Mission Control Concrete Stain Remover is a 32 oz professional formula built for one job: cutting oil and grease off porous concrete. Garage floors, driveways, workshop slabs, patios, sidewalks. This concrete oil stain remover works best on fresh oil and grease. It cuts and lifts stains from the surface and rinses clean. Treat spills and drips as soon as possible. The sooner you treat a stain, the better the result. This is not for old, setin stains. Oil that has soaked in and set over time will not come out. Treat spills while they are still fresh. Easy to use. Apply liberally to the stained area. Let it sit a few minutes. Agitate with a stiff bristled brush. Flush with clear water. For heavier spills, apply again as needed. No mixing, no pressure washer required. Works as a driveway oil stain remover, garage floor degreaser, concrete degreaser, and concrete cleaner outdoor. Built for unsealed concrete and masonry. Test first on a small area. Not for asphalt, natural stone, sealed or coated floors, or wood. Built for homeowners and contractors maintaining bare concrete. Made in USA.
