DYEING A TUFF WHEEL

It looks pretty close to the dash pad.

Have you tried cleaning it real good?

How is the finish?

The can vary from slick, to porous foam.
I guess the stuff doesn't look too bad for 50 years old. I tried cleaning the dash, but the dark black didn't come back. What would you recommend for a good cleaning product for both? Maybe I shouldn't have powder coated the dash frame.

The wheel sure doesn't feel like foam.
