Clean wooden deck

After installation, a wooden decking can develop oxidation spots after contact with base metals or over time dirt, moss and fungi can accumulate. Dirt is not only unsightly, it can also affect the life of the decking. If the wood color is to be renewed, the decking boards should be treated again with decking oil after cleaning. Do not use high-pressure cleaners, metal brushes or chemical cleaners that have not been tested by us.
