A6: If your rubber mat is covered in oil, you should try cleaning it immediately before the oil seeps into the pores of your flooring. You can use a fabric that's soaked with rubbing alcohol to blot up these oil stains. Blotting them will help reduce the mess by pushing the stain and any excess oil away from the area. You should be able to remove large oil stains this way, but you may not be able to remove them all.
