How to Bleach Khakis White

Bleaching khakis can be a very complicated process because of the different fibers used to make khakis. Though the color khaki is so often used to describe a kind of pant that it has become a catch-all phrase for the garment, it is still a color and not a fabric. Khaki-colored clothes are made from all kinds of natural and synthetic fibers, some of which cannot be bleached. If the khakis are made from cotton, wool or a blend of both, it is possible to bleach them completely white. Cotton blends with nylon or silk cannot be bleached.

Add the garment to the pot until it is white. It will take between 16 and 24 hours to change color.

Step 1

Mix equal parts of bleach and warm water in a pot big enough to hold the garment. The solution cannot exceed 50 percent bleach, or it will damage the fabric.

Step 3

Remove the garment from the bleach mixture, and neutralize it in a mixture of warm water and bleach stop.
