As for the plexiglass ... there's probably an entire site somewhere devoted to How To Clear Up Scratches or something like that. But I would think that some polishing compound -- like the kind tha is used to polish headlights -- might be useful. Or maybe toothpaste. It depends upon how much you care about the item.
It
is a nifty little novelty item.
