White Brite and it sells for about 4 dollars for a 22 oz bottle. Followed the instructions on the bottle for pre-soaking, mixed 1/2 cup White Brite in a plastic container with 1 gallon of warm water and let soak for about 20-30 minutes, then wash as usual.
The Only Spot Remover You'll Ever Need- One part Dawn dishwashing liquid mixed with two parts HYDROGEN PEROXIDE. Pour the mixture directly on the stain, and watch it disappear like MAGIC. (Particularly tough stain, can add baking soda & scrub.)
Place a dishwasher-safe cup filled with plain white vinegar on the top rack of the dishwasher. Using the hottest water available, run the dishwasher through a cycle. The vinegar will help to wash away the loose, greasy grime, sanitizes, and helps remove the musty odor. Next, sprinkle a cupful of baking soda around the bottom of the tub and run it through a short cycle. The baking soda will help freshen and removing stains. Great for when you move into a new place
