How to remove dried polish/residue from hard to reach areas?

I'm dealing with a car that has some old dried wax or compound residue in and around the chrome window trim. This is actually a pretty common site. I was wondering what can I do to completely remove it?

Would the plastic razors do the trick that AG sells here or will that do more harm then good?

I tried everything to remove this stuff and it's in such remote and hard to reach areas that no matter what I do, it doesn't help.

APC with a soft bristle brush will do the trick. Pic of the spot?
