Yes. Teak is one of the few woods that can be left outdoors year-round in most U.S. climates.
Over time, it naturally develops a silver-gray patina, which does not affect its strength or durability.
Does teak furniture need oiling?
Not necessary.
Teak naturally contains oils that protect the wood.
If you want to keep the golden-brown color, you may apply teak oil or sealer
If you prefer a natural weathered look, no oil is needed
