@jeeves_ny: This is a 4th generation dry cleaners guide to remove butter, oil, grease, and any fat based stain: 1) Pretreat with a surfactant like dish soap or liquid laundry detergent (2-3 drops at max) 2) For larger stains try diluting 2-3 drops in some water and spraying on. You don't want to have oversudsing issues. 3) Inspect before tumble drying. Hot air will set a stain. 4) Repeat if needed 5) If any color remains, treat with oxygen bleach like OxiClean or hydrogen peroxide.
