If your laundry has turned pink or blue because you've added a garment of the wrong color by mistake, follow this hint. Remove the offending article, and put all of the affected items back into the
machine.
Immediately run the washing machine through another complete wash cycle. Quick action may be enough to wash the color out.
For whites, RIT Dye makes a Color Remover which works wonders for returning items to white. Beware that it turns everything to white, so only wash items in the Color Remover if you are expecting solid white items in return.
