Now the wine glass is all foggy. Is my glass doomed or can this be undone? post:ask.metafilter.com,2007:site.59271 Fri, 23 Mar 2007 11:34:24 -0800 umlaut wine glass http://ask.metafilter.com/59271/Foggy-Wine-Glass#891263 Plain glass? Can't you just wash it, possible with something that removes mineral deposits? comment:ask.metafilter.com,2007:site.59271-891263 Fri, 23 Mar 2007 11:46:52 -0800 DU http://ask.metafilter.com/59271/Foggy-Wine-Glass#891267 It's probably just minerals once dissolved in the water, that are clouding the glass, but it could be some algae growth, too. A couple ounces of vinegar (which is dilute acetic acid) swished around in it will probably dissolve them completely. Heat the vinegar a bit in a microwave before putting it in the glass, for faster action. comment:ask.metafilter.com,2007:site.59271-891267 Fri, 23 Mar 2007 11:48:33 -0800 paulsc http://ask.metafilter.com/59271/Foggy-Wine-Glass#891271 It's the Riedel "O" series. It was a gift; not sure if it's crystal or not. Looks like the fog you get after years of dishwasher washing. (Which I wouldn't do to a wine glass.) comment:ask.metafilter.com,2007:site.59271-891271 Fri, 23 Mar 2007 11:49:58 -0800 umlaut http://ask.metafilter.com/59271/Foggy-Wine-Glass#891305 Let some white vinegar sit in it for an hour. comment:ask.metafilter.com,2007:site.59271-891305 Fri, 23 Mar 2007 12:23:38 -0800 Steven C. Den Beste http://ask.metafilter.com/59271/Foggy-Wine-Glass#891334 Vinegar should work. I use it to remove water marks inside glass vases. Efferdent (fizzy denture cleaner) also works. comment:ask.metafilter.com,2007:site.59271-891334 Fri, 23 Mar 2007 13:06:15 -0800 wryly http://ask.metafilter.com/59271/Foggy-Wine-Glass#891368 toothpaste. comment:ask.metafilter.com,2007:site.59271-891368 Fri, 23 Mar 2007 13:33:39 -0800 Hugh Jorgan http://ask.metafilter.com/59271/Foggy-Wine-Glass#891419 2nd toothpaste. comment:ask.metafilter.com,2007:site.59271-891419 Fri, 23 Mar 2007 14:36:34 -0800 matty http://ask.metafilter.com/59271/Foggy-Wine-Glass#891447 Most toothpaste contains powdered silica, which can permanently fog glass if you rub it. Don' t try using toothpaste unless other approaches fail, and only use it after trying that toothpaste on some other glass that you don't care about. comment:ask.metafilter.com,2007:site.59271-891447 Fri, 23 Mar 2007 15:32:09 -0800 Steven C.

If you are in the mood to experiment I would try it. comment:ask.metafilter.com,2007:site.59271-891560 Fri, 23 Mar 2007 17:46:31 -0800 Brian B. http://ask.metafilter.com/59271/Foggy-Wine-Glass#891587 I learned recently the power of vinegar to clean stainless steel pans; I'd surely give it a try, the stuff is amazing as a cleaner. comment:ask.metafilter.com,2007:site.59271-891587 Fri, 23 Mar 2007 18:30:20 -0800 dancestoblue http://ask.metafilter.com/59271/Foggy-Wine-Glass#892827 It can be undone. You should specify if the glass is glass or crystal. comment:ask.metafilter.com,2007:site.59271-892827 Mon, 26 Mar 2007 11:57:35 -0800 Four Flavors
