Why does my water leave spots on my glasses, coffeepot and showerhead?
When water is heated, cooled, or evaporated, minerals in the water may leave harmless white spots on glasses, coffeepots, and showerheads. Vinegar can be effective in removing these spots - soak showerheads in a bowl of vinegar and fill coffeepots with vinegar and soak overnight. Be sure to rinse well before using. There are also store products that can be purchased for preventing spots on glasses.
