Unfortunately, = they were really yellow and didn't match their prospective neighbors in the = least.  There was discussion on the thread about sunlight = and peroxide and it seemed to be a pretty complicated procedure.  = Having nothing to lose but one old ivory... I filled a cup with some = laundry bleach and threw in one of the keys.  Twenty minutes later it was = a perfect white.  So, I threw in the other two and they also turned = white, but unfortunately I left them in too long and they warped into a = shallow U shape.  I put them side by side on the bench, laid my aluminum = ruler on top of them, and put my bowling ball on top of that.  (I had to = set a book next to the bowling ball to keep it from rolling off the bench.) End result: three perfectly matching white = ivories.  Whomsoever said that laundry bleach wouldn't work: not = true! Tom Sivak Chicago </BLOCKQUOTE></BODY></HTML>
