Your toddler just launched a cup of purple grape juice at your white shirt. How to clean the stain without making it messier? Some pointers:
Coffee, tea, grape juice: Stains produced by these tannins don't react well with soap. Try sponging with cold water, then pretreat with Shout before washing.
Butter: Dissolve with a few drops of non-acetone nail polish remover; rinse in cold water.
Egg: Use cold water. Never use hot water on protein stains (including blood).
Ink, Sweat: Take items to dry cleaner!
