Review on Set of 6 Short Whiskey Glasses - 11 Ounce Rocks Style, Ideal for Camping and Party by Hayden Hart

I'm a little surprised by the reviews that mention dishwashers. I've been wearing the glasses for a little over 2 years and they have cloudy/white streaks that I can't get rid of even with vinegar. I have a good dishwasher and only use Cascade Platinum with rinse aid, I wash my dishwasher regularly and my water is not "hard". So after some research I have to say it's probably soft water corrosion and therefore the glasses probably aren't dishwasher safe, despite what it says (although it's not obvious at the bottom of the page, not in the main description). Why? I do not know. Apart from that, despite frequent use, NONE of them have broken and they are very good looking glasses. I just want them to stay as clean as the day they arrived.
