in an attempt to salvage my beloved beige sweater...

• try moistening the area with a solution of 1 teaspoon liquid laundry detergent (that is safe for wool) and 1 cup warm water
• cover with an absorbent pad dipped in the solution and wrung nearly dry
• let it stand for 30 minutes, adding enough solution to keep the area warm and barely moist
• when stain is removed, flush thoroughly with water and allow to dry

this shall probably not be successful.
