How to remove sweat stains from a polyester /wool tie?

Question

Yesterday I asked this question but I didn't include some facts. It is a uniform tie dark blue made of 55% polyester and 45% wool. I know they have to be dry cleaned but that doesn't always get those white sweat stains out. I thought about using scotchguard to repel the sweat. Any suggestions on that and a way to pre treat it before bringing it to the dry cleaner. Thanks.

Answer 1

Just sweat all over the rest of it so it's consistent...

Answer 2

dry cleaner is best solution.
