Last year there was a thread about white stains on wine glasses and using vinegar to get them out. Well, I have now STUBBORN soy milk deposits on expensive wine glasses, thanks to a husband who likes to drink milk from wine glasses instead of the dishwasher safe glasses (and then leaves the dirty glass in the sink for me to wash, but that is another story). I cannot get them out with vinegar or soap and water. They look like cloudy white stains. Can anhone recommend any commercial products to try?
