I used a lot of paper towels and Dawn to clean and lots and lots of kerosene. I applied the kerosene with a brush. I kept going over and over it.
very dirty - it seems like someone must have sprayed something in there - it was coated but good. Nooks and crannies collected full of it. I losened the part that holds the shuttle in place but decided not to remove the shuttle. Since I loosened it I could clean pretty well. I turned it every direction - took a lot of time since it was VERY gunky.
