Timber and composite
Softwood timber needs a gentle approach so the grain isn't raised or furred. Composite decking can take a firmer clean. I adjust the method to suit your deck.
Questions about decking cleaning
Why is my decking so slippery?
Algae and moss build up in the grooves, especially in shade. Once they are cleaned off, the deck has its grip back.
How often should decking be cleaned?
Once a year is enough for most decks. Shaded decks under trees may need it more often.
Do you clean composite decking?
Yes, both timber and composite.
