Teak is one of the most forgiving outdoor materials you can own — but “low maintenance” doesn’t mean “no maintenance.” The good news: caring for teak outdoor furniture takes about an hour once a year, and the steps are far simpler than most people expect. This guide covers everything from routine cleaning to the great teak oil debate, so you can make informed decisions and keep your furniture looking exactly the way you want it.
Before diving into maintenance steps, it helps to understand what makes teak different from other outdoor woods.
Teak (Tectona grandis) produces abundant natural oils and silica within the wood grain. These compounds work together to repel water, resist insect infestation, and prevent the rot that destroys softer woods within a few seasons outdoors. This is especially true of old-growth and reclaimed teak, where decades of slow growth have produced a denser, oil-richer timber.
Why aged teak outperforms new wood →
The most common concern new teak owners have is the colour change. Fresh teak is a warm honey-brown. Left outdoors, UV exposure oxidises the surface oils and turns the wood silver-grey within 6–12 months. This is a surface-only process — structurally, the wood is completely unaffected. The patina is self-maintaining and actually helps protect the underlying wood.
Your maintenance approach depends largely on which colour you prefer:
Neither is wrong. Both are valid long-term strategies.
Cleaning removes surface grime, algae, mildew, and bird droppings that accumulate over the season. This is the one non-negotiable step regardless of whether you oil or not.

What to avoid during cleaning:
After cleaning and drying, you face the key decision. Here’s an honest breakdown:
| Approach | Appearance | Effort | Risk |
|---|---|---|---|
| No treatment | Silver-grey patina | Lowest | None |
| Teak oil annually | Warm honey-brown | Moderate | Mildew if over-applied |
| Teak sealer | Brown, more uniform | Moderate | Harder to reverse |
If you choose to oil: Use a purpose-made teak oil (linseed-based blends with UV inhibitors), not raw linseed oil or generic wood oil. Apply with a clean cloth along the grain. Wipe off excess after 15–20 minutes — oil left to pool on the surface is the primary cause of mildew on teak. One coat is typically sufficient.
If you choose not to oil: Do nothing after cleaning. The wood will naturally re-patina to silver-grey. This is the approach preferred for reclaimed teak, which already has decades of natural oil in the grain and needs no supplementation.
Teak furniture joints expand and contract with seasonal temperature and humidity changes. A quick annual inspection prevents minor loosening from becoming structural damage.
Check:
Stainless steel hardware (grade 316) won’t rust. If you see rust, the original hardware was not marine grade — replace it.
Teak doesn’t need to come indoors for winter — it is fully outdoor-rated year-round. However, if you have the storage space, store flat or stacked with breathable covers between pieces. Avoid plastic sheeting directly on the wood (traps moisture) and ensure good air circulation wherever stored.
The most frequent mistake. Applying teak oil too frequently — monthly or even quarterly — saturates the surface faster than it can absorb. The excess oil sits on the surface, traps moisture, and feeds mildew. Once a year (or less) is the correct frequency for established teak.
Raw linseed oil, olive oil, and generic “wood oil” are not suitable for outdoor teak. They go rancid, attract insects, and don’t contain the UV inhibitors that slow re-graying. Use a product specifically labelled for teak.
Even on a low setting, pressure washing drives water deep into the grain, swells the wood fibres, and physically strips natural oils. A garden hose and soft brush achieves the same cleaning result without the damage.
Waterproof covers that trap moisture underneath cause more problems than they solve — including mildew, moisture damage to joints, and rust on any metal components. If you use covers, choose breathable canvas-type covers with vents.
Some guides recommend annual sanding. This is unnecessary for sound teak and removes the patina and surface oils you want to keep. Sand only if there are raised grain issues, splinters, or surface damage — and always with the grain, using 120–180 grit sandpaper.
Once a year is sufficient for most outdoor teak furniture. If the furniture is in a high-traffic area, near a pool (chlorine splash), or under trees, a second light clean mid-season may be worthwhile.
Generally no — or very rarely. Reclaimed teak from old-growth sources already contains high concentrations of natural oils built up over decades. Additional oil is usually unnecessary and can cause surface mildew. Clean it and let the patina develop naturally.
No. Pressure washing strips natural oils, raises the wood grain, and can damage joints. Use a garden hose on a gentle setting combined with a soft brush.
Mix 1 part white vinegar with 4 parts water. Apply with a soft brush, scrub gently along the grain, and rinse thoroughly. For stubborn spots, a dedicated teak cleaner is more effective than household alternatives. Avoid bleach.
Yes. Clean the furniture thoroughly and allow it to dry completely (minimum 48 hours). Then apply one coat of quality teak oil along the grain, wiping off excess within 20 minutes. The colour will return to warm brown within a few hours of application. Expect to repeat annually to maintain the colour.
Caring for teak outdoor furniture is genuinely straightforward: clean it once a year, decide whether you want brown or silver-grey, and address spills and hardware checks as needed. There’s no stripping, staining, or complex refinishing required. With even minimal attention, quality teak furniture — especially reclaimed old-growth pieces — will remain structurally sound and beautiful for decades.
