Create a mixture of one-quarter cup white vinegar, one tablespoon table salt, and one-quarter cup hydrogen peroxide. Stir the ingredients until they are thoroughly mixed.
Place the affected synthetic garments into the washing machine. Pour the white vinegar and peroxide mixture directly over the garments.
Run the machine on a cold water setting and allow it to complete all of its cycles before continuing.
Smell the clothing and if the bleach smell is eliminated, dry the clothing according to the label’s directions. If the unwanted smell persists, mix an additional batch of the bleach-odor eliminator described in Step 1 and wash the clothing again.
