FrogLube CLP is a cutting edge biodegradable lubricant made from "USDA Certified Food-Grade" materials. 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 by absorption deep into the pores. Using FrogLube CLP results in a durable dry slick wax-like surface that reduces friction, eliminates fouling, and destroys rust. FrogLube CLP is safe for plastic, urethane, nylon, and wood. FrogLube CLP will give your weapon many extended years of service. FrogLube CLP will not harm the environment. It can be disposed of without the need for prohibitive HAZMAT controls. FrogLube CLP contains no petroleum or water and has a pleasant mint smell. This version of FrogLube CLP is available as a liquid in a 4 oz or 8 oz bottle.
