How do I clean decking?

It depends on the issue with the deck. If it's simply dirt, debris and plant matter, decking can be cleaned by sweeping with a stiff bristle broom then treated with a dedicated decking cleaner. For decking that has been affected by mould and algae, sweep with a stiff broom or brush to remove as mush surface matter as possible then treat with a mould and mildew cleaner. heavily soiled decking may require a second treatment.
