I have a Logitech keyboard and an i-Ball mouce. Now it so happens that someone who had some sticky grease/oil level stuff on their hands did not wash them properly and used my keyboard and mouse. Sad thing, but its not that prominent and its not all that serious. It is just plain irritating. The only problem is that when I use the two, i get the same stickyness in my hands which does not go away till a good hand wash has been used. What can I do to get it off the keys/mouse?
