I've always had very good luck using either Formula 409 or Fantastic for tough grease. Spray, let it soak awhile, and then use a sponge to wipe clean. It's worth a shot!

White vinegar, then rinse it off with a clean, well wrung out dish cloth. I bet it will shine nice.

Use ammonia. Mix it with water, the directions are on the bottle. Ammonia is cheap and effective. Make sure there is plenty of fresh air when you open the bottle because ammonia has a very strong smell. Caution: Do not mix ammonia with bleach! Ammonia should be used by itself for cleaning and rinsed with water. Ammonia is safe if used as directed.
