Washing Machine 3

Bleaching jeans is a popular way to achieve a faded, distressed look. Whether you’re trying to revive an old pair of jeans or experiment with a new style, this guide will provide a comprehensive walkthrough on how to lighten jeans with bleach in the washing machine.


To lighten jeans with bleach in the washing machine, first wash your jeans and prepare your workspace. Fill the washing machine with cool water and add 1/2 cup of liquid bleach. Soak the jeans for 20 to 40 minutes, then drain the machine. Run a regular cycle with warm water and mild detergent, followed by a rinse in cold water. Finally, allow the jeans to air dry. Always remember to use protective gloves and ensure proper ventilation when handling bleach.

Preparing Your Jeans for Bleaching

Before starting, ensure your jeans are freshly washed and free from any dirt or chemicals that might interfere with the bleaching process. You should also protect your work area by laying newspapers or plastic tablecloths on the floor around the washing machine to prevent bleach spills from staining surfaces. Always remember to wear protective gloves when handling bleach and ensure proper ventilation in your work area.

Choosing the Right Bleach

When it comes to bleaching jeans, the most common types of bleach are chlorine bleach and oxygen bleach. Brands like Clorox┬« Disinfecting Bleach with CLOROMAX┬« are often recommended. However, always check the label to ensure it’s suitable for denim before use.

The Bleaching Process

Follow these steps to bleach your jeans:

  1. Fill the washing machine with cool water and add 1/2 cup of liquid bleach.
  2. Place the jeans in the washing machine and let them soak for 20 to 40 minutes, depending on how light you want the denim to be.
  3. After soaking, drain the washing machine.
  4. Run the jeans through a regular cycle in warm water with a mild detergent.
  5. Rinse the jeans in cold water after 5 minutes, then wash them without detergent.
  6. Allow the jeans to air dry.

Remember, bleach can weaken the fabric, so avoid overexposing the jeans to bleach.

Post-Bleaching Care

After bleaching, rinse your jeans thoroughly in cold water to remove any remaining bleach. You can then neutralize the bleach by submerging the jeans in a hydrogen peroxide solution until the fabric stops fizzing. Rinse again, remove excess water by rolling the jeans in a towel, and then hang them to air dry.

To maintain the lightened color, wash your jeans with cold water and a gentle detergent. Avoid using bleach or harsh chemicals that could alter the color. Additionally, air-drying your jeans instead of using a dryer can help preserve the color and prevent further fading.

Risks and Precautions

Bleaching jeans in a washing machine can pose potential risks, such as fabric damage, uneven discoloration, and weakening of fibers. However, these risks can be mitigated by properly diluting the bleach, testing the fabric before use, pre-washing jeans, using bleach alternatives if necessary, and ensuring to rinse thoroughly after bleaching.

Bleach Alternatives

If you’re wary of using bleach, there are several alternatives available. Hydrogen peroxide, baking soda, vinegar, and lemon juice are all gentler on fabric and more environmentally friendly. The process for using these alternatives is similar to the bleaching method, but always remember to test on an inconspicuous area first.

In conclusion, lightening jeans with bleach in the washing machine is a simple process that can transform your denim. By following the correct procedures and taking necessary precautions, you can achieve a fresh, new look for your jeans.
