Anyone know how I can clean this bad boy? I'm a welder so dust is imminent, but I don't want to bung up this phone right away. I cant take it apart due to the tork screws or whatever they are. And they don't make dust proof cases for these that I can find. Its mostly getting into the speakers since theyre magnetic. Any tips? Thanks all Edit I gently blow the speakers every few days with compressed air but I still imagine lots will get into the circuits etc.
