Hi all I have a Belkin Folio iPad case in suede for a month now and it seems that it's getting dirty like it stains my iPad screen when I keep it closed just wondering how you guys go about cleaning that up? It doesn't look too nice when I'm doing presentation to a client and when I open it up it's all greasy and yucky. Should I dipi the folio case in a washing machine? Is it ok to wet it in soap and clean it and rinse it in water?
