Water stains

  1. So I'm not totally clear on how water stains happen (am posting this b/c the other rain thread made me think of this)

    So sometimes when I get water on my handles, it dissapears. Other times, I get a faint water stain. What gives? How come some water is OK and others are harmful?
     
  2. Come on, people!! No responses yet!! Where are all the experts?
