Prosolv Extreme was developed with three core objectives:

  • Dissolve more lead and copper than any other product on the market
  • Protect gun steel, unlike many cleaners that corrode it over time
  • Be safe to use, with a high flash point

Backed by over 155 years of experience in lubricant development, we put that expertise to work to create this patented formula. After extensive testing and refinement, Prosolv Extreme was engineered to catalytically dissolve up to four times more copper and lead than competing products — all while leaving your steel untouched.

It also dissolves carbon buildup on contact, not just displaces it. And because it’s oil-based rather than solvent-based, any residue left behind continues to protect against rust and lubricate moving parts.

Available in 1 oz and 2 oz bottles.
