Balm On Chin Fur

One of my chins is very squirmy and doesn't like to be held, but I have to hold him when applying balm on his dry ears which causes some.. slippage when it comes to putting the balm on his ear from my fingertip. So now there's a pretty visible amount of balm residue around his ears on his head and even on his forehead. (No idea how that happened. ) It makes that area look like he's never had a dust bath! Any help on how to remove it is greatly appreciated.
