As soon as possible, flush the stain with cool water. Use a pre-treater on the stain or rub in a bit of extra liquid detergent. Launder as usual.
If the stain remains, do not dry the clothing. Soak in an oxygen-based bleach solution like OxiClean to remove the remaining stain. Launder again.
If the garment is dry clean only, point out and identify the stain to your professional cleaner. If you are using a home dry cleaning kit, be sure to treat the stain with the provided stain remover before putting the garment in the dryer bag.
