I have had a bit of success with using a couple of strands of fine wire brush (still attached to brush (radio shack has a small solder brush in a soldering acc. kit that works well for this) placing the few strands through the plated through hold under the offending keys and slanting so it goes past the upper edge, overlapping into the contact area above. Rotate the brush strands while applying pressure to the key(s) to get contact cleaning wiping action. This process has returned to functionality key contact corrosion from battery packs which got into the keyboard for me, try at your own risk.
