if you can manage to open the remote (and this is usually the most difficult part of cleaning),
you will find that the buttons are but a rubber pad with elevated nodules that correspond to the buttons. the underside of these nodules can be cleaned.
under the rubber pad are physical contact switches that can be cleaned.
done correctly, the remote is restored.
