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.

Instructions

  1. Wool or Cotton-Wool Blend Khaki

    • 1

      Dip the garment in a pot of boiling hot water with 1/2 a teaspoon each of the dye pre-wash and soda ash.

    • 2

      Mix 7 1/2 tablespoons of soda ash, 3 cups of hydrogen peroxide and 1 teaspoon of dye pre-wash in another pot with 2 quarts of tepid water.

    • 3

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

    • 4

      Mix a gallon of warm water and 1 1/4 cup of distilled white vinegar, and immerse it in for 10 minutes.

    • 5

      Rinse the garment and dry.

    Pure Cotton Khaki

    • 6

      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.

    • 7

      Add the garment to the bleach mixture, and let it sit until it is white. The fabric will turn white in the bleach and water mixture almost immediately.

    • 8

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

    • 9

      Rinse the garment and dry.
