I'm afraid the others are right and once you get these milky blurry marks on your glasses they are permanently ruined. If you've got good quality (espeically crystal) glasses, wash them by hand. We go for the easy option now except for the occasional posh dinner when we're entertaining and buy plain cheap glasses which can be thrown away once they become milky. I've tried everything in the past and nothing really worked.
