Teak is one of the hardest, strongest and most durable of all woods, highly resistant to rotting and almost impervious to the effect of sun, rain, frost or snow. These characteristics make it the ideal wood for outdoor furniture as it can be left outside uncovered all 12 months of the year. The first plantations on the island of Java were planted by the Dutch and are now owned by the Indonesian government. Only a limited number of trees each year are allowed to be felled and an equal amount of reforestation ensures there is no detrimental effect to the country's natural resources. Teak is a unique and durable hardwood which requires little or no care. If you prefer your teak, like many do, in its natural state which is a graceful silver grey colour, then you literally have to do nothing. Teak, unlike other hardwoods, does not need any oiling, staining, lacquering or painting to keep healthy and maintain its durability. Treating the teak is only recommended if you prefer the golden yellow colour of the wood. Whether to oil or not, is purely a personal choice, doing either will not harm or detract from the strength or durability of the wood. The only maintenance recommended for teak furniture is occasional cleaning. This should be done with a mild soap (such as gentle hand cleaning soap) and warm water to preserve its natural elements. Teak (Tectona grandis), is one of the most valued woods in the world, and grows in areas between the Tropic of Cancer and the Tropic of Capricorn. Teak trees can grow up to 150 feet tall and have large, leathery, reddish green leaves that are shed in the drier months of the year. Teak's sap has natural anti-bacterial and anti-fungal properties that make it resistant to parasites and disease. Teak also contains rubber and silica, which repel water. The wood also has great pliability, making it better able to withstand high pressure without cracking.
