"Purple" degreaser which can be found at 'Depot, Lowes's, Sam's or
similar works very well. I prefer Zep brand, but they're all pretty
similar. Wear gloves and chem splash goggles when using lest you
dissolve your hands or eyes. Rinse well when done. They have a wide
dilution range so start out weak and add more degreaser until you are
happy with how fast it works.
