Mike I am not an expert .But I just use a damp cloth and am careful not to get water under the fininsh .Usual I take my time and do a little every day over a few days .A soft paint brush works good on cracks will dirt in them . Watch out for your dial glass . Depending on the model of your radio you can wipe the print right off. Not sure about gojo. But I have had good luck with water ,just takes time to soften grime up.Try the go jo on a small spot and see how it goes. After cleaning I have used Hardens furniture polish with good results . It is loaded with mineral spirits and does not get any harsher than that .Still it did not hurt the fininsh on my console. So if the gojo works good post the results back here and I will try it. Good luck !
