I was just cleaning up some rims and spokes from '81. The rims cleaned up really well, but the spokes took some more work. I sprayed them down with WD 40 then used 600 grit sandpaper. After that, I used stainless steal cleaner (only polish I had handy) and they turned out really nice. If you have some time to kill and you like to tinker, they can turn out nice.
