I know this is a rather stupid and "first world problem" crap but...how do you deal with the dust that gathers on the edges of the iphone 6 and 6s while using the leather ore silicone apple case? I bought a 6s and with a a few apple cases. Clearly, the silicone one is the worst but what about the leather one? When I take my phone out of the pocket, there is a lot of dust on the edges and it looks awful, especially on the black one. I cleaned my pocket and it looks spotless but after a few days, dust comes back so this is not a good option to clean it everyday.
