HOP M-PRO Cleaner 4oz Spray - Pack of 12

The Hoppe's M-PRO Cleaner 4oz spray is purpose-built for shooters who want fast, effective bore and action cleaning without the mess or hassle of traditional solvents. This 12-pack of convenient spray bottles makes it easy to keep M-PRO on hand at the range, in the field, or at your cleaning bench—so you spend more time behind the trigger and less time scrubbing carbon buildup. Whether you're maintaining a single rifle or a rotation of firearms, having a pack of ready-to-use bottles means you're never caught short when fouling starts to accumulate.

M-PRO Cleaner tackles the real residue that fouls modern firearms: carbon deposits, lead, and copper fouling that degrades accuracy and reliability over time. The ammonia-free formulation is gentler on finishes and your hands than harsh traditional cleaners, while remaining tough on buildup. Because it's non-flammable, it's also safer to use indoors, in vehicles, or anywhere ventilation is limited—making it practical for hunters, competitive shooters, and gunsmiths alike.

The 4oz spray bottle format is the sweet spot for field or range use: portable enough to toss in a range bag, large enough to get real work done without constant refilling. Grab a pack and keep your firearms running clean and reliable without compromise.

Frequently Asked Questions

What does M-PRO Cleaner remove from firearms?

M-PRO Cleaner is formulated to dissolve carbon deposits, lead residue, and copper fouling—the three main contaminants that accumulate in gun bores and actions during shooting. This makes it effective for routine cleaning after range sessions or field use.

Is Hoppe's M-PRO safe to use indoors?

Yes. The cleaner is non-flammable and ammonia-free, making it safer to use indoors, in vehicles, or other enclosed spaces compared to harsh traditional solvents. That said, basic ventilation is always a good practice when cleaning any firearm.

Why buy a 12-pack of 4oz bottles instead of one large container?

A dozen 4oz bottles give you portability and convenience. Keep spray bottles in your range bag, truck, cleaning bench, and safe without taking up much space. It's also easier to grab one bottle for a quick cleaning than managing a larger jug, and the pack ensures you're never without cleaner when you need it.

Will M-PRO Cleaner damage firearm finishes?

The ammonia-free formulation is designed to be gentler on firearm finishes than ammonia-based cleaners, making it suitable for use on blued, chrome-moly, and other standard finishes. As with any solvent, avoid prolonged contact with sensitive areas and always follow manufacturer guidance for your specific firearm.
