Non-Toxic Gun Cleaning Solvent FAQs

What Solvent Can I Use to Clean My Gun?

There are different kinds of solvents that can be used to clean guns. They include the following:

Liquid Solvents

Liquid cleaning solvents are perfect if you wish to remove dust, dirt, debris, sand, lead, copper, carbon, or powder fouling from your firearm.

But be careful when dispensing these solvents. It’s best to use them in small quantities, or else they can leave an unpleasant, sticky film that can be rather messy.

Aerosol Spray Solvents

Aerosol spray solvents can effectively eliminate debris and residue. They usually have a thin viscosity, so they can get into hard-to-reach areas of your firearm.

The spray mechanism makes application easy to control, and the force of the air stream will quickly remove any lingering dirt or grime on the surface of the firearm.

Foaming Solvents

If you wish to remove built-up grime and residue from your gun, foaming solvents do the job well. Also, they’re fairly easy to use and apply, and they aren’t as messy as liquid solvents and don’t leave too much sticky residue.

One simple spray of the foam will expand in the bore and ensure maximum coverage. The foam then breaks down and becomes a breeze to wipe away. Practical, right?


A cleaner, lubricant, and protectant (CLP) not only cleans and degreases your gun but also lubricates and protects it from rust and corrosion. It helps to remove built-up residue and debris, and conditions the gun’s surface and interiors.

Again, it’s best to use a light hand when dispensing CLPs. Applying much of it can negatively impact the performance of your gun.

Can I Use WD-40 to Clean My Gun?

The simple answer: no. Do not use WD-40 to clean your gun.

WD-40 is a popular cleaning solvent used mainly in automobiles and home improvement projects. Considering a lot of solvents for gun cleaning are multi-purpose anyway, it’s easy to assume that you can use your spray can of WD-40 to clean your gun and it will work just as well.

But the truth is that WD-40 is not a CLP, although it is touted as such. It is primarily a solvent that can be used for other cleaning purposes, but not for guns. Using WD-40 will only displace the grime and dirt to parts of the gun that are harder to reach.

This will further increase the difficulty of cleaning your gun. It can also slow down your gun’s mechanism and jam it up when you use it in cold weather. WD-40 also evaporates rather quickly, and does not contribute to a gun’s cleaning or maintenance processes.

However, if you are planning to disassemble your gun for its regular deep cleaning, you can use WD-40 if you don’t have any other gun cleaner at home. It effectively repels water and prevents rust and corrosion. Just make sure to clean your gun thoroughly after using WD-40 to prevent displacement of grime and water.

Make sure to apply a lubricant or oil before putting your firearm back together to avoid attracting rust and dirt.

Can I Use Q20 to Clean My Gun?

Q20 is another well-known, multi-purpose lubricant that protects against rust and corrosion. It is a popular choice for light-duty use in homes and garages worldwide.

Q20 is rather cheap and easy to use, and yes, you can use it to remove dirt and grime from your gun. Just be careful while using it on the polymer and rubber components of your firearm, as it is a strong solvent and can damage sensitive materials.

Why Are Some Gun Cleaning Solvents Toxic?

Some gun cleaning solvents contain harsh chemicals that are used for cleaning and degreasing guns but can be toxic if inhaled, ingested, or exposed to the skin of humans or pets.

One of the most commonly used toxic ingredients in gun cleaners is trichloroethylene or TCE, an industrial solvent used for degreasing metal parts. It can negatively affect the liver, kidneys, central nervous system, and reproductive system, and also have an impact on fetal development during pregnancy.

Butoxyethanol is also used in gun cleaners and can affect the eyes, skin, central nervous system, and reproductive system.

Nowadays, however, you can easily buy non-toxic and eco-friendly formulations that do not harm humans, pets, and the environment. The gun cleaning solvents that we have included on this list are all non-toxic.

Final Thoughts

Whether you use your gun regularly or once in a while, cleaning it regularly with a high-quality, effective solvent will help you keep it in great condition and even improve its performance.

Some of the gun cleaning solvents we mentioned on this list even claim to make your gun better than its pre-fired condition, so do try them out and tell us what’s the best gun cleaning solvent among them.

While we are on the topic, let us tell you that gun cleaning doesn’t have to be complicated. You don’t need a heavy-duty solvent tank for gun cleaning. A simple cloth rag, cotton swab, gun brush, pipe cleaners, a bore snake, and a little cleaning solvent are all you need for at-home cleaning.

We hope our guide on the best non toxic gun cleaning solvents helped you discover a product that’s suitable for your specific needs. If you try any of them, do tell us about your experience with them. Or if you use another solvent to clean your gun, we’d love to hear all about that, too!
