How Do You Set Dye in Blue Jeans?

To set the dye in your blue jeans and prevent bleeding, wash your jeans in cold water with white vinegar. This process takes from the length of one wash cycle to overnight. You need cold water, white vinegar and a washer to complete the process.

  1. Avoid wearing your jeans after first purchasing them

    Wash your jeans immediately after purchasing them. This helps to set the dye, and prevents you from getting blue on furniture and other clothes.

  2. Wash your jeans

    Turn your jeans inside out before washing them. Fill the washing machine with cold water to prevent your jeans from shrinking. Hot water can cause the material to shrink and is harsh on dyes. Add 1 cup of white vinegar to the water. Place the jeans in the washer. Run the jeans through the wash cycle. Repeat this process several times if necessary.

  3. Soak your jeans

    If the dye in your jeans is still bleeding, soak the jeans in a water and vinegar solution overnight in a bathtub. After soaking, run them through a wash cycle.

  4. Dry your jeans

    Never put your jeans in a dryer because this destroys the shape of the pants. Hang them up on a line to air dry.
