Clean spills on tile as quickly as possible. Soak up spilled oil with paper towels. Remove all you can by blotting. Do not rub or scrub as this will spread the oil stain.
Sprinkle dry corn meal or baking soda on the oil spill and allow to sit for 24 hours. Remove the absorbent material by vacuuming. (Put a chair or stool over the spill to prevent someone from stepping on the spilled oil. Oil on tile is very slippery and can cause a bad fall.)
Wash the area with a grease cutting dish washing liquid. Pour the 1/4 cup of the soap on the stain, scrub with a soft, non-abrasive brush. Rinse with water and blot dry with paper towels.
