On my new Nike Roger Federer caps there are, after some intensive hours of tennis for the last 2 weeks, areas of sweet remains. Looks dirty, looks ugly. How do I wash or clean these caps? Can I put them in the washing machine?
We have 4 family members that go through tech wear. So we have the sports detergent and we have "sports load" for the washer. My wife has various size nets to put delicate or odd shaped pieces into. I toss my hats in there. Use permanent press dry if we're in a hurry or we have a rack to hang our sports wash to dry.
