Lay the dye transfer stained clothing on a flat work surface with the stained areas facing up. If the garment isn't fresh from the wash machine, dampen the stained area to moisten the fabric.
Pour heavy-duty laundry detergent over the dye transfer stain to cover the stain. Rub the detergent into the stained fabric and allow it to sit for 1 or 2 minutes.
Rinse the heavy-duty laundry detergent off the fabric with cool water. Fill a bucket with 1 gallon cool water and mix in 1/2 cup of all-fabric bleach. Soak the dye transfer stained garment in the bleach solution for 30 minutes to remove the stains.
Wash the garment according to directions on the care label. Use heavy-duty laundry detergent and all-fabric bleach in the wash cycle to remove the remainder of the dye transfer stain from your colored clothing.
Check the garment before placing it in the dryer. If any dye transfer stain remains repeat these steps until it's removed before drying.
