I love my new iPhone 7 Plus! I've kept it clean and spotless since day one. However there is one problem! There is this gross buildup of white stuff in the earpiece and it looks awful! I have tried EVERYTHING I can think of to clean it. I've read every forum post and tried all their suggestions as well. NOTHING has worked and I really don't want to return the phone or try to get a replacement which will likely not work as Apple will say it's cosmetic damage and likely can't be replaced under warranty. I've tried spraying, wiping, brushing, vacuuming, q-tipping, tooth picking, blowing, YOU NAME IT! Nothing seems to get it clean again Please someone help me get my earpiece back to its original black glory!
