For lack of knowing how the interior panels are plated or clear coated, I would recommend going easy on the abrasives when scrubbing down, so you don't damage them. If the plating / coating is thin, you could scrape right through it and end up creating a serious corrosion issue down the road.

An old cotton t-shirt and a mixture of bleach and water should be sufficient to clean it and shouldn't risk damaging the coatings/plating. For stubborn spots, a nylon bristle brush like those used to clean pots and pans should be sufficient. I would avoid abrasive cleaners like Ajax, comet, etc. and things like scotchbrite pads.

I was just going to sand it down to metal and do a primer and base coat before doing some designs on it. The exterior does have a couple scratches that are down to the metal already. I don't think I'll do anything with the interior. No scratches or anything there.
