Calling all Damier Azur wallet owners

  1. I have a Damier Azur Koala wallet. I have been using it since July. I noticed the edges around the wallet are getting dirty (i can see grey color on the edges). Does anyone know how to clean it? I used the coach leather cleaner but it doesn't work. I don't want my wallet to get dirty. Help please. TIA

    By the way, I got a new job about 1.5 months ago and since then I don't have time to come to TPF that often (whereas at my old job i was on TPF everyday!). Just want to tell you all I miss everyone/everything here! ;)
