Should your clothes begin to appear yellow or gray take your bleach to the toxic dump. Bleach turns whites a dingy color with repeated launderings. Fill the washer will cool water, add 2 cups hydrogen peroxide and half the normal amount of detergent. Add the clothes allowing them to soak for 30 minutes. Continue the wash cycle.
If after 30 minutes the clothes still appear yellow, add more peroxide to the water and continue soaking for another 30 minutes.
