Barnes CR-10 Bore Cleaner 2 oz.

Barnes’ specially formulated 2 oz. CR-10™ Bore Cleaning Solvent effectively removes copper, brass and lead fouling. This aggressive bore cleaner quickly loosens and lifts heavy copper deposits left by jacketed bullets as they pass through the bore. Leaves rifling clean for better accuracy and longer barrel life. CR-10 bore cleaner is non-corrosive and won’t harm barrels.

CR-10 along with most other copper cleaning solvents, contains ammonia to remove the copper. Ammonia attracts moisture, which in turn causes the clean steel to rust very quickly. Barnes has tested barrels submerged in CR-10 for 18 months without any damage to the barrel. An oil patch is recommended after cleaning to prevent the rust process.


  • Contains Ammonia to agressively dissolve copper fouling from your gun's bore
  • Will not damage barrels when used as directed


  • Also available in 8 oz. bottle
  • When shooting pure COPPER BULLETS, it is especially important to start with a very clean bore. A small amount of harder gliding metal fouling will strip material from the softer pure copper and accelerate fouling.
  • The ammonia in CR-10 will react with the copper in your barrel to create the blue discoloration you see on your patches. Barnes  recommends running CR-10 soaked patches through your barrel until they come out virtually clean. For excessive fouling, alternate soaked patches with a CR-10 soaked bronze brush to increase scrubbing intensity. Run a dry patch on a jag through the bore to wipe out most of the CR-10. When finished, remove any excess CR-10 left in the bore with a non-chlorinated brake cleaner soaked patch. Repeat until all CR-10 is removed from the bore. Remember to follow the directions included with the product and don’t leave the CR-10 in the bore for more than fifteen minutes.


  • Harmful if inhaled in excess amounts. Use only with adequate ventilation. Harmful if ingested and to eyes. Gloves are recommended, as it may irritate skin on contact.
