The Apple Card isn’t just another credit card. Apple is a hardware company, after all, so its card is special, mkay? If Jony Ive hadn’t disappeared from the Apple lot, then we’d probably even have a Making Of video, with Whispering Joni1 burning with quiet passion about how this is the thinnest, strongest card that Apple has ever made. How Apple’s designers needed to invent an entire new production process to recycle titanium plates reclaimed from broken legs. Etc.
So, if you have an Apple Card, Apple wants you to treat it with respect. And that’s why there is now an official support document telling you how to clean it.
