Wine
Murphy’s Law more often makes wine (especially red) end up on your blouse than inside your glass. Here are some tips on how to get rid of such stains:
For fresh stains: Soak a cotton pad in a blend of vinegar and hot water. Then rub the stain. For old stains: Mix about 0.03 ounces of citric acid with 1 glass of water. If the stain is still visible, rub it with a hydrogen peroxide and ammonia solution (put 1 teaspoon of each substance into 1 glass of hot water).
