Q: I have a small set of Candlewick glass, but three of them are cloudy. I believe this is from being washed in a dishwasher. Is there any way to make them clear again?
A: Cloudiness is caused by deposits of calcium carbonate left by new phosphate-free dishwasher detergents, especially if they’re used with hard water. Manufacturers removed phosphate from their dishwashing products in 2010, after several states banned the ingredient because it contributes to the growth of algae in the environment. To clear up cloudy glasses, put a cup of white vinegar on the top rack of the dishwasher and run the glasses through the cleaning cycle without detergent. To prevent it from recurring, clean your dishwasher every six months and use less detergent when you run the dishwasher. You can also add a little citric acid to the detergent.
