Here is how to clean teak furniture without hurting it: rinse it with a garden hose, scrub with a soft nylon brush and mild dish soap in water, always moving with the grain, rinse again, and let it dry fully. That handles most routine dirt. Gray, mildewed, or stained teak needs a teak cleaner, sometimes a light sanding, and then a choice about whether to seal it.

First decide: let it gray or keep it golden
Untreated teak left outside weathers to a silvery gray. Country Casual Teak, a teak furniture maker, says this usually takes one to two years depending on sun and rain, and that teak kept indoors or under cover will not turn gray. Its FAQ says teak needs no preservatives to last outdoors.
Choose your look:
- Silver gray: clean it gently once a year and leave it alone. Least work.
- Golden honey: clean it, then apply a sealer with UV inhibitors and recoat every year or two.
Decide before you scrub: deep cleaning strips gray back to blonde.
How to clean teak furniture: routine wash
This is the method both Country Casual Teak and Castlery describe for regular cleaning.
- Clear it. Take off cushions and covers. Brush off loose grit with a soft brush or cloth.
- Protect the ground. Country Casual suggests a tarp, since cleaners can stain stone, concrete, or decking.
- Wet it down. Hose the furniture first.
- Mix a mild wash. Country Casual’s household recipe is two tablespoons of a mild cleanser, such as liquid dish soap, per gallon of water.
- Scrub with the grain. Use a soft nylon brush and gentle pressure.
- Rinse thoroughly, including undersides, so no soap film is left behind.
- Let it dry completely before putting cushions or covers back.
How often? Castlery suggests at least every few months, more in humid or dusty areas. Between washes, Country Casual recommends wiping spills right away and using coasters.
Deep cleaning mildew and stains
Black spots are usually mildew. Castlery suggests starting with equal parts water and white vinegar, or warm water and dish soap, scrubbed on with a soft brush (wear gloves), then rinsed. If the mildew has been there a while, both sources point to a commercial teak cleaner.
For grease from food or sunscreen, Castlery says to blot (not rub) the spill first, then scrub with mild detergent or teak cleaner. If a stain survives, a light sanding with fine grit paper in the direction of the grain can lift it.
Test any product on a hidden spot first, as Country Casual advises.
How to restore gray teak
To restore gray teak to its original blonde color, Country Casual describes an intense clean with a teak specific cleaner:
- Lay a tarp, put on gloves and eye protection, and wet the furniture.
- Apply the teak cleaner (they use a spray or squeeze bottle) and scrub firmly with a coarse sponge or nylon brush, with the grain.
- Rinse well. Two part cleaners have a second step applied while the wood is still wet, then another rinse. Follow the label.
- Let it dry. If the surface feels fuzzy or rough, sand lightly with 220 grit paper, with the grain.
To keep the gray, skip the teak cleaner and use the soap wash. Country Casual notes heavy scrubbing turns gray patches blonde, but they weather back.
Caution: Country Casual warns that sealers or paint on some prefinished teak may cover inferior wood, which deteriorates quickly if left bare. Check the maker’s guidance first.
Teak oil vs sealer: what the sources say
Castlery says teak oil can restore color, repel water, and bring out the grain, and also recommends a teak protector for added UV protection. Country Casual Teak advises against teak oil outdoors. They explain that most “teak oil” is linseed oil mixed with solvents, not oil from teak trees, and that it can turn sticky, collect dirt, feed mildew, and blacken in humid climates. They recommend water based sealers.
| Option | What it does | Upkeep | Watch out for |
|---|---|---|---|
| Leave untreated | Weathers to silver gray | Light annual clean | Gray look is permanent unless you deep clean |
| Teak oil | Darkens and enriches color for a while | Frequent reapplication | Sticky surface, mildew, blackening in humid areas (per Country Casual) |
| UV sealer (golden) | Holds the golden color | Recoat every 1 to 2 years | Must be applied to clean, fully dry wood |
| Clear protector (gray) | Resists stains and mildew, lets wood gray | Reapply as it wears | Does not stop graying |
Apply any product to clean, dry, dust free wood in thin coats, and check that cleaner and sealer are compatible.
What not to do
- No pressure washer. Both sources warn against it. Country Casual says it removes the soft wood between the grain, leaving a rough, furrowed surface that traps water and dirt.
- No steel wool or wire brushes. Country Casual notes metal flecks can lodge in the grain and rust.
- No bleach or ammonia. Castlery says harsh chemicals can strip the wood’s natural oils and color.
- Do not cover it wet. Let the furniture dry completely before covers go on.
Cushions, frames, and winter storage
The Benzara Ankia 5 piece outdoor dining set, listed at $1,047.42 at the time of writing, pairs teak wood with a dark gray aluminum frame. Rove Concepts uses teak slats or armrests on aluminum frames in the Francis Outdoor Coffee Table ($1,525) and the Linnea Outdoor Lounger ($629). Clean the teak as above and follow the maker’s guidance for frames and fabric. Our outdoor sectional guide covers protecting cushions.
Some teak comes prefinished. The Rove Concepts Coppola Outdoor Dining Chair ($363) lists teak wood with an oil-stained treatment, so stick to gentle soap washes. The Benzara Dena Outdoor Folding Armchair ($385.86) is listed as natural teak wood, and it folds for storage. Browse more from Benzara.
“Teak brown” can be just a color. The Benzara Lea Outdoor Dining Bench Set is varnished acacia in a teak brown finish, so skip teak cleaner and sanding on it.
For winter, Country Casual says teak handles snow, rain, and temperature swings. If you cover or store it, clean it first and make sure it is fully dry. For other materials, see our patio furniture material guide.

Frequently asked questions
What is the best way to clean teak furniture?
Hose it down, scrub with a soft nylon brush and mild dish soap in water along the grain, rinse, and let it dry fully.
How do you restore gray teak?
Scrub with a teak cleaner along the grain, rinse, and sand lightly with 220 grit if rough. Use a UV sealer to keep the blonde color.
Teak oil vs sealer: which is better outdoors?
Sources disagree. Castlery suggests oil can restore color. Country Casual Teak advises against oil outdoors because it can turn sticky, black, or mildewed, and recommends water based sealers.
Can I pressure wash teak furniture?
Both sources say no. High pressure can tear out the soft wood between the grain and leave a rough surface.
How often does teak furniture care need to happen?
Plan on a gentle clean every few months, a deeper clean about once a year, and resealing every one to two years if you keep the golden color.
