Ever wonder why your glasses become cloudy over time? That’s because you are using too much detergent when you wash them. The dishwasher’s rinse cycle doesn’t have time to get rid of all the suds, so what you are seeing on the glasses is soap scum. You can nix the buildup by putting a cup of distilled white vinegar into the bottom of your empty dishwasher and running a cycle. The acetic acid in vinegar will easily dissolve soap scum to give you a fresh start.
