Now that the Apple Card is available, Apple added a page to its support website explaining how to keep it clean. But the page also reveals something surprising: keeping your card in a leather wallet or jeans pocket is a really bad idea.

The Apple Card has a white finish with the credit card holder's name and the Apple logo laser-etched into it. The white color is achieved "through a multi-layer coating process that's added to the titanium base material." I doubt many people until now have thought about how to keep their cards clean, but as with most things from Apple, it's a designer object as much as a functional one and needs to be looked after.

Keeping the Apple Card clean is pretty simple. Wipe it with a lint-free microfiber cloth; for a more thorough clean, moisten that cloth with isopropyl alcohol. Maintaining the white color of the card is more difficult, though, because of how it reacts to different materials.

Leather wallets are quite common, as are the wearing of jeans. However, Apple warns that putting your Apple Card in contact with leather or denim "might cause permanent discoloration that will not wash off." So if you want to keep your new Apple Card looking new, it's time to trade in that leather wallet or purse and stop sliding it into your jeans pocket. Doing either is probably going to damage it.

I'm going to say it if no one else will, but launching a credit card that you can't keep in a leather wallet or jeans pocket is ridiculous. Apple made the card look a certain way, but clearly never took the time to consider the materials with which it would most commonly come into contact. Leather in particular was always going to be high on that list.

Apple's advice for storing the card is to use a wallet, pocket, or bag "made of soft materials." Don't store it alongside other cards, keys, or loose change to avoid scratching, and magnets should be avoided. Those are all common sense, but Apple should really be making it very clear you can't use a leather wallet. Instead, we're now likely to get an influx of "Apple Card Compatible" wallets coming to market.
