Hoppe’s No. 9 Bench Rest Copper Remover – Overnight Copper Fouling Removal for Rifles, Shotguns & Handguns

Copper fouling is the enemy of accuracy. As jacketed bullets travel down the bore, copper from the bullet jacket deposits in the rifling — building up over hundreds of rounds and progressively degrading accuracy as the bore’s geometry changes. Standard bore solvents remove powder fouling effectively but struggle with copper, often requiring hours of soaking and repeated scrubbing to make a dent. Hoppe’s No. 9 Bench Rest Copper Remover is formulated specifically for the job — a powerful chemical solvent that dissolves copper fouling overnight so you can wipe it out the next morning without aggressive scrubbing.

Overnight Copper Removal

The Bench Rest formula’s key advantage over standard solvents is its ability to dissolve copper fouling with an overnight soak rather than requiring 3 or 4 days of repeated applications. Saturate a patch, run it through the bore, and let the solvent work overnight. By morning, the copper fouling has been chemically dissolved and can be wiped out with a clean patch — leaving a bore that’s clean down to the metal without aggressive bronze brush scrubbing that can accelerate bore wear.

No Abrasives – Safe for All Bores

Hoppe’s Bench Rest Copper Remover contains no abrasives — it removes copper fouling through chemical action, not mechanical scrubbing. That makes it safe for all bore types including stainless steel, chrome-lined, and lapped match barrels where abrasive cleaners can damage the carefully finished bore surface. The powerful, safe formula is equally effective on powder fouling, lead deposits, and plastic wad fouling from shotgun bores.

Formulated for Bench Rest Shooters

Bench rest shooters demand the cleanest possible bore for maximum accuracy — and Hoppe’s Bench Rest Copper Remover was developed specifically to meet that standard. It’s equally valuable for hunters who want to maintain peak accuracy from their hunting rifles throughout the season, and for any shooter who wants to know their bore is truly clean rather than just clean enough.
