CKEDITOR, to auto Stip out all MS WORD when pasted

How can I get CKEDITOR to automatically remove all MS WORD formatting code when a user pastes in the editor?

I've noticed etherpad's editor handles this perfectly and it would be huge if CKEDITOR would. This is a HUGEEEE painpoint right now for my app and a reason I'll likely need to find another editor if I can't resolve.

Thanks
