Not sure I would venture myself at tooth brushing the internal parts.

I would most likely do like Bruce and start with mild detergents/soap to see how that works then proceed, in safe areas, with some of the solvent based cleaners. Not an easy task .........

Any polish is going to have abrasives in it which will work at the original surface to some degree. Better dissolve and clean off the gunk without touching the surface you want to preserve if you can. Or polish off the original surface just enough to get a consistent colour and varnish the snot out of it.
