cleaning up an old hat

I have this vintage Hanshin Tigers hat. I'm gonna sew the strap back on today. The thing has a lot of discoloration and spots on it. Any suggestions for removing them? The outer lining is polyester, so is the inner lining. The reinforcement on the inside of the brim is polyethylene.

as its pure white you could try spot bleaching, if a more general scrub doesn't get it out

I’d just try an oxi clean soak first and see what happens

I could try that. Just use the quantities listed on the container of oxiclean, or do I wanna do a higher amount of the cleaner

Just follow the pre soak instructions on the tin first
