Every week someone asks us whether they've ruined their teak because it's "gone grey". The short answer: no. The longer answer is that teak gives you a choice most outdoor materials don't, and it helps to make that choice on purpose rather than by accident.
Why teak grays in the first place
Teak is loaded with natural oils and rubber, which is why it survives decades outdoors when other timbers rot. What changes over time is only the surface. UV light breaks down the outer layer of oils, and the top half-millimetre of timber turns a soft silver-grey. Underneath, the wood is as sound as the day it arrived. Run a light sand over a ten-year-old grey teak bench and you'll find golden timber straight beneath the surface.
Option one: let it silver
This is the low-effort path, and honestly the one many designers prefer. Weathered teak has a relaxed, coastal look that suits Australian gardens well. If you go this way, your only jobs are cleaning and the occasional check of fittings. Wash it once or twice a year with warm soapy water and a soft-bristled brush, scrubbing lightly along the grain, then rinse. That's it. The greying is even and gradual as long as the piece sits fully in the weather; furniture half-under a pergola can silver patchily, which is the one situation where we'd suggest either moving it or committing to oil. A teak Adirondack is a good example of a piece that usually sits fully exposed and silvers evenly, and we weigh that finish up against the moulded plastic replicas in our guide to whether Adirondack chairs are worth it in Australia.
Option two: keep it golden
If you love the warm honey tone teak arrives with, you'll need to feed it. Clean the piece first, let it dry completely (a full dry day, minimum), then apply a quality teak oil or timber protector with a cloth or brush, working along the grain. Wipe off any excess after fifteen minutes so it doesn't sit sticky. In most parts of Australia you'll be doing this every six to twelve months — more often in Queensland sun, less in shaded positions. If you're weighing that oiling routine against a no-oil alternative before you buy, our comparison of the ten-year cost of a teak outdoor dining table versus aluminium sets the two upkeep routines side by side. If you're buying for a humid subtropical climate in the first place, our guide to teak outdoor lounges in Queensland and on the NSW North Coast explains how the timber performs there and what oiling schedule to plan for. Miss a year and nothing terrible happens; the timber just starts drifting towards grey and the next oiling brings it most of the way back. Folding pieces are the easiest of all to keep golden, because you can carry them somewhere shaded and lay them flat — our guide to teak folding chairs for Australian homes walks through that routine.
What actually damages teak
The grey patina is cosmetic. These things aren't:
Pressure washers. They chew the soft grain out of the surface and leave it furry. Soapy water and a brush, always.
Trapped moisture. A non-breathable tarp thrown over timber for winter traps condensation against the surface and invites mould. If you cover teak, use a proper ventilated furniture cover and make sure the piece is dry first.
Loose joints left loose. Timber moves with the seasons. Once a year, go around the bolts on your bench or dining table with a spanner and snug up anything that's worked itself free. Two minutes of maintenance prevents the slow wobble that eventually stresses joints.
Small black spots? Don't panic
Dark speckling on teak is usually mildew sitting on the surface, not rot. A wash with diluted white vinegar (about one part vinegar to four parts water), a soft scrub and a rinse deals with it. Rot in genuine teak is vanishingly rare — if a piece ever feels spongy, it's more likely a cheaper timber sold as "teak-look", which is a different conversation.
A note on new furniture
Fresh teak sometimes weeps a little of its natural oil in the first weeks, especially in summer, and can leave marks on porous surfaces like fresh concrete. Slip something under the feet for the first month if your alfresco slab is new. It settles down on its own. Kwila bleeds tannins far more heavily and needs bleeding on grass before it touches paving, as our guide to kwila outdoor furniture and how it compares to teak explains.
Whichever path you pick, teak rewards you for decades. It's one of the few materials where "doing nothing" is a legitimate care strategy — you just end up with a different, equally good-looking piece of furniture. Browse our timber tables, chairs and benches, and if you're unsure how a particular piece is finished, ask us before you order — happy to check the details.
