Grip-safe composite deck cleaning in BD18
Film build-up, mould spotting and grip loss on composite boards.
The tell on a BD18 composite deck is a matte cast across shaded boards near a mill-worker cottage — that's biofilm, not fade.
We work Saltaire and the surrounding BD18 postcodes every week, so a Composite decking job here is a scheduled call, not a special trip.
What we use, and why
Composite-safe neutral cleaner plus a low-concentration biocide on shaded runs — no aggressive alkalis, no hot rotary passes.
How we clean composite decking
sweep board gaps clear so water and cleaner can drain
soft-wash with a composite-safe cleaner and low-pressure rinse
brush along the manufactured grain to lift the biological film
clean-water rinse and dry with no residue left behind

Defining traits in Saltaire
- hidden clip fixings with narrow board gaps
- capped or uncapped surface layer
- wood-plastic composite board with a factory-formed grain
- long-life colour retention with lower maintenance than softwood
Keeping it right
Sweep monthly, keep planters off the boards, and give the whole deck a soft-wash every 12–18 months in shaded gardens.
When to book
Any month — composite handles cold cleaning fine; dry conditions just give a nicer finish.
Typical use: new-build decks, hot-tub surrounds, roof terraces, premium garden rooms.
