how do you whiten up old bras and make them look new again?
Wash them in amonia
Try using an oxygenated powder like OxyClean or Awesome Orange in your wash (along with regular detergent). Add one scoop to your washload.
Brenda: Soak overnite in OxiClean. (Stir occasionally)
Try soaking them in Mrs. Stewart's bluing liquid. It's been used since 1883.
Fill washer with oxiclean and HOT water. Let soak over night.
