Light spots vs. heavy scale
| What you see | Usual meaning |
|---|---|
| Light spots on glass and chrome | Normal minerals drying |
| White flakes at hot-water taps | Sediment or scale in the water heater |
| Thick crust on one fixture | Old fixture or aerator |
| Heavy scale everywhere on a well | Hard well water |
Dark granite, black faucets and glass doors show spots most; light fixtures hide them. Two homes on identical water can look very different for that reason alone.
Why county water is usually soft here
Hollywood's report describes lime softening and membrane filtration for Biscayne Aquifer water and reverse osmosis for Floridan Aquifer water. The county's 2025 tables do not list a 3BC hardness figure, so testing at your tap is the quickest way to know your number.
If you see heavy scale only on hot-water fixtures, flushing the heater on its maker's schedule often helps more than any new equipment.
Cars and business vehicles
Washing vehicles with well water often leaves spots, and outdoor marks where sprinklers hit can come from the same source. Car washes commonly soften water to reduce spotting. If you run a business that washes vehicles, test the water source you use. See water softeners.
Ask any installer to show you the hardness reading before recommending a softener. If the number is low, the spots are about drying habits.
Softener or conditioner
Ion-exchange softeners remove hardness; salt-free conditioners do not. See salt-free conditioner vs. ion-exchange softener.
Everyday fixes
- Squeegee shower glass.
- Rinse aid in the dishwasher.
- Clean aerators and showerheads.
- Flush the water heater on the maker's schedule.
Cleaning what is already there
Diluted vinegar or a gentle descaler loosens mineral spots on glass and chrome; follow the fixture maker's instructions, especially on stone or specialty finishes. Water treatment prevents new buildup but does not remove what is already on surfaces.
