Composite cladding is a modern, low-maintenance alternative to traditional timber cladding — engineered for durability, weather resistance, and a consistent finish. However, like any exterior material, it benefits from regular care and attention to keep it looking its best and performing well over time.
This guide explains how to care for composite cladding, outlines practical cleaning routines, offers stain-removal tips, covers seasonal checks, and highlights common maintenance mistakes to avoid — especially in varied climates like Australia’s.
Why Care Still Matters (Even for Low-Maintenance Cladding)
Composite cladding is designed to be more resilient and easier to maintain than wood, but it isn’t completely maintenance-free. Periodic cleaning and inspection help:
-
Prevent dirt, pollen and grime build-up
-
Maintain colour and aesthetic appeal
-
Avoid mould, mildew or surface staining
-
Ensure joints, trims and ventilation gaps remain clear
With the right care, your cladding can continue to look fresh and perform for decades.
Basic Cleaning Routine (Twice a Year)
A simple cleaning routine keeps composite cladding free of most everyday dirt and debris:
🧼 Tools & Materials
-
Soft-bristle brush or soft cloth
-
Warm water
-
Mild, biodegradable detergent
-
Garden hose or low-pressure rinse
🧹 Step-by-Step Cleaning
-
Dry brush loose dust and debris from the surface.
-
Mix warm water with a mild detergent.
-
Gently scrub the cladding in the direction of the board grain with a soft brush or cloth.
-
Rinse thoroughly with clean water to remove all residue.
-
Allow the cladding to air dry naturally.
Frequency: At least twice a year (spring and autumn); more often in coastal or urban environments with increased airborne debris.
Seasonal Maintenance Tips
Spring & Summer
-
Light cleaning prepares the façade for drier months.
-
Remove pollen, dust and early stains before the heat sets in.
After Rain / Winter
-
Clear mud, leaf debris and organic material that can trap moisture.
-
Clean off mildew and other moisture-related marks.
Autumn
-
Remove leaf litter from trims, ventilated cavities and drainage paths to maintain airflow.
Good airflow and clean trims help prevent moisture from becoming trapped, which can lead to surface stains or algae growth.
Stain & Mark Removal
Composite cladding resists many stains, but handling marks promptly helps keep a clean appearance:
Everyday Dirt & Grime
Use warm soapy water and a soft brush to lift surface marks — rinse thoroughly afterwards.
Grease or Oil Marks
Apply a diluted, pH-neutral, outdoor-use degreaser. Test on a small, inconspicuous area first.
Water Streaks / Mineral Marks
Use a soft cloth with a mild vinegar solution (diluted), then rinse top to bottom.
Avoid Harsh Cleaners
Do not use harsh solvents, abrasive pads, wire brushes, undiluted bleach or strongly alkaline cleaners. These can damage protective surfaces.
Pressure Washing — Use With Caution
While low-pressure rinsing can help with larger jobs, avoid high-pressure jets near the surface, as they can damage board edges or trims. Keep the nozzle 30–40 cm away and work at an angle if using a pressure washer.
Inspect Regularly & Check Joints
Maintenance isn’t just about cleaning — it’s also about ensuring the system functions as a whole:
-
Check fixings and trims for security
-
Clear debris from joints, drip edges and ventilation gaps
-
Look for signs of trapped moisture around window reveals or base edges
-
Confirm that ventilation cavities remain open for airflow behind cladding boards
Regular inspections help catch minor issues before they become costly repairs.
Life-Cycle & Durability
Composite cladding is engineered for long life and colour stability:
-
Some natural wood oils (tannins) can appear as water marks early in exposure, but usually fade after rain and drying cycles over weeks to months.
-
UV-stable formulations help minimise fading.
-
Boards typically stabilise in colour after initial weathering.
With basic care and normal weathering, composite cladding retains its appearance and performance far better than many traditional materials.

At PureSolid, our composite cladding systems are selected for weather resilience, colour stability and long-term, low-maintenance performance — ideal for Aussie conditions, whether coastal humidity or inland heat.
Because maintenance is straightforward — mostly simple cleaning and inspections — our products help you spend time enjoying your home’s exterior, not maintaining it.
For product-specific care guidance, always refer to the installation and maintenance guide provided with your cladding, or reach out to the PureSolid support team for tailored advice.
Frequently Asked Questions
How often should I clean composite cladding?
Clean at least twice a year, and more often if you’re near the coast or in a dusty environment.
Can I remove mould or mildew?
Yes — regular cleaning with warm soapy water and a soft brush will prevent and remove surface mould before it becomes visible.
Is pressure washing safe?
Low-pressure rinsing is okay, but keep the nozzle at a safe distance from the surface and avoid high-pressure jets, which can damage edges.
Do I need to seal or repaint composite cladding?
No. Composite cladding does not require sealing, painting or staining, unlike timber products, saving time and money over the long term.
Final Thoughts
Caring for composite cladding isn’t difficult — but it does benefit from a consistent approach. With the right routine, quick stain response and regular inspections, your cladding will continue to look great and perform well for years.
