Keeping your wood outdoor furniture clean ensures its longevity and maintains its natural beauty. Exposure to the elements can cause dirt buildup, discoloration, and even damage if left unattended. Regular cleaning and proper maintenance can help protect your furniture, allowing you to enjoy it for years to come. This guide will provide you with simple and effective steps for how to clean wood outdoor furniture and keep it looking its best.

The Impact of Outdoor Elements
Wood outdoor furniture is constantly exposed to a variety of outdoor elements, such as sunlight, rain, wind, and humidity. Over time, these factors can take a toll on the furniture, leading to issues like fading, warping, mold growth, and cracking. Prolonged exposure to UV rays from the sun can bleach the wood, dulling its natural color and weakening its structure.
Similarly, moisture from rain or high humidity levels can seep into the wood, causing it to swell or rot if not properly sealed. Wind can carry dirt and debris that can scratch or abrade the surface, adding to the wear and tear. Understanding the impact of these elements is crucial to developing a routine maintenance plan that will help preserve the furniture’s quality and durability.
Gathering Your Cleaning Supplies
Before you begin cleaning your wood outdoor furniture, it’s essential to gather the right supplies to ensure a thorough and safe cleaning process. You will need a soft-bristle brush or sponge to avoid scratching the surface, a bucket filled with warm water, and a mild dish soap or wood-friendly cleaner.
For tougher stains or mold, white vinegar or a specialized wood cleaning solution can be used. Additionally, have a microfiber cloth or towel on hand for drying the furniture after cleaning, as leaving it wet can encourage mold growth. If your furniture has intricate details or hard-to-reach areas, a small soft brush, like an old toothbrush, can be helpful. Ensuring you have the proper supplies will make the cleaning process more efficient and effective while protecting the integrity of the wood.
10 Methods How to Clean Wood Outdoor Furniture
1. Use Mild Soap and Water for Routine Cleaning
One of the easiest and safest ways to clean wood outdoor furniture is by using mild soap and water. Mix a few drops of dish soap with warm water in a bucket. Dip a soft cloth or sponge into the solution and wipe down the furniture, making sure to remove dirt, dust, and light stains. Rinse thoroughly with clean water and allow it to air dry completely before use.
2. Apply White Vinegar Solution to Remove Mold and Mildew

Mold and mildew can develop on wood furniture due to moisture exposure. A natural and effective way to remove them is by using a white vinegar solution. Mix equal parts of white vinegar and water in a spray bottle, and spray it generously onto the affected areas. Allow the solution to sit for about 10–15 minutes, then scrub gently with a soft-bristle brush. Rinse with water and dry the furniture in a well-ventilated area.
3. Use Baking Soda for Stubborn Stains
For tougher stains, baking soda acts as a natural and gentle abrasive. Create a paste by mixing baking soda with a small amount of water. Apply the paste to the stain and gently scrub with a soft brush or sponge. After scrubbing, wipe the area with a damp cloth and rinse with water. This method helps lift stains without damaging the wood’s finish.
4. Clean with Oxygen Bleach for Deep Cleaning
Oxygen bleach is a safer alternative to chlorine bleach and effectively removes deep-seated dirt, stains, and mold. Mix oxygen bleach with warm water according to the product’s instructions. Apply the solution to the furniture using a sponge or soft cloth, scrubbing lightly as needed. Let it sit for 10–15 minutes before rinsing thoroughly with water. Allow the furniture to dry completely before use.
5. Use a Pressure Washer Cautiously for Quick Cleaning
A pressure washer can be a fast way to clean heavily soiled wood outdoor furniture. However, it should be used with caution to avoid damaging the wood. Use a low-pressure setting (under 1200 PSI) and hold the nozzle at least 12 inches away from the surface. Move the spray in a sweeping motion to prevent concentrated pressure on one spot. After washing, allow the furniture to dry completely in the sun.
6. Apply Lemon and Salt for Natural Disinfection
Lemon and salt work together as a natural disinfectant and stain remover. Cut a lemon in half and sprinkle coarse salt over the cut surface. Use the lemon to scrub the wood, focusing on areas with stains or mildew. The acidity of the lemon helps break down grime, while the salt acts as a mild abrasive. Rinse with water and let the furniture dry completely.

7. Use Teak Cleaner for Teak Wood Furniture
Teak wood furniture requires specialized care due to its natural oils. A teak cleaner is designed to remove dirt, stains, and weathered gray layers without stripping the wood’s natural protective oils. Apply the cleaner according to the instructions, scrubbing gently with a soft brush. Rinse with clean water and allow it to dry before applying teak oil or sealant.
8. Sand Lightly to Remove Surface Dirt and Old Finish
If the wood furniture has accumulated stubborn dirt or old finish layers, light sanding can help restore its appearance. Use fine-grit sandpaper (120–150 grit) to gently sand the surface, following the direction of the wood grain. This method removes built-up dirt, stains, and any rough patches. Wipe away the dust with a damp cloth before applying a protective finish.
9. Apply a Protective Sealant to Prevent Future Dirt Build-up
After cleaning, applying a protective sealant helps prevent dirt accumulation and extends the life of the furniture. Choose a wood sealant or outdoor furniture oil suitable for your specific wood type. Use a brush or cloth to apply a thin, even layer, allowing it to soak in before wiping off any excess. Reapply as needed to maintain protection.
10. Store or Cover Furniture When Not in Use
Prevention is key to keeping wood outdoor furniture clean. When not in use, cover the furniture with waterproof covers to protect it from rain, dust, and sun exposure. During colder months or heavy storms, consider storing the furniture indoors or in a covered area to reduce weather-related damage.

Things to Consider When Cleaning Wood Outdoor Furniture
When cleaning wood outdoor furniture, it is essential to take certain factors into account to ensure effective cleaning while preserving the integrity of the wood. First, always identify the type of wood your furniture is made from, as materials like teak, cedar, or pine may require different cleaning methods or products. Using the wrong cleaner can strip away natural oils or harm protective finishes.
Additionally, weather conditions should be considered; cleaning on a dry, sunny day helps ensure the furniture dries thoroughly, reducing the risk of mold growth. It’s also vital to test any cleaning solution on a small, inconspicuous area before applying it to the entire surface. This prevents potential damage or discoloration. Lastly, always follow up with a protective treatment, such as sealing or oiling, to ensure the furniture remains durable and resistant to future wear and tear.
Maintenance and Upkeep
Proper maintenance and regular upkeep are crucial to preserving the beauty and functionality of wood outdoor furniture. Begin by scheduling routine cleanings, even when the furniture does not appear visibly dirty. Regular dusting and wiping down with a damp cloth can prevent dirt and debris from accumulating, which can cause long-term damage to the wood. Inspect the furniture periodically for any signs of wear, such as cracks, splinters, or peeling finishes, and address these issues promptly to avoid further deterioration.
Reapply protective sealants or oils as needed, usually once or twice a year, depending on the type of wood and the environmental conditions. This layer of protection helps repel water, prevent stains, and reduce the effects of sun exposure. Additionally, ensure screws and joints are tightened regularly to maintain structural integrity, as loosened parts can cause wobbling or instability.
If your furniture is exposed to harsh weather or extreme temperatures, it’s best to store it in a sheltered area or use durable covers specifically designed for outdoor furniture. These precautionary measures shield the furniture from rain, UV rays, and freezing conditions, prolonging its lifespan. With consistent care and attention, your wood outdoor furniture can remain a beautiful and functional addition to your outdoor space for many years.
