Spots on bike bar tape after wet ride I recently went on a ride which partly involved a light rain and after that I noticed that among other things there were a lot of mud colored spots on my bar tape. I presumed it was grit and mud stuck onto the tape (it looks almost painted on though, very little if any 3d shape to them), and tried to pry them out with a needed, but it felt like all i did was tear a bit of foam. Does anyone know what this is? Would this come off with some soap?

I cant be 100% sure it wasnt there before, but the bar tape was recently replaced by the prev owner.
It's almost certainly cork that is used in the bar tape for its vibration damping and sweat absorbing properties.

It's clearly visible in this promotional image for Cinelli tape:
