How to Remove Sap From Deck Wood

Sap is a natural substance that comes from trees and plants. It serves as a vital nutrient for these organisms but can be quite a nuisance when it gets onto other surfaces, such as your deck wood. Not only does sap create an unpleasant sticky feeling on the surface of your deck, but it can also attract dirt and debris, making your deck look unsightly. If left untreated, the sap can even damage your deck wood by discoloring and weakening it over time.

How to Remove Sap From Deck Wood

Fortunately, removing sap from your deck wood is a relatively simple process that can be done using household items and some elbow grease. In this guide, we will discuss the different methods for how to remove sap from deck wood and provide some tips on preventing sap from accumulating on your deck in the future. So, put on your gloves, and let’s get started!

Understanding Sap and Its Effects

Before we discuss methods for removing sap, it’s essential to understand what sap is and how it affects deck wood. Sap is a sticky, viscous substance that flows through trees’ vascular systems, carrying water and vital nutrients throughout the plant. When sap comes into contact with air, it hardens and becomes tacky.

When sap falls onto your deck wood, it creates a sticky mess and can also discolor and weaken the wood over time. The longer the sap remains on the surface of your deck, the harder it will be to remove and the more damage it may cause. Therefore, it’s vital to address any sap spills or drips on your deck as soon as possible.

11 Best Methods on How to Remove Sap From Deck Wood

1. Ice Cubes or Cold Packs:

One of the easiest and most effective methods for removing sap from your deck wood is using ice cubes or a cold pack. Place an ice cube or cold pack on top of the sap, allowing it to harden and become brittle. Once frozen, use a plastic scraper to gently scrape off the hardened sap. Be careful not to scratch or damage the wood while scraping. This method is ideal for smaller sap stains or drips.

2. Rubbing Alcohol:

Rubbing alcohol can be an effective solvent for removing sap from deck wood. Moisten a cloth with rubbing alcohol and gently rub it onto the sap stain until the sap begins to dissolve. Then, use a plastic scraper or a soft-bristled brush to remove any remaining residue. Be sure to test a small, inconspicuous area of your deck first to ensure that the alcohol doesn’t damage the wood. Using a diluted solution of rubbing alcohol and water can also be effective.

3. Denatured Alcohol:

Similar to rubbing alcohol, denatured alcohol can dissolve sap from deck wood. However, it is stronger and more potent than rubbing alcohol, making it more effective for tougher sap stains. Apply the denatured alcohol to a cloth or sponge and gently rub it onto the sap stain. Let it sit for a few minutes before removing the dissolved sap with a plastic scraper or soft-bristled brush.

4. Mineral Spirits:

Mineral spirits, also known as paint thinner, can be an effective solvent for removing sap from deck wood. Apply mineral spirits onto a cloth and gently rub onto the sap stain until it begins to dissolve. Then, use a plastic scraper or soft-bristled brush to remove any remaining residue. Be sure to wear gloves and work in a well-ventilated area when using mineral spirits.

5. Goo Gone:

Goo Gone is a commercial cleaning product specifically designed to remove sticky substances like sap from various surfaces. Apply goo to the sap stain and let it sit for a few minutes before wiping it off with a cloth or paper towel. Repeat as necessary until the sap is completely removed. If using goo gone, be sure to follow the manufacturer’s instructions and test a small area of your deck first to avoid any potential damage.

6. Hand Sanitizer:

Believe it or not, hand sanitizer can also effectively remove sap from deck wood. Apply a small amount of hand sanitizer onto the sap stain and let it sit for a few minutes before wiping it off with a cloth or paper towel. Repeat as necessary until the sap is completely removed. This method is ideal for smaller sap stains or drips. If using hand sanitizer, be sure to test a small, inconspicuous area of your deck first.

7. Vegetable Oil:

Vegetable oil is another household item that can help remove sap from deck wood. Apply a small amount of vegetable oil onto the sap stain and let it sit for a few minutes before wiping it off with a cloth or paper towel. The oil will help dissolve the sap, making it easier to remove. Be sure to clean off any remaining residue with a mild detergent and water solution. This method may require a few repetitions to completely remove the sap.

8. Pressure Washer:

If you have access to a pressure washer, it can be an effective tool for removing sap from deck wood. Use a low-pressure setting and aim the water at the sap stain at a downward angle. This will help loosen and wash away the sap without damaging the wood. Be sure to test a small, inconspicuous area of your deck first and avoid using high pressure, which can damage the wood.

9. Hot Water:

For smaller sap stains or drips, simply pouring hot water directly onto the sap can be an effective method for removal. The hot water will help dissolve the sap, making it easier to wipe away with a cloth or paper towel. Be sure to wear gloves and be careful when handling hot water. Using boiling water can also be effective but should be used with caution to avoid any potential burns.

10. Using Sandpaper:

For tougher sap stains, sandpaper can gently buff away the hardened sap. Use fine-grit sandpaper and lightly sand the surface of the wood until the sap is removed. Be careful not to sand too vigorously or use coarse grits, which can damage the wood. This method may require refinishing the sanded area afterward to restore its appearance.

Lightly Sand the Surface of the Wood

11. Commercial Cleaners:

Various commercial cleaners are available specifically designed for removing sap from deck wood. These products can be purchased at your local hardware or home improvement store. Follow the manufacturer’s instructions and test a small area of your deck before using these cleaners to avoid any potential damage. This method may also require refinishing the cleaned area afterward.

Following these methods can help effectively remove sap from your deck wood without causing any damage. It’s important to address sap stains as soon as possible to prevent them from becoming more difficult to remove and potentially causing damage. Regularly cleaning and maintaining your deck can also help prevent sap buildup in the future.  So, make sure to follow these tips and enjoy a beautiful, sap-free deck all year round.

Additional Tips and Tricks to Remove Sap From Deck Wood

2. Another method to remove fresh sap is to use rubbing alcohol. Soak a cotton ball or cloth in rubbing alcohol and gently rub it over the sap until it dissolves.

3. For tougher, hardened sap stains, you can try using mineral spirits or turpentine. Rub a small amount onto a clean cloth over the affected area. Be sure to test this method on a small, inconspicuous area first to ensure that it does not damage the wood.

4. A pressure washer can also remove sap stains from deck wood. Use a low-pressure setting and hold the nozzle at least 6 inches away from the surface to avoid damaging the wood.

Pressure Washer Can Also Remove Sap Stains

5. Another tip is to use baking soda or cornstarch to absorb the sap. Sprinkle one of these powders onto the affected area and let it sit for a few hours before wiping it off with a damp cloth.

6. If all else fails, you can use a commercial sap remover designed for removing sap from wood surfaces. Be sure to follow the product’s instructions carefully and test it on a small area before applying it to the entire stain.

7. To prevent sap from sticking to your deck in the future, consider using a sealant or stain that repels moisture and prevents sap from penetrating the wood surface.

8. Regularly sweeping or cleaning your deck can also help prevent sap stains from forming as it removes any debris that may contain sap.

9. If trees or plants near your deck tend to produce a lot of sap, consider trimming them back or relocating them to prevent future sap stains.
