Cleaning Guides
Tips to keep your composite decking looking its sparkling best.
Our composite decking comes with the reassurance of continual performance year-on-year . With a little care and attention, your boards will continue to look their vibrant best. This guide brings together the techniques we trust on every AGGTEDeck installation.
Foundation
Composite Decking Care Guide
Because of its aesthetic appeal and resiliency, composite wood has enjoyed its reputation as a popular decking material. As an additional feature, it requires minimal maintenance compared to other similar products in the market.
Like other wood varieties, composite decking is quite absorbent. Meaning to say, composite decks are prone to a wide range of outdoor elements like mold and mildew, black spots, sap, grease, oil, food spills, pet strains, hard water, grass stains, ground-in dirt and rust stains.
Oxygenated cleaners
Soft-bristled brush
Leaf blower or broom
When cleaning, it is best to use oxygenated cleaner that will penetrate deep into the material to clean both its inner and outer surface.
Avoid chlorine-based cleaners.
They are corrosive, discolor surfaces, and are unsafe near plants, children, or pets. If a product contains Sodium Hypochlorite, it contains bleach.
To preserve the beauty of the surface of the composite deck, sweep or blow away dirt and debris at least twice a week. For routine cleaning at least twice a year, follow the succeeding directions.
A regularly rinsed surface keeps the protective shell intact for decades.
Weekly rhythm
Your routine clean in three deliberate passes
We recommend refreshing your decking every three to six months to clear away accumulated dirt, mud, stains, and soil. A gentle weekly pass prevents everything from building up.
-
Sweep & rinse
Use warm, soapy water with a soft-bristled brush to loosen debris along the board grain.
-
Jet-wash mindfully
For deeper cleans, use a jet wash under 3100 PSI with the fan attachment at least 250mm from the surface.
-
Follow the boards
Always clean along the length of each board to keep drainage channels clear.
Pro tip: A handheld leaf blower makes quick work of dry leaves before they break down into stains.
Oil & grease
Stubborn spot stains disappear with quick intervention
For stubborn stains like oil and grease marks, reuse your routine cleaning approach and layer on these rapid-response moves.
Treat within 7 days
The sooner you address a spill, the easier it is to prevent shadowing. Blot gently before scrubbing.
Use water-based composite cleaners
Purpose-built cleaners lift oil without pulling pigment from the board’s protective shell.
Feather-light sanding
Only when necessary, sand lightly to remove the top surface layer. Color will even out as the board matures.
Stain response kit
Keep a kit ready with microfiber towels, composite-safe cleaner, and a soft sanding pad (220 grit) for quick touch-ups.
Residual oils
Water staining fades quickly with the right reset
Great care is exercised during manufacturing, but residual oils can occasionally appear as white streaks. They normally fade within 6–8 weeks of weather exposure, yet you can accelerate the process.
Speed up the fade
- Use warm, soapy water to cleanse the entire board face.
- Finish with a low-pressure jet wash to lift residues.
- Apply a composite decking brightener to neutralize lingering oils.
Need consistency? Treat the full deck section rather than spot-cleaning individual boards to avoid varied sheen.
Mould & mildew
Keep organic growth at bay with preventative habits
Our composite deck boards resist mould and mildew, yet damp planters, trapped leaves, and shaded corners can encourage growth. Regular upkeep prevents staining before it sets in.
Dry the base
Lift planters seasonally and wipe moisture from the contact points.
Promote airflow
Keep soft furnishings off the deck overnight to allow the boards to breathe.
Spot treat softly
Use diluted white vinegar or composite-safe cleaner, then rinse thoroughly.
Quarterly sweep-through
Inspect shaded corners and underneath planters, removing trapped soil before it compacts.
