How to Clean a Pool Cage and Lanai Screen in Central Florida

If you own a home with a pool cage or screened lanai anywhere in Polk County, you already know the screens don't stay clean for long. Living this close to water and in Florida's year-round humidity, the fine mesh and aluminum frames collect a green or black film within a season or two. Homes backing up to Lake Hollingsworth, Lake Parker, or any of Lakeland's 30-plus lakes tend to see it fastest, because still water and shade are exactly what algae and mildew like.

Why screens grow algae and mildew so quickly

A screen enclosure is basically a giant air filter. Pollen, dust, lovebug residue in spring and late summer, and airborne mildew spores all settle into the mesh, and our humidity keeps that surface damp enough for growth almost every day. The aluminum frame develops the same black streaking you see on gutters. None of this is a sign you did anything wrong; it's just what happens to screens in Central Florida.

Why you should never pressure-wash a screen enclosure

This is the single most important thing to understand: screen mesh and their spline are not built to take pressure. A pressure washer will stretch the mesh, blow panels loose from the frame, or tear them outright, and re-screening a full cage is expensive. High pressure also strips the protective finish off the aluminum, which invites corrosion in our salt-and-humidity air.

The safe method is a soft wash: low pressure, roughly what a garden hose puts out, paired with a cleaning solution that actually kills the algae and mildew rather than just rinsing the surface. That's the same approach used for roof cleaning and any other delicate surface.

A safe do-it-yourself approach

• Wet down nearby plants and pavers first so no cleaning solution sits on them.
• Use a pump sprayer with a mild, screen-safe cleaner. Never a gas-powered pressure washer.
• Work in shaded sections or early morning so the solution doesn't flash-dry in the sun.
• Rinse gently with a hose from top to bottom.
• Check the spline and corner brackets while you're in there; humidity loosens them over time.

Well-water homes on the outskirts of Lakeland have an extra problem: iron in the water can leave rust staining on the frame and screen, which needs a specific treatment rather than plain soap.

If your cage has years of buildup, a two-story pool enclosure, or rust that won't budge, that's where a pro soft-wash makes sense. See our pool deck and lanai cleaning service for the full scope.
