How to Use Chlorine Bleach to Clean Clothes. Chlorine bleach, used to boost the cleaning power of regular laundry detergents, is ideal for removing tough stains and occasionally whitening fabrics, but improper and long-term use may take its toll on fabric life and colors. Pretest on the garment for color- and fabric-steadfastness before using it on a stain.
Read the garment's care label and make sure that it does not warn against using bleach.
Dilute the bleach according to the directions on the product's label.
Begin the wash cycle, adding laundry detergent as directed.
Add bleach to the washer 5 or 6 minutes later, making sure that the washer is full with the soapy water.
Launder as usual.
Watch closely for color change; rinse immediately if you see any sign of dye change.
