Teak contains its own protective oils, which is why it survives outdoors untreated. Almost every teak problem we see is caused by maintenance, not by weather.

Wash once a year

Warm water, a little soap and a soft brush along the grain in spring. That is the whole routine for furniture you are happy to let silver.

Skip the teak oil

Oil feeds surface mould and produces the black blotching people mistake for rot. If you want the honey colour back, use a teak sealer after cleaning — not oil.

Sand, do not strip

A light pass with 120 then 180 grit removes years of greying in minutes and leaves the surface fresh.

Lift it off the ground

Feet standing in a puddle wick water upward. Small pads or a slatted surface prevent the only genuine rot risk teak has.

Frequently asked

Can I pressure wash teak?
Only on a wide fan at low pressure and never close up. High pressure erodes the soft summer grain and leaves a permanently furry surface.
Is grey teak damaged?
No. The silver patina is a surface layer a fraction of a millimetre deep and has no effect on strength.
