My place was built in 74, so I've got aluminum wiring upstairs. What we did is we pulled every wall plug and switch out, put a 6" copper lead on it so we could use the SIGNIFICANTLY cheaper Cu-hardware (Al rated switches and outlets are goddamn expensive), we used anti-corrosion compound on the Al-Cu connection, and then wrapped the outlet with electrical tape.
That last step is 'unnecessary' when using Cu wire, but as Mac said, the Al connections come loose, sometimes fall off the outlet, and start house fires =/
So that's why you always double secure your connections! Wrap the outlets so even when the Al wire comes loose at the connection, it can't fall off the outlet.
