Fill the washing machine with hot water about half full. Add 1/2 cup of bleach to the water and allow the machine to agitate for a minute to mix the solution.
Add the clothing into the washing machine. Allow it to sit for 30 to 60 minutes.
Add laundry detergent per the instructions on the packaging for your load size. Operate the washing machine through a normal cycle.
Rewash the garments with mild detergent in warm water to remove any remaining bleach residue.
Repeat the process if the clothing still maintains some of the dye.
