Over spray

I have a lot of over spray in the door shuts, inside of the boot ect were my car has had a colour change outside but not the inside to match. What's the best way to remove blue 2 pack over spray from white paint work?

Also have blue finger marks on my white roof lining? Any suggestions.
Would have preferred the previous owner to leave it white!

Thanks Grant

Rubbing compound.

1500/2000 grit wet n dry?

You could prob get away with some polish.Im guessing the door checks havent been prepped for paint so the overspray wont be that hard to get off,polish and elbow grease!
