Wooden parts are made of teak wood which is impregnated with teak oil. Due to prolonged stay in extreme conditions while shipping, it is necessary to treat the wooden parts with teak oil again within one month of delivery. We recommend using the teak oil SWINGEAT OIL from our range. Further on, we treat the wood with teak oil as necessary, but at least once up to three times a year. Otherwise, the wood dries up and the original hue turns to a silver-grey patina. When treating the wood, follow the instructions of the producer/distributor of the teak oil as stated on the package.
