Thread: Cleaning Heavy Copper

I fill my barrel with Wipe Out Bore Foam as soon as I get home, first thing. Then, unload the the vehicle, have a coffee, yarn with the family, then return to finish the barrel cleaning.
Generally the foam does a good job but will also use Wipe Out Patch Out plus Accelerator on occasion.

Wipe Out products have always been hard to source but more so now of course.

If I still have copper (check with bore scope) I'll attack it further with Boretech Cu+ or KG12. Boretech Eliminator is OKish just, for copper, but Cu+ much much better as it's a dedicated Cu solvent.

If the barrel is one that resists all those I will mechanically clean it with an abrasive cleaner like USP Bore Paste or Autosol. Thankfully I don't have more than 1 barrel like that. Generally any barrel that presents me with that much bother usually doesn't live in my safe for long. My service rifles excepted.

Carbon rings I attack with USP Bore Paste or Autosol with localised cleaning.

Long since got rid of my ammonia based cleaners. Whether they damage barrels I won't get into that discussion it's just the likes of Boretech Cu+ and KG12 are superior.
