It doesn't matter if you have a dishwasher or do things by hand; there are some pieces of glassware that lose their luster after awhile. It might be water spots, they might be slightly dingy. Either way, they could use some freshening up. Want to know a little trick?
A simple dish rag or towel with a few tablespoons of white vinegar on it is all you need to clean things up. It will evaporate and leave you without any taste, but if you're still worried you can fill a shallow pan or plastic dish tub with hot water and add 2 cups of vinegar to it. Give things a soak, shake off excess water and let sit to dry.
If you have a dishwasher, you can add straight vinegar to the rinse aid compartment for an added boost, but some cities have hard enough water it might not be enough, but it's worth a shot! Your spots will be gone and you can breathe easily when your mother in law comes for dinner, or your guests are checking out your open shelving kitchen!
