I wore a deep purple polo shirt today during my state's continuing attempt at mimicking some tropical paradise's mugginess and blisteringly hot days. Imagine my surprise when I noticed spotty discoloration under the arms where I apply deodorant. Is there a way of removing these stains and salvaging the shirt? (The shirt is a 50% polyester/50% cotton blend.) No dyes were transferred to my skin and it has not happened to any other shirts of similar blend.
Many thanks.
