Hard Water Spots & Scale in Lauderdale-By-The-Sea

Indoor spots vs. outdoor film

• Inside: shower glass, faucets and dishes. Even softened water has some dissolved minerals that show when it dries.
• Outside: windows, railings and cars near the beach get salt spray, which is not a water-supply issue.
• Sprinkler marks: orange or white marks where heads hit can come from well water. See iron stains.

What your utility does

South of Pine Avenue, Fort Lauderdale softens at its Fiveash lime plant or treats with nanofiltration at Peele-Dixie. North of it, Pompano Beach membrane- and lime-softens. That is why a hardness test here usually reads low.

Pompano Beach's laboratory (954-545-7018) and Fort Lauderdale's Customer Service Center (954-828-8000) can answer questions about what their plants deliver.

Softener or conditioner

If a test does show meaningful hardness, for example on a well, an ion-exchange softener removes the minerals. Salt-free conditioners work differently and do not remove hardness. Read salt-free conditioner vs. ion-exchange softener.

Practical steps first

• Squeegee shower glass after use.
• Use a rinse aid in the dishwasher.
• Wipe dark faucets dry.

If spots persist after that, test before buying equipment.

When scale is a warning sign

• Thick crust in the water heater or kettle on softened city water can point to a fixture or heater issue rather than the supply.
• White deposits only on hot-water fixtures can come from minerals settling in the heater.
• Heavy scale on a well-fed home is common and usually does justify a softener.

Businesses with equipment

Restaurants and hotels in town run ice machines, dishwashers and boilers that can be sensitive to even modest hardness. Some manufacturers set their own water limits. Living Water installs ion-exchange softening plants for businesses where testing and equipment needs justify one. See water softeners.

Cleaning existing buildup

Mild acidic cleaners such as diluted vinegar loosen mineral spots on glass and fixtures; follow the fixture maker's care instructions, especially on natural stone and specialty finishes. Treating water only prevents new buildup. It does not remove what is already there.
