How do I clean stains on my concrete driveway / garage floor?
Saturate the stain with Oil Eater full strength. Allow Oil Eater to penetrate the stain for about 10 minutes. Agitate the stain lightly with a broom or brush. Rinse the surface thoroughly or soak up with a shop rag.
Uncoated concrete is very porous; it almost acts like a sponge. If the stain is not completely gone after one application, wait 24 hours and repeat the process. This allows the concrete to “breath” bringing what was soaked in up to the surface. Old or deep stains may need multiple applications. Keep each application at least 24 hours apart to be most effective.
