How do you whiten cotton/polyester blends?


Cotton/polyester blend white fabrics can be safely washed with Clorox® Disinfecting Bleach on an on-going basis. Always wash whites in hot water – or the hottest water recommended on a care label. It’s also important to use enough bleach. In a standard washer, use ⅓ cup Clorox® Disinfecting Bleach for normal size loads, and up to ⅔ cup for extra-large or heavily soiled loads.  For best results you (again in a standard washer) dilute the measured bleach in 1 quart of water and add it to the clothes washer 5 minutes after the wash cycle has begun.

If you have a HE washer, fill the bleach dispenser to the “max-fill” line. For heavily soiled laundry, consider washing two smaller loads.

For extra whitening or heavily stained items, use a bleach soaking solution of 1/4 cup Clorox® Disinfecting Bleach per gallon of water.  Fully submerge the item for 5 minutes, then rinse.  Finish by washing the item in hot water, using detergent + ⅓ cup Clorox® Disinfecting Bleach.
