If the bra is heavily darkened, increase the time to 2-3 hours. After that, wash it with powder.
If the brae there are elements of decor of a different color, you can also use stain remover. It will refresh the color white, but at the same time will not spoil the bright colors of the pattern or Ruche. Add it with each wash, if you have poor quality tap water.
