Hello all! I just picked up a used M11x. I know that it's a bit old but I want to clean it up a bit. Any ideas for cleaning up a radio as far as sprays or specific brushes etc? Also, I'm finding that the radio is a bit creaky, any ideas on how I might be able to fix that? As I squeeze the controller it creaks. I know she's old but just throwing it out there lol.

Armor all it. For squeaks yeah mine does it also. Never tried to make it stop. All I care about is it's not beat up and it works.
