Ketchup and mustard belong in and on your food, not your clothing! We know that but sometimes drips and spills happen. These both contain strong pigments that can permanently dye your clothing. If you happen to over-fill your burger or dog and this happens to you, first, scrape off as much as you can of the condiment. Now cover with an artificial sweetener such as Splenda. Wait a few minutes then brush off and flush with water. The fine granules in the artificial sweetener will soak up the moisture from the stains. Wash your garment as usual.
