There are a few good gun care & cleaning products you can buy.
Remington has a new bore cleaning system called SQ-UEEGE. It removes gunk & lead with one pass. The BoreSnske Viper is great too.
Many gunners use Hoppes #9, 7.62 solvent or Butch's. A well made CLP(clean protect lube) can be used as a regular gun care product. Brands include LPX, Ballistol, Gunzilla, and Weaponshield. NOTE: do not use a lot of oil or CLP. Excess oil or lube can cause problems. A small bottle can last a few years.
Brownells is a highly respected source for gunsmithing & cleaning items. See www.brownells.com
