In one sentence, describe what the following article is about:

Place the whites in a large sink or bathtub. Add 1 cup (235 mL) of white vinegar. If the clothing labels state bleach is okay, you can substitute the vinegar with ¼ cup (60 mL) of non-chlorine bleach. Add one gallon (3.8 liters) of cool water. Soak for 30 minutes. After you have soaked the white clothing for 30 minutes, rinse with cool water. Then place the laundry in the washing machine. Add detergent and wash with cool water. Air dry the clothing. If soaking and washing the white clothing in vinegar or bleach does not remove the dye, you can try a color remover like Rit Color Remover or Carbona Color Remover. Mix the product with water according to package directions, and then soak, rinse, and launder the clothing. You should only use color remover on all-white clothing as this harsh product will strip all dyes from the fabric.

Summary:
Soak white clothing in bleach or vinegar. Rinse and launder. Try a color remover.
