If your pool cage or lanai screen enclosure has started showing orange-brown streaks along the frame or screws, you’re not alone — it’s one of the most common exterior issues Florida homeowners deal with, and one of the easiest to make worse with the wrong cleaning approach.
Why Florida Pool Cages Rust So Fast
Florida’s humidity is the main culprit — constant moisture in the air accelerates oxidation on aluminum frames, fasteners, and screws far faster than in drier climates. Sprinkler overspray adds mineral deposits that combine with that moisture, and coastal or lake-adjacent properties see it happen even quicker due to salt content in the air.
Why Pressure Washing Alone Can Damage Screens
Standard pressure washing equipment is far too aggressive for screen enclosures — the mesh can tear, stretch, or blow out entirely under direct pressure. Even the aluminum frame, while more durable, can pit or discolor if the wrong pressure and technique are used.
The Safe Way to Remove Rust from Aluminum Frames & Screens
A low-pressure, chemical-assisted soft wash approach is the standard for pool cages — it lifts rust and mineral staining from the frame and screens without the force that damages mesh. This is the same principle behind soft washing a roof or siding: enough cleaning power to remove the buildup, without enough force to harm the surface underneath.
Preventing Rust Stains Going Forward
Redirecting sprinkler heads away from the cage frame helps significantly, since repeated overspray is one of the biggest contributors. Regular gentle cleaning (rather than waiting until rust is heavily set in) also keeps stains from building to the point where they’re difficult to fully remove.
FAQ
What causes rust stains on a pool cage or lanai?
Humidity, sprinkler overspray, and mineral-heavy water combine to accelerate oxidation on aluminum frames and screws.
Is it safe to pressure wash pool cage screens?
No — standard pressure washing can tear or stretch screen mesh. A low-pressure soft wash approach is the safer, more effective method.
How often should a lanai be professionally cleaned?
Most Florida lanais benefit from cleaning once or twice a year, depending on sprinkler exposure and how close the property is to the coast.
