My friend is working on this problem and has solved it but I don't think we are going to go through with a formulation as he can't convince management it would be a money maker.

All I can say is try washing your athletic clothes in Head & Shoulders. The regular kind with Zinc Pyrithone. It has antifungal and antibac properties. Only need to do it about once a month. Helps with malodor issues in the front loaders too.

Try it and thank me later.
