How do I remove hard water deposits from stemware?
By andyandotcanup from Independence, MO
Put a few inches of water in a large bowl or kitchen sink. Add a few inches of distilled vinegar. Soak glasses for 10 minutes, remove, rinse immediately, then dry. If spots are not gone, you will know right away. In this case, place them back in water/vinegar a bit longer and repeat the ending steps, drying completely. This should help. (08/23/2009)
I would use straight vinegar, or even CLR. CLR and vinegar do not hurt glass. I am not sure about lead crystal, so if these are very expensive crystal stemware, you might try googling for some cleaning info about that. However, I suspect if it is not, then vinegar or CLR will do the trick.
If this is a deposit that forms when they are in the dishwasher, you can pour a cup or so of vinegar in the last rinse load, and that should help prevent the problem. I had to do that in one house we lived in that had very hard water. (08/23/2009)
Ahh, the hard water in Missouri! Well, I use distilled vinegar in the rinse-aid dispenser in the dishwasher and this prevents those stains. Try mixing a bit of baking soda and distilled vinegar to remove those spots. (08/29/2009)

Try a paper towel and white vinegar. The vinegar smell will dissipate as it dries.
Easier still; fill the glass to above the mark with plain vinegar, let stand overnight. If the mark hasn't dissolved fully, give it another day. I bought a gorgeous crystal vase at a thrift store for about 4 dollars that had a similar stain, overnight and the mark was gone! (11/01/2005)
Even easier, just fill the sink with water, pour in a glug of vinegar (maybe a quart or less?), put in the glassware and let it soak a bit. Then just wipe the scum off. We have incredibly hard water and I clean the film off our glasses every few months (well, maybe more often if company is coming and I want to impress them). (11/01/2005)
First, I found that the dishwasher leaves a lot of hard water spots so I now wash all my glassware by hand.
When I do find hard water spots, I use Lime-Away in a spray bottle. A very small amount sprayed on the spot usually does a pretty good job. (11/02/2005)
Fill the stemmed piece with vinegar diluted with a little water and let stand about 20 minutes. Wash and dry. (11/02/2005)
I have hard water as well, when my dishwasher is on the rinse cycle I pour a little vinegar in it and I have no hard water spots. A lot easier than washing by hand! (11/04/2005)
