Does anyone know what I can use to clean Split Jaw Clamps, I have over 50 that's turn almost black. Tarnx didn't help.

  Acid will not clean brass the way you want it to. Your split-jaw clamps have weathered to a darkened patina. If you are concerned about electrical continuity, all you have to do is take a piece of very fine wet-sanding paper and run it over the inside of the groove where the railclamps make connection with the track. It doesn't require that it be shiny clean for good conductivity! There's no way to keep brass from darkening outside unless you paint the brass with clear polyurethane paint and that would ruin your conductivity.

I have used "Brassso" to clean used track almost back to it's original shinniness. Should work that way on rail clamps.
