How to Whiten a Cotton, Nylon & Spandex Blouse

White clothes are hard to keep white. They act as magnets for spaghetti sauce or naturally yellow over time.

White clothes are hard to keep white. They act as magnets for spaghetti sauce or naturally yellow over time. If you have a cotton, nylon and spandex-blend blouse that is looking a bit dingy, avoid chlorine bleach if you can. It can cause the fabric to become discolored or even deteriorate the fibers. Use other common household products to whiten the blouse.

  1. Put the blouse inside the washing machine. Set the washing machine to the "cold" water temperature.

  2. Add the recommended amount of laundry detergent and 1 cup of hydrogen peroxide. In a front-loading washer, put the peroxide in the bleach dispenser. Run the blouse through a complete wash cycle.
