I have been carrying my Neverfull for about a month now, and its starting to get a great patina - slightly darker than new, and a beautiful shade. I've gotten a few spots on the vachetta that I used baby wipes on, and I ordered a protective spray. So now, I love the color, but am wondering if there's anything I can do to prevent it from getting a lot darker...magic eraser? Regular use of baby wipes? I don't mind a nice patina, I'm just afraid of dark dark. Epecially since my Azur Speedy is arriving this week, and I am worried about it too!! Do you do any regular maintenance? Thanks!
