HOP M-PRO 2oz Copper Cleaner Spray - Pack of 12

Hoppe's M-PRO Copper Cleaner Spray is a specialized solvent designed to remove copper fouling buildup from rifle and pistol barrels. Copper deposits accumulate in the bore during shooting and degrade accuracy over time—this 2oz spray bottle targets that problem directly. Each pack contains 12 bottles, making it economical for shooters who clean regularly or run a range where multiple firearms need maintenance. The spray format delivers the cleaner exactly where you need it, cutting application time compared to liquid in a pour bottle.

Copper fouling is one of the most persistent challenges in gun maintenance. It doesn't rinse away with standard bore cleaners; you need a chemical formulated to dissolve and remove it. M-PRO cuts through oxidation and buildup on barrel steel without the tedious scrubbing that older copper removers demand. For hunters and competitive shooters who fire enough rounds to see accuracy shifts, keeping barrels clean of copper is non-negotiable. The 12-pack format means you can stock your cleaning kit, your range bag, and still have backups on hand.

The spray bottle makes targeted application straightforward—no measuring, no mess. This is the kind of product that lives in a gun bag, gets passed around the range, or stays in a cleaning kit year-round. Hoppe's has built a reputation on effective gun-care chemistry that works, and this copper cleaner is a staple for shooters serious about bore maintenance.

Frequently Asked Questions

What is copper fouling and why do I need to remove it?

Copper fouling is residual copper plating left in the rifle bore after firing. It builds up over time, reduces accuracy, and doesn't respond to standard bore cleaning solvents. A specialized copper cleaner like M-PRO dissolves and removes it, restoring bore condition and maintaining shot consistency.

Can I use this on both rifles and pistols?

Yes. M-PRO Copper Cleaner is formulated for removing copper fouling from both rifle and pistol barrels.

Why buy a 12-pack instead of a single bottle?

The 12-pack is more economical if you shoot frequently or maintain multiple firearms. You can keep bottles in your range bag, cleaning kit, truck, and home without running out. It's also practical for instructors, range operators, or hunting camps where several people clean guns regularly.

How do I apply the spray?

Use the spray bottle to apply the cleaner directly into the bore or onto a patch. The spray format eliminates measuring and makes application quick and mess-free.
