One SadTerminal Block

How is the best way I can clean up the fuse terminal block. Mine is not so much corroded but a little rusty. This causes one or more parts of my electrical system to go out at any time. There is nothing wrong with the wiring and everything workes after wiggling wires and holding my breath. But it's hard to do that driving down the road.
Thanks
