One huge threat, and not a pleasant one, is growing moss. If you see signs of this unpleasant greenery, don’t panic! Our guide is here to help you deal with this problem, no matter how persistent it may be! 

What is moss?

Moss forms from spores that are carried by wind currents and moving water. Usually, it can not grow in areas that are occupied by healthy plants, therefore the presence of moss on your garden furniture might be a sign of underlying problems in your soil. While it may not be harmful to your garden, getting rid of it would help you keep your outdoor furniture clean and tidy.

Why do you find it on your garden furniture?

Moss will grow on any hard surface, mostly North-facing surfaces, due to the fact that they need more humid and darker environments. So, you guessed it right, your patio furniture is no exception to this rule.

How to clean moss of garden furniture step-by-step

Before you start cleaning, you should make sure that anything besides the furniture itself such as outdoor cushions is removed and stored inside the house. Let’s get started!

Method 1: Warm soapy water

Mostly effective in the early stages of growing moss, this method requires simple things you probably already have in your household.

List of materials

  • Bucket
  • Dish soap
  • Soft brush
  • Garden hose
  • Cloth


  1. Warm approximately four litres of water (a gallon of water) and pour it into a big bucket.
  2. Put a few drops of dish soap and swirl it with your fingers until the water lathers. You can use rubber gloves if you don’t want your hands getting wet.
  3. Proceed with dipping the brush into the bucket then scrubbing any moss-covered spots on your furniture. Give extra time with stubborn stains: they can be tricky but not impossible to deal with.
  4. Once you’re done scrubbing, attach a garden hose and rinse thoroughly the surfaces you worked on. Wipe off the water using a dry cloth and let the sun do the drying for you!

Method 2: Vinegar

Similar to the previous method with the addition of a powerful ingredient: vinegar!


  1. Fill your bucket with a good balance of white vinegar and warm water
  2. Dip your brush into the mixture and proceed with scrubbing in detail: be careful not to miss any spots, this is your chance! If you see stains from moss on your teak furniture, we would recommend using a sponge instead of a brush in order to avoid leaving marks
  3. When you are done scrubbing, let the chairs and couches absorb the solution for  5-10 minutes. 
  4. Proceed with scraping off the moss and scrubbing. If you can use a kitchen knife for scraping, without harming the furniture (and yourself of course) even better! 
  5. Use your garden hose for rinsing and a soft cloth or a clean towel to wipe off the water. Rinse and repeat the process until you are satisfied with the result!

Method 3: Baking soda

If the previous methods won’t work for you, then don’t be discouraged. Baking soda is your dearest friend in cleaning stubborn stains!


  1. Create a mixture of warm water and baking soda. The amount of baking soda you would use depends on the density and quantity of the moss. Minimum wise you should use one spoon of baking soda to four litres of warm water. For bigger patches of moss, increase the dose of the baking soda
  2. Dip your soft brush into the mixture and rub any moss-covered surfaces vigorously. Don’t rinse yet and let your wood furniture absorb the mix you’ve created for about one day. Don’t forget that you can always use rubber gloves if you don’t want your hands getting wet or smelly.
  3. After the day has passed, check back on your outdoor furniture to see if the moss can be removed using a brush or a clean broom. If yes, then rinse with your garden hose and dry with a clean cloth.

Method 4: Bleach

Let’s face it, no cleaning guide is complete without the bleach solution. This time wearing rubber gloves is a MUST!


  1. Use a bucket to create a mixture of bleach and warm water. The preferable ratio should be about 150 millilitres of bleach to 4 litres of water.
  2.  If you have a garden spray to pour the solution into, it would be ideal, in order to save time and effort. Otherwise using a soft brush and carefully rubbing the surfaces is equally as effective. Just make sure that you dip your brush regularly before rubbing. Before anything else you need to consider moving your wooden garden furniture away from any plants, you might have, as bleach can harm them. Moving your outdoor furniture to the driveway might be a good solution. Proceed by spraying or scrubbing the surfaces.
  3. Let your wood or plastic furniture absorb the bleach mix you’ve created. We would recommend waiting at least 15 minutes before you wash it away with hot water. You might notice the moss turning yellow; this means the moss is dying and using a brush to remove it should be an easy task.
  4. Last but not least, use your garden hose to rinse and a cloth to dry your outdoor furniture

Method 5: Pressure washing 

If you don’t like using any of the above methods or don’t feel like bringing your inner chemist out to play, then you should try the pressure washing method.

Pressure washer can be used on surfaces with extreme moss, mildew and it is extremely effective and fast in dealing with mould growth. For our green case, use a pressure washer to spray moss affected areas of your garden furniture.

Just be careful not to harm any of the furniture while doing so. Plastic furniture usually can withstand water pressure but it always depends on the quality. We would recommend spraying from a proper distance in order to avoid any damages to your chairs or tables. We would also suggest spraying in sweeping motions in order to properly cover all the inconspicuous areas. Whether wooden or plastic furniture you must always dry thoroughly your outdoor units after!

Method 6: Algae Cleaning Products

Will an algae cleaning product work on removing moss from your luxurious outdoor couch? The answer is yes!

Much similar to algae and lichen, removing moss from your garden can be tricky. No worries, because the cleaning solutions don’t end with the DIY methods. Just visit your local shop and you’ll see a wide array of cleaning products that could help you deal with moss. What you need to do is apply the product (usually by spraying) on surfaces affected by moss.

Many of these cleaning products work with specific temperatures and provide better results when it’s not raining, so make sure you will read the instructions and the forecast. Simply spray the outdoor furniture and voila! After two weeks the results should be visible. Remove any remaining grime and rinse thoroughly. It is highly recommended to spray after two or three weeks on surfaces where the moss is thicker. We would also recommend you to prefer environmentally friendly cleaning products.

Tips for after cleaning treatment

Once you are done with the cleaning process always make sure your garden furniture is well dried, as mentioned above. Proceed with spraying disinfectant on all surfaces you’ve cleaned, let it sit for 24 hours and rinse it off properly. If you own wood furniture we recommend using teak oil to provide moisture protection. Owners of teak furniture should skip this tip, as it’s naturally oily. Depending on where you live, dealing with moisture, and therefore growing moss, you should consider using additional methods after cleaning treatment, such as wood wax.

How to prevent it from coming back

As simple as it may seem, it is important to keep your outdoor furniture tidy and clean. Remove any unnecessary debris from your tables and couches on a regular basis. As we mentioned before, moss loves darker places and moisture, so make sure your favourite chair won’t be a host for it. Always make sure, if possible, that your garden furniture is exposed to direct sunlight. Investing in a good garden furniture cover might also be a good idea.
