Rub some cornstarch into the stain with an old toothbrush and let sit for awhile. Cornstarch will absorb oil. Brush off. Repeat if needed. Or, put a towel behind spot. Rub spot with a cloth which has been wet with warm water, wrung out and rubbed across a bar of Ivory soap. Rinse with a clean, wet cloth. You can then blot wet spot with a dry cloth and let finish air drying. If a heavy or old spot you can let Ivory soap sit on spot for awhile(does'nt hurt if soap dries). I have used this method of spot removal for many years on all kinds of stains and it works wonderfully.
