Does someone now how to effectively clean up the headphone & lighting ports along with the speaker & microphone to remove all debris/dirt that gets stuck in there? I haven't been able to come up with a solution that would do so effectively to make it look good as new. Have tried using compressed Air as one does for cleaning the fan and internals of a MacBook but haven't seen any difference that it would make. Spoke to Apple support and recommended a cue tip but I don't know that I know of any that small that could get in the microphone and speaker openings not to mention that I just might add more debris in there. Any suggestions that won't damage the phone?
