Many manufacturers, as one example, use ProGold wipes on card 
connectors on their production lines.

I use either ProGold or Deoxit on all connections, even simple stuff 
such as cells in a flashlight or remote control.

I use ProGold for plated connectors including my Schurr Profi II's contacts.

I use Deoxit for unplated brass or copper, or oxidized surfaces.

Both come in a wide variety of applicators, with a variety of 
concentrations and carriers.

My K3 kit will have ProGold on all connections.
