Teak stays beautiful with regular cleaning and occasional oiling, but it needs different care than other wood furniture
Teak is naturally resistant to rot, insects, and weather because it contains oils that protect the wood from the inside. That said, teak still needs maintenance. Left completely untouched, it will turn silver-gray over time—which many people like—but the wood can crack if it dries out too much, especially in very hot or dry climates. The good news is that teak care is straightforward: wash it regularly, oil it once or twice a year, and deal with mold or mildew as soon as you spot it.
How much work you do depends on how you want your furniture to look. If you like the silver-gray weathered appearance, you can do almost nothing except wash off dirt and leaves. If you want to keep the warm honey color, you'll need to oil it regularly. Either way, the furniture will last 15 to 20 years or longer if you keep water from pooling on it and don't let mold take hold.
Key Takeaways
- Wash teak furniture with plain water and a soft brush or cloth every month or two to prevent mold and mildew from taking root.
- Oil the wood once or twice a year with teak oil or Danish oil to keep the warm color; skip oiling if you prefer the natural silver-gray patina.
- Never use pressure washers, bleach, or harsh cleaners on teak, as they damage the wood and strip away the natural protective oils.
- Remove standing water from flat surfaces and may support cushions dry completely after rain to prevent rot and mold underneath.
- Sand rough spots lightly with fine-grit sandpaper if the wood splinters, but avoid sanding the whole piece unless you are refinishing it.
Wash teak furniture every month or two with water and a soft brush
The most important maintenance step is regular washing. Dirt, pollen, and organic debris trap moisture against the wood, which is where mold and mildew start. Use plain water from a garden hose or a bucket, a soft-bristled brush (or an old toothbrush for crevices), and a cloth. Scrub gently in the direction of the grain, then rinse thoroughly and let it air dry.
If you see dark spots or a greenish tint—signs of mold or mildew—mix one part white vinegar with three parts water and scrub the affected area with a soft brush. Rinse well and let it dry completely. Do this as soon as you notice it; mold spreads quickly in humid climates. If the mold is stubborn, you can use a commercial teak cleaner, but follow the label directions and rinse very thoroughly afterward.
Never use a pressure washer on teak. The force of the water drives moisture deep into the wood and can splinter the surface. Bleach and harsh chemical cleaners will also damage teak by stripping away the natural oils that protect it.
Oil the wood once or twice a year to maintain the warm color
Teak oil or Danish oil are the standard choices for keeping teak looking rich and honey-colored. You do not have to oil it—teak will weather to a beautiful silver-gray on its own—but oiling slows that process and keeps the wood looking newer. explore oil once in spring and once in late summer, or once a year if you live in a mild climate.
Before oiling, make sure the furniture is clean and completely dry. Wipe the surface with a cloth to remove any dust. Pour a small amount of oil onto a soft cloth and rub it into the wood in the direction of the grain, using light pressure. Work on one section at a time. Let the oil soak in for 15 to 20 minutes, then wipe away any excess with a clean, dry cloth. The wood should look slightly darker and feel smooth, not slick or sticky.
If you skip oiling, the wood will still be protected by its natural oils—it will just turn gray faster. Many people prefer this look and choose not to oil at all. Either choice is fine; it is purely about appearance.
Prevent water from pooling and keep cushions dry underneath
Teak resists rot better than most woods, but standing water is still a problem. After rain or watering, wipe off any water that collects in corners, on seat surfaces, or in grooves. If your furniture has cushions, remove them and let them dry separately so air can circulate underneath the wood. Wet cushions trap moisture against the frame and can cause mold to grow on the underside where you cannot see it.
If you store cushions indoors during winter or rainy season, make sure they are completely dry first. Damp cushions stored in a closed space will develop mold. Store them in a dry place with good air circulation, or use breathable storage bags rather than plastic ones.
Sand lightly if the wood splinters, but avoid refinishing unless necessary
Over time, especially if the wood is exposed to intense sun or very dry air, small splinters may appear on edges or armrests. If they are rough enough to catch your hand, sand them lightly with fine-grit sandpaper (220-grit or higher) in the direction of the grain. Sand only the splintered area, not the whole piece. Wipe away the dust with a damp cloth and let it dry, then oil that spot if you have been oiling the furniture.
Do not sand the entire surface unless you are doing a full refinish, which is a bigger project. Light spot-sanding is fine; heavy sanding removes the protective patina and opens the wood to more damage.
Protect teak from extreme heat and direct sun if possible
Teak can handle sun and heat, but intense, constant exposure speeds up the weathering process and can cause the wood to crack if it dries out too quickly. If you live in a very hot or dry climate, position furniture in partial shade when you can, or use an umbrella or shade sail nearby. This is not essential—teak is made for outdoor use—but it will slow the graying and reduce the risk of checking (small cracks in the surface).
In winter, you do not need to cover teak or bring it inside unless you live somewhere with freezing temperatures and heavy snow. Teak handles cold well. If you do cover it, use a breathable cover that allows air to circulate; plastic covers trap moisture and promote mold.
Deal with stubborn stains and discoloration
Rust stains from metal hardware or nearby objects can appear on teak. If you see rust, scrub the area gently with a soft brush and white vinegar, or use a commercial rust remover made for wood. Test it on a hidden spot first. Rinse thoroughly and let it dry.
White water marks or mineral deposits from hard water or sprinklers can usually be removed by scrubbing with a soft brush and vinegar solution, then rinsing well. If the mark is deep in the wood, it may not come out completely, but it will fade over time as the wood weathers.
Ink, wine, or other stains may lighten with scrubbing and vinegar, or they may be permanent. Teak's natural color variation means small stains often blend in as the wood ages.
Frequently Asked Questions
Can I leave teak furniture outside year-round?
Yes. Teak is designed for outdoor use and handles rain, snow, and temperature swings well. You do not need to cover it or bring it inside unless you live in an extreme climate. Leaving it out actually helps it weather evenly. If you do cover it, use a breathable cover, not plastic.
What is the difference between teak oil and Danish oil?
Teak oil is formulated specifically for teak and often contains teak-specific additives. Danish oil is a general-purpose wood oil that works well on teak too. Both protect and enhance the color. Danish oil is usually cheaper. Either one works; choose based on price and availability.
Why is my teak turning gray, and is that bad?
Teak turns gray naturally as the sun bleaches the outer layer of wood. It is not damage—it is weathering. The wood underneath is still sound. If you like the gray look, do nothing. If you want the warm color back, oil it regularly or sand the surface lightly and re-oil.
Do I need to seal teak furniture?
No. Teak has natural oils that protect it, and sealers can trap moisture underneath and cause problems. Just wash it and oil it if you want to keep the color. Sealing is not necessary and not recommended.
What should I do if mold keeps coming back?
Mold returns when the furniture stays damp or is in a very humid, shaded spot. Wash more often, make sure water drains away, and if possible move the furniture to a sunnier location with better air circulation. In very humid climates, oiling more frequently can help, since the oil slows moisture absorption.
