Solvents & cleaners for deep firearm cleaning and carbon removal
Carbon doesn't negotiate. It builds up shot after shot — slowing your action, increasing wear, and setting the stage for malfunctions when it matters most. GNP Defend Solvents & Cleaners cut through it fast, dissolving fouling, grease, and old lubricant residue without harming your metals, polymers, or coatings.
Why proper solvent cleaning matters
Every range session leaves behind unburned powder, carbon deposits, and degraded oil. A dedicated solvent flush removes what patches alone can't, giving you a clean foundation before fresh lubrication goes on.
Breaks down stubborn carbon and fouling fast
Strips old grease and degraded oil residue
Prepares metal surfaces for maximum lubricant adhesion
Safe for modern metals, polymer frames, and factory coatings
Works on pistols, rifles, shotguns, and tactical builds
Complete your maintenance workflow
Step 1
Solvent clean
Flush fouling, carbon, and degraded oil from every surface and moving part.
The best solvent dissolves carbon and fouling without leaving behind residue or damaging your finish. GNP Defend formulas are fast-acting, clean-rinsing, and safe for modern firearm materials including metals, polymer frames, and factory coatings.
Cleaner removes what shouldn't be there. Oil protects what is. Use solvent first to strip fouling and old lubricant residue, then apply a gun oil to reduce friction and guard against corrosion. Skipping either step shortchanges your maintenance.
No — WD-40 is a water displacer, not a firearm solvent or lubricant. It leaves an oily film that attracts debris, doesn't break down carbon effectively, and offers no long-term corrosion protection. Use a purpose-built firearm cleaner instead.
After every range session is ideal for defensive firearms, while occasional shooters can clean every few hundred rounds. Read our full guide for recommendations by firearm type: How often should you clean your firearm? →
