To remove color stains from clothes after drying, rewash the clothes with an oxygen based bleach or Oxiclean and detergent.
You can also soak the clothes in a diluted bleach solution after drying to remove color stains from the clothing.
If the color stain is stubborn you may need to pre treat the color stain with some liquid detergent or stain remover and allow it to sit for 30 minutes to an hour or so before rewashing it.
When you have color stains on clothes after drying you should wash them again using a non chlorine oxygen based bleach and your regular laundry detergent.
If the rewashing of the clothes does not remove the color stain, you can soak the clothes in a solution of oxygen based bleach along with cold water for several hours and then rewash the clothes again.
For more stubborn color stains on your clothing you can apply some liquid laundry detergent or stain remover to the color stain and allow it to sit for 10 to 15 minutes and then rewash the clothes in the washing machine.
Rubbing alcohol can also remove most color stains by using a white cloth with some rubbing alcohol and blotting the color stain.
If the rubbing alcohol does not work to remove the color stain you an also use some ammonia but you should ventilate the area well when using ammonia.
You can also create a paste of baking soda and water and apply it to the color stain and let it dry before you wash the clothing again.
If it's a fresh color stain you can also try pre treating the area with a mixture of dish soap and detergent.
