For color-fast, non-bleachable fabrics
Mix a solution of drug-store regular strength (20% volume) hydrogen peroxide and water. The solution should be very weak - 1 part hydrogen peroxide to 9 parts water. Hydrogen peroxide is a bleaching agent and should not be used at full strength on colored fabrics.
Soak the stain in the solution for at least two hours. Rinse the clothing in cool, clean water and then wash as directed on the clothing label using detergent.
For white, bleachable fabrics
As soon as possible, wash the fabric as usual using chlorine bleach and regular detergent.
For dry clean only fabrics
Mix 1 tablespoon borax with 1 pint of lukewarm water. Use a sponge to apply the borax solution to the stain. Do not saturate the stain, simply sponge on solution and blot away curry with a white absorbent cloth or paper towel. When the stain lifts, sponge the area with cool, clean water and allow to dry. If stain remains, take garment to a professional dry cleaner and identify the stain.
