I had this same problem with the steering wheel on my 37 truck. I washed it off with lots of soap and water, soaked it and washed it even more until I was down to the real wheel material. A nice paint job after that and it has been beautiful ever since. You are looking at a steering wheel that is 70 years old - allot of hands, usually dirty hands, with a truck, have been on that wheel!
