Various automotive vinyl cleaners have some "plastic restorers". Classic is NuVinyl brand in the original white container; there's new mixes now. Some of these auto products also add a shiny coat, that can be scuffed off. All these contain "plastisizers" to replace those dissipated by age. The chemistry of rubber products can be interesting. - regards, Herb -- Herbert R.
