Greased Lightning is a decades-old American household-cleaner brand best known for its bright yellow Super Strength Multi-Purpose Cleaner & Degreaser, a fixture on grocery, hardware, and big-box shelves. The line leans on high-alkaline surfactant chemistry pitched at the toughest household jobs — baked-on cooktop grease, garage floor oil stains, grills, and general degreasing — rather than at automotive detailing specifically.
The brand is manufactured by HomeCare Labs, Inc. (Lawrenceville, Georgia), a subsidiary of KIK Consumer Products, one of North America's larger contract and private-label household-chemical manufacturers. Because Greased Lightning is a general-purpose cleaner rather than a purpose-built auto product, CarCareTruth evaluates its fit for engine-bay and automotive degreasing on the product's own SDS chemistry and label surface restrictions rather than on any auto-detailing marketing claim.
