Is the strip copper or some other material?

You can clean copper up with alcohol then brass polish and then more alcohol using a cotton washcloth as an applicator. Make sure to get every drop of the brass polish off and make sure the copper is completely clean. You may have to re-apply the brass polish once or twice depending on how badly the connector is tarnished. I've done this with card edge connectors in antique test gear, antique computers, and antique game cartridges.
The last step is to lube it with dielectric grease or, on PC board card edge connections like the VSS and Cruise III modules, Deoxit S5 Shield.
