FrogLube Solvent Spray is a petroleum-free, bio-based cleaner for firearms. It is the cleaning half of a clean-then-lube routine: spray it on to cut carbon fouling and residue, wipe the parts down, then follow with a lubricant or CLP. The formula is non-toxic and biodegradable. Features: Petroleum-free, bio-based cleaning solvent Cuts carbon fouling and shooting residue Non-toxic and biodegradable No HAZMAT shipping; CA Prop 65 exempt 8 oz spray Works on all firearm platforms. This is a solvent only, not a lubricant, so pair it with a CLP or dedicated lube to finish the job.
