Get a bar of Ivory soap(not liquid). Wet the spot and vigorously rub soap into spot. Leave in a little while. Rinse with water and dry(can us a hair dryer). If you have a ring type stain after treating - that's a soap ring - just rinse again. I find the Ivory takes out just about all stains even old ones. Old ones may need 2 treatments. On clothes, I rub in the Ivory and leave it on the spot until I get around to washing it. It doesn't hurt to have the soap dry on the cloth.
A friend taught me this many, many years ago and I've always used it with great success.
Good luck. :-)
