Superclean

Superclean (formally SuperClean Brands, LLC, based in Eagan, MN) has built a following among automotive enthusiasts and general consumers on the strength of a single concentrated degreaser that spans everything from engine-bay cleanup to laundry pre-soak. The product's purple bottle is a familiar sight in auto-parts stores and has earned a strong repeat-purchase base among people who want one bottle that covers most of what they clean.

The brand's formula is water-based and phosphate-free, which it markets as a differentiator from solvent-heavy industrial degreasers. SuperClean Brands also makes a foaming degreaser variant (same base formula, aerosolized) and a wheel cleaner under the same brand umbrella.
