A Guide To Cleaning Teak Outdoor and Patio Furniture

Teak outdoor furniture is a popular choice for many homeowners due to its durability, strength, and beauty.  

However, like any outdoor furniture, it’s exposed to the elements and can accumulate dirt, grime, and even mould. Regular cleaning and maintenance are essential to keep your outdoor furniture looking its best and prolong its lifespan. 

In this article, we’ll provide you with the best practices and a step-by-step guide on how to clean teak outdoor furniture effectively.

A step-by-step guide on how to clean teak outdoor furniture

Step 1: Clear the furniture

Remove any cushions or fabric covers from your furniture and place them aside. Then, clear the furniture of any debris or dirt using a soft-bristled brush or a cloth.

This initial clearing is crucial as it prevents scratching the wood during the washing process and ensures that the cleaning agents can work directly on the wood's surface.

Step 2: Mix the cleaning solution

In a bucket, mix warm water with a mild detergent, or use a natural cleaning solution, such as vinegar or baking soda. If you're using a natural solution, mix one-part solution with three-part water.

When cleaning teak furniture, you’ll want to avoid using harsh chemicals or bleach as they can damage the wood.

Step 3: Gently scrub the furniture

Dip a soft-bristled brush or a clean cloth into the cleaning solution and scrub the furniture, paying extra attention to any areas with visible dirt or stains. Be gentle but thorough, and avoid scrubbing too hard as this can damage the wood.

Step 4: Rinse the furniture

Using a hose or a bucket of clean water, rinse the furniture thoroughly to remove any soap residue. Make sure to rinse all areas, including the undersides of the furniture. Avoid using a pressure washer as it can damage the wood and strip away its natural oils.

Step 5: Allow the furniture to dry completely

Leave the furniture in a well-ventilated area to dry completely. Avoid using a dryer or placing the furniture in direct sunlight as this can cause the wood to warp or crack.

Step 6: Reassemble the furniture

Once your teak furniture has dried down completely, you can reassemble it and replace any cushions or covers.

Step 7: Sand down the furniture

Optionally, you can also sand down your furniture or apply teak oil during this process. If your teak furniture has any stubborn stains or discolouration, you can sand it down with fine-grit sandpaper.

Likewise, if you feel that your teak furniture is looking a little faded, you can restore its natural shine by applying teak oil with a soft brush or clean cloth. 

Best practices when cleaning teak furniture

Maintaining teak furniture is more than just a chore—it's a way to preserve and enhance its natural beauty and longevity. By adopting the right cleaning habits, you ensure your outdoor spaces remain inviting and elegant. Here’s how to approach cleaning with care and effectiveness.

Clean your teak furniture regularly

Regular cleaning is the key to keeping your teak furniture looking its best. Dust and debris can accumulate on the furniture over time, leading to discolouration and staining. Try to clean your furniture at least every few months, or more frequently if you live in a humid or dusty environment.

Use a soft-bristled brush 

When cleaning your teak furniture, choosing the right tools is crucial to protect its delicate surface and enhance its natural grain. Opt for a soft-bristled brush or a soft cloth to tackle dirt and stains.

Avoid using steel wool or abrasive cleaning pads, as they can scratch the wood and damage its surface. A soft brush or cloth will effectively remove dirt and stains without causing any damage.

Avoid using harsh chemicals

Harsh chemicals can strip away the natural oils and colour of teak wood, causing it to become brittle and prone to cracking. Avoid using bleach or ammonia on your teak furniture. Instead, opt for a mild detergent or a natural cleaning solution such as vinegar or baking soda. 

Don't pressure wash your teak furniture

While pressure washing might seem like a quick way to clean outdoor teak furniture, it's too harsh for delicate teak wood.

The intense pressure from the power wash can damage the wood's structure and strip away the protective natural oils, leaving it vulnerable to environmental elements.

Instead, learn how to use a water hose or a bucket of water to rinse away any dirt or debris. If you need to remove stubborn stains or mildew, use a mild cleaning solution and a soft-bristled brush.

Invest in teak protector

To maintain the aesthetic and structural integrity of your teak furniture, investing in a quality teak protector from a trusted furniture shop is crucial.

Teak protectors not only offer an added level of UV protection but also create a barrier that minimises oxidation by preventing extensive air contact with the wood. Ensure the teak is completely dry before applying a thin coat of the protector.

Regular maintenance, including retouching the protective film a couple of times each year, will keep your teak furniture looking great and significantly extend its lifespan.

Targeted stain removal

Even with regular maintenance, teak furniture can encounter stubborn stains that require special attention. Issues like mildew growth and oil spills can penetrate the wood, making it resistant to general cleaning methods.

These specific challenges demand targeted solutions to effectively restore the wood's natural beauty without causing damage. Fortunately, there are proven techniques on how to address these concerns, ensuring your teak furniture remains in pristine condition. 

How do I remove black spots and mildew?

Teak outdoor furniture is susceptible to developing black spots, also known as mildew, especially if it's exposed to damp or humid conditions. Mildew not only detracts from the furniture’s appearance but can also degrade the wood if left untreated, potentially leading to permanent damage.

Removing these unsightly black spots is crucial for maintaining both the aesthetic and structural integrity of your teak furniture.

To remove these stains, start by creating a solution of equal parts water and white vinegar or bleach. Alternatively, you can use a solution of warm water and dish soap. However, if the mildew has been left growing and untreated for a while, you might need a stronger solution like commercial teak cleaners to help you get the job done.

Next, use a soft-bristled brush or a clean cloth to apply the cleaning solution to the affected area. Be sure to wear gloves when working with mildew or harsh chemicals. Gently scrub the area with the brush or cloth, paying particular attention to any dark spots. Be careful not to scrub too hard, as this can damage the wood.

After scrubbing the area, rinse it thoroughly with clean water to remove any remaining cleaning solution or debris. If the mildew is still visible, repeat the cleaning process until the stains are removed.

To prevent mildew from returning, keep your teak furniture clean and dry. Regularly removing moisture and debris can significantly deter mildew growth.

Additionally, consider the placement of your furniture; avoid areas prone to dampness or excessive humidity, which are ideal environments for mildew to thrive. To further protect the wood, apply a teak sealer or use a furniture cover to help protect the wood from moisture and UV rays.

Should I oil my outdoor teak furniture?

Teak wood naturally contains oils that make it resistant to water, rot, and insect damage, which is why it’s highly valued for outdoor furniture. Initially, oiling may not seem necessary due to these natural properties.

However, over time, teak wood can lose its natural oils, especially when exposed to continual sunlight and weather elements. This loss can lead to the wood turning grey or silver if left untreated.

Oiling your teak furniture can help restore its natural colour and protect it from weather damage, fading, and cracking. Teak oil will penetrate the wood, creating a protective layer that repels water and prevents the wood from drying out.

Additionally, teak oil enhances the wood’s natural grain, giving it a refreshed shine and making it appear more vibrant and inviting. Regular oiling can significantly extend the life and beauty of your teak furniture, making it a worthwhile step in your maintenance routine.

How do I remove oil stains?

Oil stains can occur from various sources, such as food spills, body oils, or maintenance products that are not properly wiped off.

These oils can seep into the porous surface of the wood, creating stains that darken over time and are difficult to remove if not addressed promptly. The longer these oils sit on the wood, the deeper they penetrate, making the removal process more challenging. Here’s how you can try and get rid of them. 

Start off by blotting up as much of the oil as possible using a clean cloth or paper towel. Be gentle and avoid rubbing the stain, as this can spread the oil further. Then, mix a cleaning solution using warm water and a mild detergent or teak cleaner. Dip a soft-bristled brush into the solution and gently scrub the stain. After scrubbing the stain, rinse the area thoroughly with clean water to remove any remaining cleaning solution or oil. If the stain is still visible, repeat the cleaning process.

If the stain is particularly stubborn, you may need to sand the affected area with fine-grit sandpaper. Be sure to sand in the direction of the wood grain and avoid using too much pressure, as this can damage the wood. This method can help restore the teak's surface, effectively removing deep-seated stains and preparing it for further teak repair or sealing.

Remember to let your furniture dry completely before reassembling them or covering them with furniture covers.
