you need a gun cleaning solvent and gun cleaning oil. The solvent breaks down all the debris, so your firearm is clean, and the oil provides a layer of lubrication to keep all the parts in working order.

What Does a Gun Cleaning Solvent Remove?

Whether you’re aware of it or not, your firearm can become very dirty very quickly. You’ll learn why using a solvent cleaner is so important, but first—what needs to be removed in the first place? Well firstly, consider the mud, blood, dirt and debris that can accumulate on the outside of your firearm if you use it to hunt or simply bring it to the range on a rainy day. A gun cleaning solvent can help remove all of that. Plus, you’ll need it to remove carbon build up from gunpowder fouling, copper fouling in the barrel, and any rust that may cause corrosion.

What’s in a Standard Gun Cleaning Solvent?

The most common gun cleaning solvents are either water based, or petroleum based, but you may see other options like alcohol or xylene based. A petroleum-based solvent typically includes acetone, toluene, or heptane to help dissolve oil build-up in the barrel of the firearm. While this makes for a pH neutral solution (more on that later), it’s extremely toxic when inhaled.

Your other alternative is a water-based solvent cleaner. These are lower in toxicity, however it’s not pH neutral. In fact, many water-based solvent cleaners rank around 10.5--the equivalent of rainwater. Perhaps you see where we’re going with this. If you use something to clean your gun with the same pH as rainwater, your firearm is more susceptible to rust than if you were to use a pH-neutral solvent. To avoid this, you can simply rinse the solvent off your gun once you’re done cleaning.

Why is it Necessary to Use a Solvent Cleaner?

It only takes 250 to 300 rounds (or so) for carbon deposits to begin building up in your handgun’s barrel. Rifles, on the other hand, are even less because the more gunpowder your gun uses, the more powder is being burned. If you continue to shoot without using a solvent cleaner, you’re putting your precious weapon at risk. From improved safety and reliability to precise shooting and performance, a solvent cleaner is your gun’s secret to success. Here’s what we mean:



One of the most commons reasons for misfire results from a dirty gun. Dirt and debris buildup in the barrel can prevent a bullet from discharging safely, which can lead to major injury to you (or those around you). By using a gun cleaning solvent, you not only keep your firearm in great shape—you keep it safe, too.


Every time a bullet is fired from your gun, residual carbon particles stick to the barrel. The longer you let that residue build up, the less reliable your firearm becomes. What’s the point of using a gun as protection if it’s not guaranteed to shoot when fired?


Think about it: When there is excess gunk lining the barrel of your gun, it’s hard for a bullet to perform the same way time and time again as the barrel continues to get fouled with more debris. A clean gun is consistent. Many precision rifle shooters have regular cleaning intervals to maintain accuracy and performance. Meaning, if you want the best precision, you need to use a gun cleaning solvent on a regular basis.


Finally, a solvent cleaner will keep your firearm in perfect working condition. Using the best gun cleaning solvent on a regular basis will not only ensure your gun is good to go whenever you need it, a solvent will increase your gun’s lifespan, too. There’s no downside to using a gun cleaner—especially if it’s a non-toxic formula that protects you and your gun.

When and Where Should You NOT Use a Solvent?

While gun solvents are the best way to clean up powder or copper fouling, remember that solvents work because they break down hydrocarbons and other chemicals. Cleaning solvents are great for the barrel, chamber, striker, and other metallic parts that touch ammunition, but they can dull or damage lacquer finishes and wraps because solvents are designed to remove paint. Not to mention, you shouldn’t use solvents on adhesives, fiber-optic sights, and electronic accessories (like that battery in your red dot sight).

How Do You Choose a Gun Solvent?

There are a couple things to consider when trying to pick the right solvent cleaner.

The first thing to consider is the type of solvent you want to use. Do you want a foam or liquid solvent? Each has their own set of pros and cons, but here’s a quick overview:

Foam: Foam solvents are great when you are cleaning a large, broad area, like filling up an entire barrel. This is effective for extremely dirty applications, but often a bit wasteful and messy to deal with.

Liquid: if you choose to use a liquid gun cleaning solvent, you’ve got a couple of options: spray, dropper, or an open bottle. If you choose the bottle, be prepared for a potential mess. A dropper is precise but won’t cover a lot of surface area. Our favorite is a spray because of their wide reach. This type of gun solvent can get into harder-to-reach crevices, whereas foam solvents can’t. They are super easy to use and easily remove buildup.

And finally, the second thing you should consider when choosing a gun cleaner is the price. A great solvent cleaner doesn’t need to break the bank. In fact, our Carbon Killer gun cleaning spray does exactly what it’s named after, all for less than $25. No matter your budget, there is something available for you.
