Try the following techniques until one succeeds in removing the stain.
1. Remove excess food as soon as possible.
Use a spoon or a blunt knife to scrape the stain. The longer a stain sets, the more difficult it is to remove.
2. Make a detergent solution.
Mix one teaspoon of clear, mild liquid dishwashing detergent with one cup of lukewarm water. Do not use detergent that contains bleach.
3. Apply the detergent solution to the stain.
Do not rub the stain. Work from the edge of the stain in, gently blotting.
4. Rinse the stain with cold water and blot dry.
If the stain comes out, go to step 14.
5. Make an ammonia solution.
If the detergent solution does not work, mix one tablespoon of household ammonia with ½ cup of warm water.
6. Apply the ammonia solution to the stain.
Blot the stain. Do not rub.
7. Rinse with cold water and blot dry.
If the stain now comes out, go to step 14.
8. Make a vinegar solution.
Mix 1/3 cup white vinegar with 2/3 cup cold water.
9. Blot the stain with the vinegar solution.
10. Rinse with cold water and blot dry.
If the stain has disappeared, go to step 14.
11. Apply commercial enzyme detergent.
Enzyme detergent is available in grocery, drug, and hardware stores. Blot the stain.
12. Rinse the area with cold water.
13. Blot dry.
Place a ½-inch-thick pad of white paper towels over the stained area and weigh it down with a flat, heavy object—a thick book works well. Change the absorbent pad until the transfer of the stain is no longer visible on the pad.
14. Launder according to manufacturer’s label.
