Hoppes 9 Bench Rest Copper Remover 5oz

Hoppe’s Bench Rest 9 Copper Remover for Gun Bores

Hoppe’s Bench Rest 9 Copper Remover is a dedicated copper solvent made for shooters who need a clean, consistent bore. This 5 fl. oz. (150 ml) bottle is the Traditional Bench Rest 9 gun bore cleaner, the same formula bench rest competitors have long used when copper fouling starts to show up in the grooves after a string of jacketed bullets.

As a copper-jacketed bullet travels down the bore, a thin film of copper can smear into the rifling. Left alone, that fouling can affect velocity and make carbon harder to remove. Hoppe’s developed Bench Rest 9 so bench rest shooters and serious hunters can take that copper out overnight, instead of working the bore over three or four days. The solvent is described as powerful, safe, and fast, and it contains no abrasives, so it does not rely on scrubbing compounds to do the work.

What it removes and where it works

Although Bench Rest 9 is known first as a copper-buster, it is also useful for removing powder, lead, and plastic fouling. That makes this 5-ounce bottle a practical cleaner for rifles, and it is also at home on shotguns, pistols, and revolvers when those residues build up. Use it as directed on the label, then protect the bare steel with a quality gun oil when the solvent work is finished, so the bore is not left dry.

The bottle you see here is a compact 5-ounce size that sits easily on a cleaning bench or in a range bag. Keep it tightly capped, away from children, and follow the warnings printed on the label, including eye and aspiration cautions. Wear appropriate protection and work in a well-ventilated area.

Frequently asked questions

How is Bench Rest 9 different from regular Hoppe’s No. 9? Standard No. 9 is a classic bore cleaner. Bench Rest 9 is formulated especially to dissolve copper fouling, and it is intended to clean that copper overnight rather than over several days.

Will it scratch the bore? The formula contains no abrasives. It is a solvent, not a polishing compound, so it is meant to dissolve fouling rather than grind it out.

Can I use it on a shotgun or handgun? Yes. Besides copper in rifle bores, it is also used to remove powder, lead, and plastic fouling from shotguns, pistols, and revolvers.

What should I do after using it? Follow the directions on the bottle, then oil or otherwise protect the metal so the clean bore is not left without a preservative film.
