If color has crocked or rubbed off, the garment should be washed or drycleaned according to the care label to remove any loose dye from the remaining fabric.

Benzoyl peroxide, an ingredient in some acne medications and skin cleansers, can cause color loss or color change. During storage, acid gases in the atmosphere can react with some dyes.
