I'm not entirely sure this is the place for general questions about clothing care, but I figured I might as well take a shot given that this board involves fabric care.
I like collecting and wearing football jerseys, but I've been running into an issue with the numbers on some of mine. They've been wrinkling up in the wash - I think I either used too much detergent or washed them in a machine that wasn't clean - and it results in this unsightly, uneven look. The problem is, all new NFL jerseys are made from recycled polyester, so they resist ironing since they don't absorb moisture. I've used a pressing cloth and low heat to keep from burning them, but the wrinkles don't come out no matter how gentle I am with them.
Is there any way to treat recycled polyester so that it looks like new again? Jerseys aren't cheap so I'd rather not have to drop another $150 on stuff I've already bought.
