Outdoor furniture makes our spaces inviting, but tree sap can create a sticky mess. This gooey substance from trees can stick to furniture, causing stains and potential damage. To keep your outdoor furniture in good condition, you must know how to remove tree sap properly.

We will cover the best ways to get tree sap off your outdoor furniture, whether metal, wood, plastic, or rattan. You'll learn simple techniques to remove sap and get tips to prevent it from returning.

Following the steps in this guide, you can easily clean your outdoor furniture and keep it looking great. With a little effort, you can enjoy your outdoor spaces without worrying about sticky sap ruining your furniture.

What is Tree Sap?

Tree sap is a sticky fluid that trees use to transport water, sugars, and nutrients. It's essential for a tree's growth and healing, but it can be a nuisance when it drips onto outdoor furniture. This natural resin can cause stains and damage if not properly managed.

Many common trees, such as Pine, Maple, Box Elder, Silver Birch, and Sycamore, produce sap. These species are found in various outdoor settings, increasing the likelihood of sap affecting outdoor furniture.

Causes of Sap on Outdoor Furniture

Location of Furniture

The primary cause of sap on outdoor furniture is its placement. If your furniture is positioned under trees, especially those known to produce sap, it’s more likely to get sticky.

Trees provide natural shade, making them popular spots for outdoor setups. However, this also increases the risk of sap dripping onto furniture. The closer your furniture is to overhanging branches, the higher the chance of sap stains and residue.

Types of Outdoor Furniture Affected

Sap doesn't discriminate—it can affect all types of outdoor furniture. Metal furniture may get stained or experience surface damage if the remaining sap is left to harden. Wooden furniture can absorb sap, leading to discolouration and weakening of the wood.

Plastic and rattan furniture can become sticky, making it uncomfortable to use. Even outdoor fabrics, like cushions and parasols, are susceptible to sap stains, potentially leading to damage if not cleaned quickly.

General Methods for Removing Tree Sap

Warm Soapy Water

Warm, soapy water is often the best starting point for removing tree sap. Soak a microfiber cloth in warm water mixed with a small amount of car shampoo or dish soap. Place the cloth on the sap stain and let it sit for a few minutes to soften it.

Once the sap is softened, use the same cloth to wipe it away. This gentle method is suitable for fresh sap stains on various surfaces.

White Vinegar

White vinegar is a natural sap remover. Fill a spray bottle with vinegar thoroughly over the sap spots. Allow it to sit for 5-10 minutes, giving it time to work. After the wait, use a microfiber cloth to wipe away the sap.

This method is effective on various surfaces but may need multiple applications for stubborn sap.

Rubbing Alcohol

Rubbing alcohol can be useful for tougher sap stains, especially on metal patio furniture. Apply it to the sap stain carefully, avoiding painted surfaces, as rubbing alcohol can damage the paint. Dab it on a clean cloth and gently rub the sap until it loosens.

This method is ideal for areas where sap is more stubborn.

Using Cooking Oil

Like vegetable oil, cooking oil can help loosen sap on fabric cushions. Apply a small amount of oil to the sap and let it sit for a few minutes. Then, wash the area with dish soap to remove the oil and the sap. This method is particularly useful for fabric materials that need extra care.

Using Baking Soda Paste

Baking soda paste is great for tougher sap stains. Mix baking soda with warm water to create a paste. Apply it to the sap and let it fizz for a few minutes. Once it has loosened the sap, rinse the area with warm water.

This method can be used on various surfaces but should be applied gently to avoid abrasion.

WD-40 for Tough Sap

WD-40 is a powerful solution for hardening sap on metal surfaces. Spray it directly on the sap and let it work for a few minutes. Afterwards, wipe it away with a clean cloth.

This approach is particularly useful for metal patio furniture with baked-on sap that requires extra strength to remove (1).

How To Remove Sap from Different Materials

How to Remove Sap from Metal Outdoor Furniture

Warm, soapy water is perfect for removing fresh sap from metal furniture. Soak a microfiber cloth in warm water with car shampoo or dish soap, then wipe the sap away. For tougher stains, try isopropyl alcohol, but be careful not to dull the paintwork.

Car tar and sap removers can be useful if the sap is baked on. Follow the product instructions to avoid damaging the metal.

Removing Sap from Wooden Outdoor Furniture

Start with warm, soapy water or WD-40 to remove sap from wooden furniture. If sap persists, use Murphy's Oil Soap undiluted. Let it sit for 10-15 minutes, then scrub with a soft-bristle brush.

A plastic razor blade can be used for hardened sap, but apply with caution to avoid scratching the wood.

Sap Removal for Plastic and Rattan Outdoor Furniture

Warm, soapy water or WD-40 works well for plastic and rattan furniture. Apply gently to avoid damage. If the sap is stubborn, use hand sanitiser with 70% isopropyl alcohol, but test on a small area first to ensure it doesn't dull the finish.

If additional removal power is needed, de.Solv. It is a sticky stuff remover that can be used but avoid overuse.

Cleaning Sap from Garden Parasols and Outdoor Fabrics

To remove sap from garden parasols and outdoor fabrics, soften the sap with warm, soapy water or hand sanitiser with 70% isopropyl alcohol.

A white vinegar solution (40% vinegar, 60% water) can also help, with the bonus of removing mildew or mould stains. After removing the sap, wash it with laundry detergent, rinse it with cold water, and let it dry in the sun for a fresh finish.

Prevention Tips to Avoid Sap on Outdoor Furniture

Placement of Furniture

Choosing the right location is the simplest way to avoid sap on outdoor furniture. Avoid placing your furniture directly under trees that produce a lot of sap, such as Pine, Maple, Box Elder, Silver Birch, or Sycamore.

Reposition your outdoor setup to reduce the risk of sap falling on your furniture.

Regular Cleaning

Regular cleaning is key to preventing sap from becoming a problem. If you notice sap on your outdoor furniture, clean it promptly. The longer sap sits, the harder it becomes to remove. A quick wipe with warm, soapy water can prevent the sap from hardening, saving you time and effort later.

Protective Covers

Using protective covers when your outdoor furniture isn't in use is a great way to shield it from sap. These covers act as a barrier, protecting your furniture from sap, bird droppings, and other environmental factors that could cause damage.

This simple step can significantly prolong the lifespan of your outdoor furniture.

Maintenance

Proper maintenance keeps outdoor furniture in top condition and helps prevent sap-related damage. To create a barrier against sap and other substances, apply protective finishes, such as car wax or weather-resistant coatings.

This maintenance step not only repels sap but also enhances the durability and longevity of your outdoor furniture.
