The exact process to remove dye stains from clothing depends on the type of cloth and color of the dye. All fabric and dye combinations involve soaking for an extended period of time in detergent or bleach; follow the manufacturer's care instructions when choosing the cleaning agent.
Oxygen-based bleaches are safe and effective for most fabrics and dye stains. This form of bleach is safe for colored and patterned fabrics. Adding a cup of distilled white vinegar to the washing solution can increase its effectiveness on difficult stains. This process is less effective on red dyes and white fabrics than other colors of dye and types of fabric.
Dye removers such as Carbona Color Run Remover are also effective on colored clothing. Dissolve one packet of dye remover in 4 gallons of hot water, and soak until the dye stain is gone. Wash the clothing normally after the soak. These steps can be repeated if the stain persists. Color removers are effective on difficult to remove colors such as red.
Chlorine bleach-safe white fabrics can be soaked in a solution of chlorine bleach and water. Good Housekeeping recommends using 1/4 cup of chlorine bleach per gallon of water. Wash the clothing normally after 30 minutes of soak time.
