How to Clean Teak Outdoor Furniture (and Keep It Gorgeous)

When I first bought teak outdoor furniture, I knew that I was in for a treat. I wanted nothing more than to sit on my sun-drenched patio sipping iced coffee while enjoying the stunning natural beauty of the material. But your investment starts looking more like it comes from a haunted house than a leading landscape design magazine, you know you're in trouble. I knew that I needed to learn how to clean teak outdoor furniture quickly to avoid disappointment.

The good news is that cleaning teak is actually easier and simpler than you might imagine. Avoid pressure washes entirely, even if you use them for other landscaping elements and use a soft-bristle brush combined with natural cleaners like mild vinegar and dish soap instead (as I explain below).

I noticed that when I adopted this approach, it allowed me to maintain my teak dining set for much longer and avoid stripping away any of its natural charm. All I needed was to grab a brush and follow some tried-and-tested steps (which I outline below).

Understanding teak as a type of wood

If you're not familiar with teak, I recommend doing some research on it before you buy any outdoor furniture. Teak (as you’ll discover online) is one of the most durable types of wood, thanks to its naturally high oil content and tight grain, which makes it almost completely resistant to pests and rot.

Naturally, this is why so many homeowners use it outside. Not only does it tick all the usual cosmetic boxes, but it also avoids the problems of conventional outdoor wooden furniture.

Usually, UV rays damage the surface of wooden furniture over time, causing it to crack, lose its color, and blister. Teak has natural properties that prevent this from occurring and keep it looking fabulous all year round.

Teak is resistant to degradation because of the way it grows. As a species, teak had to survive in challenging environments where insect predators and the weather were a constant threat. Because of this, it developed ways to resist attacks from the outside, making it perfect for creating furniture for the outdoors today.

The ultimate step-by-step guide to cleaning outdoor teak furniture

So, now that you understand why teak is so prized, how do you clean it effectively?

Here are all the details:

Step one: Prepare and clear the area

Move your teak furniture to a shaded spot over grass or a piece of tarpaulin if necessary. Don't clean teak in direct sunlight, as it can cause cleaners to dry out too fast.

Step two: create your cleaning solution

For the cleaning solution, you have two options:

Mix 1 cup of white vinegar, 1 tablespoon of dish soap, and 1 gallon of warm water.
Use a specialized commercial product for cleaning teak.

Sometimes you can find eco-friendly two-part teak cleaners that don't contain any nasty chemicals. These protect your home as well as your community.

Step three: clean with the grain

The third step is to clean with the grain, not against it.

When cleaning teak, use a soft-bristled nylon brush or a Scotch-Brite pad. Don't use steel wool or high-pressure washers, as these can damage the surface of the teak and make it more susceptible to organic infiltration. Harsh cleaning erodes the teak's soft grain and ruins its smooth finish (which is probably the reason you bought it in the first place).

Step four: rinse and dry thoroughly

Finally, as you might guess, the last step is to rinse and dry your teak furniture thoroughly. Grab your garden hose and set the nozzle to a gentle spray setting. Once you remove all the cleaning fluid from the furniture, leave it to dry in the sun for 24 to 48 hours and apply protectants. Don't leave freshly-cleaned teak furniture out in wet weather.

The difference between deep cleaning and routine maintenance

Of course, how far you take your outdoor teak cleaning depends on your goal. There are different types of cleaning depending on the level of soiling.

Here's a table that explains more:

Cleaning Type	Frequency	Best For	Key Tools Used	Expected Outcome
Routine Light Clean	Every 3–6 months	Dust, pollen, minor spills	Warm water, mild dish soap, microfiber cloth	Maintains current look, prevents mold buildup
Deep Annual Clean	Once a year (Spring)	Stubborn dirt, graying layers	Vinegar solution or commercial teak cleaner, soft brush	Reveals fresh wood layer beneath weather film
Restoration Clean	Every 2–4 years (As needed)	Severe black mold, deep stains	Heavy-duty two-part teak cleaner, light 220-grit sandpaper	Restores silvered teak back to its original golden hue

For restoration cleans, you may want to go beyond the simple cleaning techniques discussed above. Restoration may require professionals to sand the wood and then re-apply sealants. It may also just require more elbow grease, as we explain below.

Should you oil, seal, or leave your teak furniture alone?

When I first decided to clean my teak outdoor furniture, I stumbled across the online debate over whether to “seal” or “oil” teak furniture. If I'm being direct with you, I didn't know which option was best.

Teak oil is actually a misnomer. Usually, the oil in teak is from linseed or tung oil mixed with various solvents.

Unfortunately, oiling outdoor teak can encourage mold growth by creating a feeding ground for spores. These travel through the air and land at random on the teak, using any substrates already present to grow and multiply.

Because of this, I recommend using a sealer over oil if you want your outdoor teak furniture to maintain its golden color. Sealers protect against UV light while also preventing mold from getting a foothold.

If you've recently purchased a modern piece of teak furniture, like one of our outdoor dining sets, using a premium water-based sealer will lock in that showroom-ready warm glow. Your teak furniture will look the same as it did the day you bought it if you maintain a proper maintenance schedule, even if you leave high-end pieces outside for months at a time.

How to choose and maintain your teak pieces

Choosing and maintaining your teak pieces is simpler than you might think. Here's what to do:

Check the grade. Make sure that any furniture you choose is classified as Grade A teak for outdoor furniture. This type of teak is made from the trees' mature hardwood and is richest in natural protective oils. Grades B and C teak contain more sapwood (the outer portion of the tree trunk) and are softer and don't last as long outdoors.
Winterize your teak pieces. Don't wrap teak in plastic tarps during winter, because this traps moisture and causes mildew. Use breathable furniture covers instead, and then store your chairs and tables in an unheated shed.
Look for solid construction only. Choose beautifully crafted pieces of teak furniture, like those in Homary’s luxury teak range.

How to deep-clean outdoor teak furniture

Sometimes you may need to deep clean outdoor teak furniture. Usually, the best option is to go to a professional, but you can also take a DIY approach.

Here’s what to do:

Prepare and saturate the wood. Take your wood to a shady area and hose down the entire piece with clean water.
Apply the solution. Use a commercial or professional solution designed to deeply infiltrate the material and kill off any mold or other organics that may be present.
Scrub gently for up to half an hour, always in the direction of the wood grain. The more passes you make on the wood, the more ingrained dirt and grime you are likely to clean.
Hose down and leave to dry for 48 hours. The more drying time you allow, the more you will protect the wood.

Frequently asked questions

Can I use a pressure washer to clean outdoor teak furniture?

I would strongly advise against using a pressure washer to clean your outdoor teak furniture. Intense pressure can gouge the wood and damage the delicate surface structure that gives teak its protective properties. If you do damage the exterior with a pressure washer, it can require extensive sanding to fix.

How do I remove black mold spots from teak furniture?

You can remove black mold spots from teak furniture using several methods. I like to mix 1 cup of household bleach, 1 cup of laundry detergent, and a gallon of water together. This combination is exceptional at killing off the natural fungal spores that lead to mold growth.

When applying this mixture, allow it to sit for up to 10 minutes and then rinse thoroughly. Do not let it remain on the wood for too long, because it can cause damage.

Does vinegar damage teak?

Diluted white vinegar won't damage your teak. It's also highly effective at killing mold spores if you want to avoid using bleach and is safe for the natural oils the wood contains.
