Handy tip for cleaning Amiga cases or any type of plastic as well as monitors keyboards, CD/DVDs, Washing machines, fridges, DVD players and lots of other things...
Use a UPVC cleaner (the kind for cleaning/restoring UPVC window frames/Patio doors) it brings things up like brand new without scratching and give them that feel that you've just taken them out the packaging...

Weird tip, I know, but it works...
