Apple warns against storing its titanium credit card in leather

The titanium Apple Card looks slick (with the sound to match), but you may need to treat it gingerly if you expect it to look as pristine as the day you got it. Apple has posted a cleaning guide for the physical credit card that warns against storing it against leather and denim, lest they cause discoloration that "will not wash off." Yes, that's right -- you could end up with a nasty-looking card simply by putting it in your usual wallet or pants pocket. Many leather wallets have linings, and plastic cards have their own issues, but this suggests it's more delicate than some would like.
