White jackets can look smart and stylish, but even the smallest stain or smudge will stick out like a sore thumb. A dirty white jacket will often stay that way after being washed with regular detergent, with the stains only fading or even refusing to budge at all. A surefire way to clean a white jacket is to use a household bleach. Bleach is safe for use on all cotton and most synthetic fabrics and will make your white jacket bright and clean as snow.
Things You'll Need
Check the tag on the jacket to see if there are any instructions against machine washing. Unless the jacket is leather or down, it should be able to go through the wash just fine. Place the jacket in your washing machine, select the water temperature listed on the tag, and start it. Most white loads require hot water. If there is any particular area that requires special care, you can spot treat it with a bleaching pen.
Wait until the jacket is completely submerged in water before adding the bleach to avoid spotting. Add the bleach to the water, using the directions on the back of the bottle to determine the amount needed. Shut the washer and allow the cycle to complete.
Hang the jacket up and allow it to completely dry.
