Speaking of erasers, I've been told that one should always use a white draftsman's/artist's eraser for this purpose. Never a common pink pencil eraser, and never a highly abrasive ink eraser. The white erasers are available anywhere art and drafting supplies are sold (including office supply stores), but I use an old electric drafting eraser that makes quick work of dirty contacts. But just be extra careful to avoid mechanically damaging any poorly-adhering pads if you use a powered eraser!

If you've never heard of an electric eraser before, here's a random picture from the internet of the same model that I have:

It holds a long eraser stick in a chuck and spins it like a low-speed Dremel tool. But you don't need the electric eraser to get the job done; just the right kind of white eraser, in either stick or block form, and a bit of elbow grease.
