Removing Salt Film and Algae From a Naples Pool Cage and Lanai

Ask any Naples homeowner what part of their property gets dirty fastest and most will point to the pool cage. Screen enclosures and lanais sit in constant humidity, catch salt spray, and stay shaded and damp, which is a perfect recipe for algae, mildew, and a dull salt film on the aluminum frame. Left alone, the growth turns the screens black, makes the pool deck slippery, and can shorten the life of the enclosure.

Why the pool cage is the worst offender

A screen enclosure traps moisture. Rain and pool splash keep it damp, the fine mesh holds pollen and salt, and the shaded frame never fully dries out. Add Southwest Florida heat and you get rapid mildew growth on the screens and a chalky salt film on every aluminum bar. On waterfront homes in Old Naples or on Marco Island, the salt component is even heavier because sea spray reaches the cage directly.

Why you should not just blast it

It is tempting to point a pressure washer at a dirty screen, but high pressure tears the mesh and blows out the paver sand in the deck below. Screen replacement is expensive, and re-sanding pavers is a job in itself. The correct approach is a low-pressure soft-wash: a mild cleaning solution is applied to the screens, frame, and deck to dissolve the algae, mildew, and salt film, then everything is rinsed gently. Nothing gets torn, and the growth is killed at the root rather than just knocked loose.

What a proper cage cleaning covers

• The screen panels, top to bottom, to clear mildew and restore visibility.
• The aluminum frame and kickplates, to remove salt film and oxidation.
• The pool deck itself, whether it is pavers, concrete, or a cool-deck coating, so the whole area is clean and less slippery.

How often it needs doing

Because of how fast enclosures grow mildew, most Naples pool cages benefit from a soft-wash every 6 to 9 months. Homes right on the water may want it sooner to stay ahead of salt. Keeping it on a schedule is far cheaper and easier than letting years of buildup set in, which can stain the frame permanently.

A clean cage and deck completely change how a backyard feels, especially before season when guests arrive. See our pool deck and lanai cleaning, or get a quote for any exterior surface in Naples.
