After golfing on two different occasions and at different locations, I noticed the stains on these garments (first the shorts and then the shirt). They are near seams (pocket on shorts and the sleeve cuff and collar for the shirt). I didn't notice them until a day or two after so I'm wondering if they appeared later. I have no idea what they could be other than maybe some reaction to sunscreen? I've tried an OxyClean soak and wash but that made no noticeable difference.

Does anyone have a similar experience or have ideas on how to remove them? Thanks in advance!
