Hey there! If you have Black Spots on Outdoor Furniture, don’t worry, you’re not alone. 

Exposure to the elements can cause these unsightly marks to appear, but the good news is that they can be easily removed. 

In this guide, we’ll walk you through some simple steps to help you get rid of those pesky black spots and restore the beauty of your outdoor furniture.

Understanding the Causes of Black Spots:

Black spots on outdoor furniture can be caused by various factors. Let’s take a closer look at each one:

Mold and Mildew:

If your furniture is located in a damp or humid environment, mold and mildew can develop. 

These fungal growths thrive in moist conditions and can leave behind black or greenish spots.


Certain metals, such as iron or aluminium, can oxidize when exposed to air and moisture. This oxidation can create black spots or patches on the surface of your furniture.

Tannin Stains:

If your outdoor furniture is made of wood, leaves or other organic matter can release tannins, which can cause black stains. These stains are particularly common on wooden surfaces.

Identifying the cause of the black spots will help you choose the most effective method to remove them.

Cleaning with Soap and Water:

Start by giving your outdoor furniture a thorough cleaning using mild dish soap and warm water. 

Fill a bucket with water and add a few drops of dish soap, then use a sponge or soft brush to scrub the affected areas gently. 

Pay extra attention to the black spots, making sure to cover them thoroughly. 

Rinse off the soap with clean water and allow the furniture to dry completely before moving on to the next step.

Using Vinegar Solution:

If soap and water didn’t do the trick, try using a vinegar solution. Vinegar is a natural cleaner with excellent antimicrobial properties. 

Mix equal parts of white vinegar and water in a spray bottle. Spray the solution onto the black spots and let it sit for about 15 minutes. 

Then, scrub the spots with a sponge or brush, and rinse with clean water. Vinegar can effectively remove black spots, mold and mildew stains, leaving your outdoor furniture looking fresh and clean.

Applying a Bleach Solution:

For tougher stains, a bleach solution can be used. However, it’s essential to exercise caution and follow safety guidelines when working with bleach. 

Before using bleach, make sure your furniture is suitable for it. Some materials, like fabric or certain types of wood, may be sensitive to bleach and can be damaged. 

Mix one part bleach with three parts water and apply it to the black spots using a sponge or cloth. 

Let it sit for a few minutes, then scrub gently and rinse thoroughly with water. 

Be sure to test the bleach solution on a small, inconspicuous area of the furniture first to ensure it doesn’t cause discoloration.

Utilizing Baking Soda Paste:

Baking soda is a versatile and safe cleaning agent that can be used to remove black spots from outdoor furniture. 

Create a paste by mixing baking soda with a small amount of water until it forms a thick consistency. 

Apply the paste to the black spots and let it sit for 15-20 minutes. Scrub the spots gently with a sponge or brush, then rinse off the paste with water. 

Baking soda’s mild abrasive nature helps lift stains and eliminate odors, leaving your furniture looking revitalized.

Prevention is Key:

To keep your outdoor furniture looking great, prevention is crucial. Here are some tips to help you prevent the formation of black spots on outdoor furniture:

Regular Cleaning: 

Establish a routine for cleaning your outdoor furniture. 

After rainy or humid periods, make sure to give your furniture a thorough cleaning to remove any moisture or debris that may contribute to the growth of mold, mildew, or stains.

Weather Protection:

Consider using furniture covers to shield your outdoor furniture from the elements when not in use. 

Covers can help prevent moisture buildup and reduce the chances of mold or mildew growth.

Proper Drainage:

Ensure that your outdoor furniture has adequate drainage to prevent water from pooling and causing prolonged moisture exposure. 

Check that water can freely flow off the surfaces and away from the furniture.

Regular Inspection:

Regularly inspect your outdoor furniture for any signs of damage and black spots, such as cracks or loose joints. 

Promptly repair or replace any damaged parts to prevent water infiltration, which can lead to the formation of black spots.

Leaf and Debris Removal:

Leaves, twigs, and other organic matter can release tannins, which may cause black stains on wooden furniture. 

Remove any fallen leaves or debris from your furniture regularly to minimize the risk of staining.

Proper Storage:

If possible, store your outdoor furniture indoors during extreme weather conditions, such as heavy rain or winter. This will provide extra protection and prolong the lifespan of your furniture.
