Often used on equipment in the mining, oil, and gas industries, these citrus-based solvents remove carbon black, crude oil, tar, asphalt, and grease. With no flammable or harsh chemicals, they can be rinsed away. They are also NSF registered C1 for use in non-food-processing areas within food-processing facilities. Unlike other solvent-based degreasers, they mix with water so you can dilute them, or you can use them full strength.
