"Some fabrics, like leather and denim, might cause permanent discoloration that will not wash off," Apple warns card owners.
[...] The BBC rounded up a number of Tweets from early adopters confirming that the physical card might look nice when you get it, but probably not for long after. "I can say from two months of having the card in my leather wallet, it no longer looks pretty," one owner wrote.
The damage is cosmetic only; the card will still work at a point of sale if you dare to keep it in your wallet. If you would like to keep it looking new, however, Apple recommends wiping it gently with isopropyl (rubbing) alcohol using a soft microfiber cloth.

Maybe they are / materials engineering working triple-overtime to come up with some coating or different alloy. (Hey, it's a credit card of a different material and preparation! Why bother testing it?) And when they get a replacement they'll try and substitute them as quietly as possible.
But you know class-action suit is coming in 5... 4... 3...
Although I'd lean towards fine, what really makes me wonder is that if they didn't test it for staining, did they do anything to test it biologically for harm in skin contact? Welcome to the last card you'll ever own! Although Titanium is biogenically compatible, so maybe that's not an issue.
