Screen enclosures and pool cages are among the most distinctly South Florida home features — and among the most commonly neglected when it comes to exterior cleaning. Most Fort Lauderdale homeowners pressure wash their driveway and pool deck periodically, but the screen enclosure gets treated like an afterthought until the green streaks are so visible they can't be ignored from inside the house.
The good news: screen enclosures clean up dramatically well. The hesitation most homeowners have — "won't pressure washing tear the screens?" — is legitimate, but it's based on a misunderstanding of what the correct cleaning method actually is. Soft washing is the answer, and when done properly, it restores screen enclosures without risk of screen damage.
What Makes Screen Enclosures Dirty in Fort Lauderdale
Fort Lauderdale's combination of humidity, salt air, and year-round warmth makes screen enclosures a prime target for biological growth. The specific contamination profile:
- Aluminum frame oxidation and mildew. The aluminum extrusions that form the frame structure develop a gray-brown oxidation layer over time, compounded by mildew growing in the moisture that condenses on the metal. On white frames, this looks like a dirty gray film that can't be rinsed off.
- Green algae on screens. Screen mesh creates a perfect surface for algae colonization — the weave structure provides attachment points and retains moisture after rain. In shaded enclosures, green algae can make screens appear opaque and dark.
- Salt air deposits on glass and frames. For homes near the Intracoastal or Atlantic coast — Harbor Beach, Las Olas Isles, Nurmi Isles — airborne salt deposits create a white mineral film on both the screens and the frame, reducing clarity and accelerating corrosion of the aluminum.
- Organic debris accumulation. Leaves, seed pods, and organic material blown against the screens by wind become lodged in the mesh and frame intersections, holding moisture and providing nutrients for fungal and algae growth.
Why Pressure Washing Screen Enclosures Is a Bad Idea
Screen mesh — whether standard fiberglass, pet-resistant, solar screen, or no-see-um mesh — is not designed to withstand direct high-pressure water impact. The risks:
- Screen damage and tearing. PSI above 1,000-1,200 directed at screen mesh can stretch, distort, or tear the material. Pet-resistant and heavy-duty screen types handle more force, but standard fiberglass screen is quite vulnerable.
- Frame joint compromise. The spline that holds screen material in the frame channel can be dislodged by high-pressure water, causing screen sections to come loose or pull away from the frame.
- Water intrusion. High-pressure water blasted at an enclosure can force water past screen seams and into the structure, potentially reaching the pool deck, outdoor furniture, or interior areas.
- Aluminum finish damage. Many Fort Lauderdale screen enclosures have anodized or painted aluminum frames. High-pressure water strips these finishes unevenly, leaving the frame looking patchy and accelerating oxidation of the bare metal.
The Correct Method: Soft Washing at Appropriate Concentrations
Professional soft washing for screen enclosures uses a lower sodium hypochlorite concentration than we'd use on a stucco wall or concrete tile roof. Screen mesh and aluminum frames require gentler chemistry:
Chemical Selection
We use a diluted sodium hypochlorite solution — typically 1-3% active concentration for screen surfaces versus the higher concentrations appropriate for masonry — combined with a surfactant that helps the solution wet the hydrophobic screen mesh fibers evenly. The surfactant also acts as a penetrant that gets the cleaning chemistry into the weave of the mesh rather than just coating the surface.
For aluminum frames, we select chemistry that is pH-neutral to mildly alkaline — avoiding highly alkaline cleaners that can cause aluminum oxidation, and strictly avoiding acid-based cleaners that will etch aluminum and glass.
Application Method
The soft wash solution is applied using a low-pressure soft wash system — essentially a chemical-injected garden hose pressure application that wets the entire surface without mechanical impact. Both sides of the screens are treated: the exterior face (which accumulates the most biological growth) and the interior face (which accumulates dust, mildew, and indoor air contamination).
After application, the chemical solution dwells on the screen surface for 5-15 minutes, depending on the contamination level. During this time, the sodium hypochlorite oxidizes and kills the algae, mold, and mildew. The surfactant holds the solution in contact with the surface rather than allowing it to run off immediately.
Rinse Phase
Rinsing is done with a low-pressure stream — not a pressure washer — from the top of the enclosure down. This removes the dead biological material without mechanical stress on the screen mesh or frame joints. We work section by section to ensure complete removal of the cleaning chemistry, which is important both for thorough cleaning and to prevent any residual chemical from affecting pool water chemistry if the rinsate reaches the pool.
Pool Water Protection
This is the question most Fort Lauderdale homeowners ask when we discuss pool cage soft washing: "What happens to the pool water?"
A small amount of rinse water containing diluted cleaning solution will inevitably reach the pool water during an enclosure cleaning. In the volumes involved in a typical service — and at the dilution levels when the rinsate reaches the pool — the impact on pool chemistry is minimal. Chlorine-based cleaning chemistry essentially adds a small amount of chlorine to pool water, which your pool system handles as a normal fluctuation.
However, we still take precautions: we avoid direct application of concentrated cleaning solution over the pool surface, we use the minimum effective concentration for the work required, and we recommend that you run your pool filtration during and after the service to circulate and dilute any rinsate that reaches the water. If you're particularly concerned, a standard pool chemistry test 24 hours after service will confirm your water is within normal parameters.
What Restored Screen Enclosures Look Like
The transformation from a professional soft wash is significant. Frames that looked dull gray-brown are restored to near-original color (typically bright white or bronze, depending on your enclosure). Screens that looked dark and opaque from algae colonization become transparent again. The overall enclosed space feels brighter and cleaner immediately after service.
Particularly dramatic results are common on enclosures that haven't been professionally cleaned in several years. Clients who use their pool area less during the heavy-growth summer months often return in fall to find their enclosure heavily colonized — and the soft wash transformation in those cases is dramatic.
How Often Should You Soft Wash Your Screen Enclosure in Fort Lauderdale?
For most Fort Lauderdale properties, annual screen enclosure cleaning is appropriate. Properties with heavy tree coverage, north-facing orientations, or close waterfront proximity may benefit from service every 6-9 months. The growth cycle in Fort Lauderdale's climate is fast enough that a one-year-old uncleaned enclosure can look significantly compromised.
Combining your screen enclosure cleaning with your annual house wash or roof cleaning service is the most efficient approach — the crew is already on-site, the chemicals are prepared, and you get comprehensive exterior results in a single visit.
Cost for Screen Enclosure Soft Washing in Fort Lauderdale
Screen enclosure soft washing is typically priced based on the enclosure's linear footage perimeter and height. Most standard single-story pool cage enclosures run $200-$400 as a standalone service. When bundled with a house wash or full exterior cleaning, the incremental cost is lower. Large lanai enclosures on two-story properties or oversized structures will be higher.
