Fifth Element, The - The Amazing Self-Washing Stones
After Corbon Dallas (Bruce Willis) runs over to the blue alien diva who got shot, he takes the stones out of her and they're covered and probably stained in blue blood. When they go to the place where they align all the stones they're magically washed and are their normal color. And I didn't see them stop by any laundry mat along the way, they went straight to Earth in that little alien ship.
The movie, DUH!
