There is also a product called Microscrub which is used in the electronics
industry. It is grey in colour and feels a bit like the soft half of
Velcro. Its purpose is to remove the dirt and corrosion from contacts
without destroying the protective plating.
Abrasives like sandpaper and wire brushes may clean the connectors well,
but if they also remove the protective surface of the contact, they may be
only a short-term solution. These connectors have taken 20 to 30 years to
deteriorate; for reliability, either clean them gently or replace them.
Keep the sandpaper for emergency repairs.
