Side note on cleaning Apple products, may be of interest to iPhone users. My 2017 6S wasn't charging properly. Charge would start, then a few minutes later, sometimes less, it would stop. I found that many times, if I inserted the plug with a bit more force, it would start charging, but later, it would stop. As is common the cable was frayed near the plug, so I replaced the cable. The situation didn't change. I was at the point of deciding to replace the iPhone, since it was getting dated anyway, when my daughter suggested I clean the plug receptor.... the light bulb went on. I grabbed a toothpick and started pulling out lint. Like your bellybutton lint. There was a lot of lint. It had become packed into the base of the receptor sufficiently to prevent the plug from making the contacts. I had carried it in my pocket for 3 years, it likely gathered a few specks of lint each time I put it in there, and then I compacted the lint when I plugged it in next.
