The barrel of a gun is one of the most important parts. It requires frequent maintenance and inspection. A common phenomenon that affects gun bore is copper fouling. If left unattended, it can reduce the efficiency of your firearm.
Getting a good bore cleaner can solve this problem. Unfortunately, this is not an easy task as there are several varieties. In this buying guide, we’ll go over the best bore cleaners for copper fouling, how you can choose them, and answer your frequently asked questions.
What is Copper Fouling?
Copper fouling is usually a blue-green coloring that appears along the grooves of the barrel. Copper fouling is mostly caused by firing copper bullets. Hot gas from the burning powder leaves a thin layer of copper. This copper can eventually build up in the bore and affect accuracy.

How To Choose a Good Bore Cleaner
There are so many bore cleaners with different features and purposes. It’s easy to get lost when searching for the best bore cleaner for your gun. This guide will give you the important factors to consider to save you time and stress.
1. Type of Gun
The type of gun you have determines the solvent that’s best for you. If you have a small collection of similar guns, you can get an all-in-one cleaner. However, if your gun collection cuts across various types, it might be best to purchase a bore cleaner that suits your specific type of gun.
Your type of gun matters because some solvents aren’t harsh enough to remove copper from every surface. Some guns also accumulate copper faster than others.
The ingredients of the solvent are also a great indicator of whether it will be best for you. If you’re opposed to a toxic cleaner, Hoppe’s 9 wouldn’t be a good choice for you. Also, if you can’t stand the smell of ammonia, you might steer clear of Pro-Shot Copper Solvent IV.
The cost of bore cleaners is another way you can choose one for your rifle. While most people will tell you to steer clear of expensive ones, we suggest you consider them. Usually, the higher the price, the more value it delivers. High-priced cleaners should produce quality results.
However, if there are cheaper cleaners that have the same features as expensive ones, you should go for the cheaper ones. Either way, you shouldn’t sacrifice quality for your budget. You shouldn’t compromise on your budget for a quality cleaner either.
Another factor to consider when choosing a good bore cleaner for copper fouling is what you intend to use it for. If you need one that removes copper fouling, you should check if the product you choose does that.
