I, too, live in FL and calcium/lime scale deposits get on glasses and
shower doors etc. If you can possibly manage, buy a water softener to
treat the water. If not, you might try getting some rinse aid
especially for the dishwasher. White vinegar added to rinse water
helps a little when washing clothes. My water softener broke three
weeks ago and we are trying to fix it ourselves, ordering parts, etc.
The glasses have already started looking cloudy.
