CLR or Lime Away? An acid-based cleaner is the best way to remove water deposits. Vinegar and lemon juice are two natural alternatives, but they just don't work as quickly and effectively. CLR uses similar ingredients to Lime Away.
First, scrub as much scum off as possible and then wipe it dry with a towel. After this is done, combine two parts baking soda with one part vinegar to make a paste. Using this, rub it onto all of the surfaces affected by the calcium buildup. Leave this on for about five minutes, letting it soften the mineral deposits.
