Cleaning contacts alone will not work.
Very easy fix. go to auto parts store and get permatex rear window defroster repair kit. Next remove battery cover and batteries and pry open remote. Once open take out the rubber sheet and clean the backside of connectors. Open the kit and find the small bottle of conductive paint and brush a small dab on all the contact let dry a few minute and reassemble. Just like that better than new. This fix can be done right at your customers house.
