Does anyone know what type of material the cloth of the stock ceiling is for the tC? I don't think it's suede because it feels different from shoes and other things I know have suede. If you know the material, what do I sue to clean it? It's filled with dirt and I need to clean it off. Any help is appreciated. Thanks!

 

I'd try cleaning it with some upolstery cleaner made for seats and carpet and follow the instructions.

 

Eagle one has something like a nano protectant for carpet/upholstery. After my spring install there was black hand marks all over the tan suede-like material in the back hatch and they came out easily with the product. Took out all the bad odors and the material feels smoother too.
