Undoing greasy detailing mess

[andbaron]

My 1998 323is is in generally pristine condition, but I recently took it for a wash and had an incident. The guys at the carwash cleaned the inside (ALL surfaces) with some oily, greasy garbage, and every surface now has a nasty shiny residue on it.

What's the quickest, easiest and safest way to remove it? I am very much a novice here and have read mentions of woolite, meguiars all purpose, 303... I have no idea how to judge any of the above. Any help?

Thanks

Drop of dish soap in a bucket of water and a wash cloth, just slightly damp. Use a second dry wash cloth for any excess water.

OP where are you? Did you try any of the suggestions above? If so, did any of them work?
