Question

How do you whiten cotton/polyester blends?

Answer

Cotton/polyester blend white fabrics can be safely washed with Clorox® Regular Bleach2 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:  3/4 cup Clorox® Regular Bleach2 for normal size loads, and up to 1 1/4 cups for extra-large or heavily soiled loads.  In a standard washer, delay bleach addition for best results by diluting 3/4 cup bleach in 1 quart of water and adding it to the clothes washer 5 minutes after the wash cycle has begun.  If you have a HE washer, with a small-capacity bleach dispenser, consider washing two smaller loads if you have heavily soiled laundry.

For extra whitening or heavily stained items, use a bleach soaking solution of 1/4 cup Clorox® Regular Bleach2 per gallon of water.  Fully submerge the item for 5 minutes, then rinse.  Finish by washing the item in hot water, using detergent + 3/4 cup Clorox® Regular-Bleach.
