Problem: A load of whites ruined by a rogue red sock

Solution: To undye a load of laundry, rewash it with chlorine bleach if the clothes can take it (check the care labels) or a color-safe bleach if the items are more delicate. But don't expect a miracle with color-safe bleach: Brian Sansoni, spokesman for the Soap and Detergent Association, in Washington, D.C., says color-safe bleaches "work best on maintaining whiteness, not restoring it."
