Sharp electronic organizers with the IC card slot (Wizard OZ/IQ/PA/PI series)

Thanks to this thread, I now have a new toy to play with. My OZ-7000 arrived today.

One question I have is the outside case of your organizer fairly sticky? Mine was, and I tried to clean a small area with Isopropyl Alcohol and it didn't improve. Cleaning with fairly weak wet wipes seemed to make it better, but not considerably so. I've also used some leather cleaner wipes to put a little conditioner on the surface and that seems to help, but it still honestly feels a little tacky. Hopefully the IPA didn't damage the surface to the point of stickiness (it was tacky before starting).
