When it comes to caring for outdoor wood and wood surfaces, we advise that a light cleaning of the wood should be provided with a cloth that is damp as well as an outdoor wood cleaning solution. Deep cleaning should be carried out once a season and this will cover getting rid of tough stains like mold, this should be scrubbed with a soft brush and a mix of water and a wood cleaning solution. We recommend scrubbing in the direction of the wood grain and then any tougher stains can be removed by light sanding of the area and then rinsing the surface.
