Teak is a very dense and oily wood. The natural oil present within teak wood offers it protection from pests such as termites. The oil also keeps water from seeping into the wood. This means teak furniture can be left outside and endure years of rain, wind, heat, and cold. If the furniture was skilfully crafted it will last for generations.
Teak wood has a golden honey colour when new, but after time it naturally fades into a light gray patina. This colour change is only cosmetic and does not affect the strength of the wood. But if you prefer the golden colour there are a couple things you can do to slow down the aging process.
Most teak furniture makers recommend not using teak oil - and we definitely agree! The wood’s natural oil is sufficient to protect it from damage. Teak oil is not actually the same as the natural oil found in the teak tree. It is just called “teak oil” for marketing purposes & is actually not good for the integrity of the wood.
We recommend instead to use a treatment with teak sealer such as Semco Teak Sealer if you'd like to maintain the natural honey colour. This is only needed once a year in order to effectively protect teak wood from colour fade. And if later you decide to let the furniture fade naturally to grey, teak sealer treatments can simply be discontinued. After not applying sealer for a while, the wood will simply begin to age as before.
Since teak sealer is more effective at preserving the colour of teak wood, and it only requires a few hours of your time each year to apply, it is recommended over teak oil.
Teak is very durable and will last for generations. It only needs some basic cleaning to remove dirt and to prevent external mould growth. You should choose a sunny day to clean your teak furniture so that it will dry faster. It is recommended to use a specially formulated teak cleaner such as Golden Care Teak Cleaner, which will clean and brighten the wood at the same time. Soapy water will also suffice for basic cleaning.
