Unless someone has painted the parts, most are molded color-through. This would be the case for the tan, grey, and charcoal parts.
The silver parts are painted, and some of the black buttons are (the hazard button is actually red, with a coat of black, and then a thin coat of silver on the silver-trim trucks).
303, Armorall, and other protectants won't soften or remove paint. You have to be careful with other cleaners such as Simple Green (generally pretty gentle)... 409 WILL tear up the silver, and I've had "Fantastik" permanently spot a windshield on my '69 Buick.
For 90% of interior grime, all you need is something wet with a mild surfactant to break the surface tension of the water. Most of what we encounter is simply dust, and the occasional sneeze or cough "residue"... and those clean up just fine with a damp cloth.
The areas that will need a bit more, such as the door panels, arm rests, sill plates, and kick panels, are molded through and are going to be impervious to anything that won't melt the plastic. Simple Green, or Dawn are good, safe detergents.
