Thanks all for the answers. I tried vinegar on q-tips but that doesn't
seem to get rid
of the blue-green...some came off but there's still plenty left. I'll try
water and
baking soda next but I'm a bit worried about water seeping into the
electronics...any
ideas for preventing that (I could hold the scanner upside down but that
might be
awkward.

Don't use baking soda, it's not acid, it's a base.
