Clean up advice

[Stephanie]

Hey everyone

So I am trying to figure out the best way to start cleaning up some pieces, specifically the gauges and the steering wheel. I have several newbie questions for all of you, haha.
My questions are:
Would it be smart to remove the rubber covering the steering wheel since it is so cracked?
Will we be able to get that replaced later on?
Has anyone refaced their gauges themselves? I saw online how expensive they are to buy new ones and I am trying to see if we can just clean them up ourselves.
What is the best product to clean up the pieces and make them look new again? A friend mentioned covering them in ketchup... does that work?

Thank you all for your help and advice!
