Allow the absorbent to sit for several hours or overnight; attempting to scrub a wet stain almost always results in the oil spreading and creating a larger, more diffuse mark.

Common household agents like dish soap combined with warm water work well on fresh stains, but older, set-in stains often require a stronger alkaline solution. For best results, allow the cleaning solution to soak for 10 to 15 minutes; this dwell time gives the alkaline agent the opportunity to saponify the fats, turning them into a water-soluble substance that can be rinsed away.
