Teak: Long-term, teak furniture develops a pleasing silvery gray patina, which is cosmetic and not an indication of dryness. Its natural oils help keep this hardwood strong and durable in a variety of environments, so there's very little maintenance. Because teak is very weather-resistant, it doesn't need to be stored during the winter or covered with protective tarps. However, covering teak furniture will protect the surface from elements such as hail, wind, and snow, which can cause cosmetic damage. To keep the original golden honey finish, apply a very thin layer of Linseed or Teak oil to your furniture 1-2 times a year, depending on exposure. Cleaning with teak cleaner is recommended every 2-3 years, along with the oil application.
