Problematic Stains

[DonBowl]

Hello, I believe i'm in need of some guidance here.
I'm pretty new to properly taking care of hats.

This Dobbs Newsboy cap I own got a small blot of paint on the brim which I attempted to clean up using a damp cloth.
I was able to get most of the paint off the spot, but now there's a faded paint stain, and to add to it, I believe it got a little soaked in water.
So now it has a water stain around the area.

I'd appreciate the help with this awful problem. I don't know what to do now.

I've used corn starch to remove water spots from light colored felts. A little goes a long way.
Gently rub in some corn starch, give it some time and brush the stain away.
Lots of brushing
