I clean remotes and other keypads with just a dry paper towel and a
little knuckle grease. Unless it was immersed in something sticky, this
is enough. Also, I've found the contacts, not the pads, are what need
cleaning; they oxidize. A paper towel is rough enough clean them. If
its really bad, use a pencil eraser followed with the paper towel.
Pencil erasers have some mind grid embedded in them. Electrical
engineers use an eraser to clean non-gold plated contacts, the eraser
will completely remove the gold and even copper plating.

Don't know, just guessing, but you might get bounces (multiple button hits).
