20 Best Cleaner For Composite Deck (2022 Updated)

Composite decking is made from a mix of recycled plastic and wood fibres. It is a popular choice for decking because it requires less maintenance than traditional wooden decking and it is also more durable and longer lasting.

There are a few things you can do to keep your composite decking clean and looking its best. First, sweep it regularly with a broom to remove any dirt or debris. You can also use a garden hose to rinse off your deck.

If you notice any stains, you can use a mild soap and water solution to spot clean them. Finally, be sure to regularly check for mould or mildew and clean it as soon as you see it.
