For chocolate, scrub the stained area immediately with ammonia, then wash as you normally would.
For egg stains, scrape off the excess with a dull knife, then soak the stain in cold water. Launder as you usually would. If the article requires dry cleaning, sponge the stain with cold water and take it to the dry cleaner right away.
Fresh coffee and tea called for the “hot waterfall” approach. First, stretch the stained part of the fabric over a bowl, as if you were putting a head on a drum, and secure it with a rubber band. Then pour boiling water over the stain from a height of two to three feet. Be careful not to burn yourself! Wash the article as you normally would, using a small amount of bleach if the fabric can tolerate it. The “hot waterfall” also works to loosen fruit and berry stains. It works with red wine if you first sprinkle a little salt on the stain.
After a wine spill, blot up as much of the wine as you can, then rinse with cool water or club soda. Sprinkle a little salt on the stain, and create a paste of salt and water. Then, if the fabric will stand it, pour boiling water through the stain with the cloth stretched over a bowl or bathtub. For tough stains, try blotting the stains with one of the following: 1/3 cup vinegar in 2/3 cup water; 2 tablespoons ammonia in 1 cup water; or alcohol, either straight or mixed with an equal amount of water. Rinse well and then launder as usual. In some cases, you may have to use an enzyme detergent to remove wine stains.
If spilled beer has dried onto clothing or tablecloths, mix a solution of equal parts vinegar and dish washing liquid, then sponge it onto the stain. Rinse with warm water and launder as usual. Tips from the “The Old Farmer’s Almanac“
