Muscle Grease

Muscle Grease


Castle® Muscle Grease™ takes over as a lubricant where lithium and calcium grease leave off. The aluminum complex base of Muscle Grease™ enables it to excel in heavy load, extreme pressure situations and over a wide range of temperatures (0° F to 350° F) without melting, hardening, or thinning. It is 100% waterproof and resists corrosion from acids, alkalis, and salt. Muscle Grease™ sprays like a liquid to penetrate, and then sets up as durable grease.
