A little trick i've picked up is to use Woolite for cleaning interiors. Its my wonder/allpurpose cleaner. Used in a 6:1 ratio in water its pretty tough on dirt and safe as well for carpets and dashes. Be careful w/ the headliner as to not rough it up too much, be gentle w/ whatever you use.
I clean everything, even my leather w/ the Woolite mix, and i really like 303 Aerospace Protectant on my dash. Its good stuff and not too shiney.
