Adam’s Concrete Cleaner is a readily biodegradable powder, heavy-duty cleaning detergent for removing stains caused by silicones, oils, grease, or dirt on your concrete, driveway, sidewalks, garage floor or other exterior, porous and non-porous hard surfaces. Adam’s Concrete Cleaner won’t dissolve, embrittle, or soften concrete, ceramics, or epoxy surfaces. This formulation is non-caustic, non-butyl, does not contain any chlorinated solvents, and also doesn’t utilize a dye so there’s no chance of staining surfaces or resembling a neon-colored solution, such as an anti-freeze, as it is rinsed into storm drains or sewers. Not for use on fabrics, plastics, or metals.
Is ok but not the best on old oil stains
