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 contains no petroleum or water and has a pleasant mint smell. This model comes in a 4 oz bottle.
