Dust regularly or wipe with a slightly damp cloth. Allow to air dry. Balau wood should be treated with a solution of 10 parts Linseed Oil mixed with 1 part Turpentine. Regularity of application will depend on exposure to sunlight, sea air, swimming pool chemicals and weather elements. Cracks may appear and timber movement is natural due to wood being a living, natural material. Never use harsh chemicals to clean spots and spills. This wood has inherent resin (oil) content. Even with treatment, resin still remains inside the wood. After exposure to UV rays and normal South African weather conditions, small dark spots could appear. These spots appear as the oil is being pushed out of the wood to the surface.
