What to do with this old War Horse?

[Gatorade]

This is my grandfathers Garand Bayonet. It had been stashed with some other stuff and was getting some rust on it. I need some suggestions on how to clean it up. Who knows, if it cleans up nice enough I may have to have Panther Concealment bend some Kydex for it and use it as my EDC! That would sure turn some heads! I took a bunch of pics so let me know what you all think I should do.
