What makes my white clothes look dingy, gray, or yellow when Ive just washed them?
White clothes should be washed with only other white clothes. Cottons and whites that do not shrink can be washed in hot water, any good detergent, and liquid bleach. White clothes that are nylon or synthetic material can be washed in detergent and non chlorine bleach or a little ammonia. If they do not get white after washing like this, maybe you have hard water. Try adding a bit more detergent or water softener. Also a blue type fabric softener might help.
