Serious, Cleaning Power
For more than 50 years, Gunk®, the industry leader and most trusted name in cleaning and degreasing, has provided optimized solutions to tackle the toughest grease, grime and gunk throughout the garage.
Gunk® originally started as a degreaser called Engine Brite and was manufactured by Gunk Laboratories. As the story goes, the developer of Engine Brite was a motorcycle enthusiast who was asked by a fellow rider to “give me some of that gunk to grease my bike.” From then on, the product was referred to as Gunk. In 1959, RSC became the US and worldwide distributor of Gunk-Engine Brite products and, in 1976, RSC acquired the brand from Gunk Laboratories.
Gunk® is the industry leader and most trusted name in the engine cleaning and degreasing category. As the leader, we provide powerful cleaning and degreasing solutions aimed at tackling the toughest grease and grime on automotive parts and around the shop or garage.
