I have a pretty expensive mouse pad, it's a SteelSeries surface QCK+. It's made of some cloth on the top and has a rubber base and it's 450x450mm in size. Over time (I have it for about a year) it became dusty and a bit greasy.
How should I clean it? Can I just wash it as I do with some clothes? Of course, not in a washing-machine, but in warm water with some cleaning stuff like AJAX
I understand that this question is a bit off-topic to SuperUser, but who can know it better? :)
