Let’s look it up!  It seems that the best way to clean up an oil spill of any kind, including petroleum and vegetable oil, is to soak up as much of the spill material as possible by using a non-flammable absorbent material, like a towel or rag.  Pick up any loose debris or trash and take it to a trash can, because it can contain toxic chemicals.  Avoid washing oil away with water as this can spread it further, irritate humans and damage wildlife.

The best way to clean up petroleum oil when it's spilled on your skin or clothing is to rinse with dish soap and warm water, and seek medical attention if the spill penetrates your skin.  In the case of a larger spill, contact your local environmental authorities for disposal recommendations.  Do not make a fire or use flammable solvents to try to clean the spill
