So basically, this shirt has to be washed separately for the rest of it's life?
I have one of those baseball/athletic shirts, like the OP described. No way was I putting it with my whites. I have to do my laundry at a laundromat & wasn't going to waste $2 each time to wash one shirt in a separate washer. I put it in with my darks. The sleeves are still dark. The white is dingy.
