Froglube Liquid is a cutting edge Bio-Based lubricant made from "USDA Certified Food-Grade". All ingredients are produced in the USA using a proprietary formula. It is a non-toxic substance that dissolves carbon on contact. It has a heavy specific gravity, which enables it to 'season' the metal through absorption deep into the pores. Using FROGLUBE results in a durable dry slick wax-like surface that reduces friction, eliminates fouling, and destroys rust. FROGLUBE is safe for plastic, urethane, nylon, and wood. FROGLUBEwill give your weapon many extended years of service.
