I brought my Chumby into work to show it off to some folks.   When I took it out of the pouch I realized I needed to clean my 3'yr old's smudges and marks from the screen and surrounding latte casing.   I had a lint free glass cleaner rag (for my glasses) and sprayed just a hint of cleaner on it to wipe away some of the grim and wouldn't you know it the RED rag has now discolored the outside casing. Do'h!! Before I initiate a downward spiral of ruining the casing altogether: can a replacement casing be purchased (be cool to have multiple colors anyhow)? And, what do folks use to clean yours?  I thought about dabbing a lil bit of bleach water to see if I can restore its luster.  thoughts/comments...
