For cotton and polyester: Make a paste of lemon juice and salt. Be careful—this may cause discoloration on some fabrics. Cover stain with paste and let sit 15-30 minutes. Rinse. Machine wash according to garment care label.
For washable silk and wool: Using an eye dropper, apply a half-vinegar half-water solution to the stain. Let sit 10 minutes. Flush with water. Take garment to a dry cleaner to completely remove stain.
