Cotton/ Polyester blend caps
Hand washing may be a bit time consuming but it is the best way to take care of your cap.
Start with the sweatband: Brush a small amount of stain remover onto the sweatband and let it rest for 15 min.
After that, continue to brush with a mixture of detergent and water.
Wash the cap with a load of similarly colored clothing on the delicate cycle using cool water. Do not use chlorine bleach even on a white cap. If the cap looks dull and you wish to brighten the colors, mix a solution of oxygen-based bleach and warm water following package directions. Completely submerge the cap and allow it to soak for at least four hours or overnight.
