What to Use to Clean Off Outdoor Deck Furniture

Outdoor deck furniture faces year-round exposure to sun, rain, wind, and debris, which can lead to fading, staining, mold, and buildup over time. Whether your furniture is made of wood, plastic, wicker, metal, or fabric, regular maintenance is essential to keep it looking good and functioning well. One of the most common homeowner questions is: what to use to clean off outdoor deck furniture? From everyday household items to specialized cleaners, the right tools and methods will depend on the furniture’s material and the type of dirt or damage. This guide covers everything you need to know to clean outdoor furniture effectively and safely.

General Cleaning Principles for All Outdoor Furniture

Before diving into material-specific cleaning, it’s important to understand some universal best practices:

• Always test cleaners on a small, hidden area before applying them widely.
• Avoid abrasive brushes or scouring pads that can scratch surfaces.
• Rinse thoroughly after cleaning to remove any soap or cleaner residue.
• Allow furniture to dry completely in the sun to prevent mold and mildew.

No matter the furniture material, consistent cleaning—at least once per season—will extend its lifespan and keep your outdoor space inviting.

Cleaning Plastic and Resin Furniture

Plastic and resin furniture are low-maintenance and durable, but they still accumulate dust, pollen, and grime. To clean them:

Supplies to use:

• Warm water and mild dish soap
• A soft-bristle brush or sponge
• White vinegar for mildew
• Baking soda for stubborn stains

Method: Mix warm water with dish soap in a bucket. Use a sponge or brush to scrub the furniture, focusing on crevices and joints. For mildew, spray with a 1:1 solution of vinegar and water, let it sit for 10 minutes, then scrub and rinse. For scuff marks or discoloration, make a paste of baking soda and water and gently rub the area.

Cleaning Wooden Outdoor Furniture

Wooden furniture, especially if untreated or natural, needs gentle care to prevent damage or discoloration. Teak, cedar, and eucalyptus are common choices for outdoor decks.

Supplies to use:

• Mild dish soap and water
• Soft brush or microfiber cloth
• Teak or wood cleaner (for deeper cleans)
• Sandpaper (for refinishing or smoothing)

Method: Mix mild soap with warm water and use a soft brush to scrub with the grain. Rinse and allow to dry. If your furniture has developed a gray patina or deep-set stains, use a specialized wood or teak cleaner. Sanding may be required to refresh aged or weathered surfaces before applying a sealer or protective oil. We also have a fantastic guide on how to clean teak outdoor furniture.

Cleaning Metal Furniture

Metal furniture, whether wrought iron, aluminum, or steel, is generally resistant to the elements but can develop rust or oxidation if neglected.

Supplies to use:

• Mild soap and water
• White vinegar for rust spots
• Baking soda paste for tougher grime
• Steel wool or sandpaper (for removing rust)
• Protective wax or rust inhibitor spray

Method: Wash with warm soapy water and a soft sponge. For rust spots, apply white vinegar and scrub gently. For deeper rust, use fine steel wool or sandpaper carefully, then rinse and dry. To prevent future rusting, apply a thin coat of car wax or a rust-preventive sealant.

Cleaning Wicker and Rattan Furniture

Wicker and rattan are popular for their vintage aesthetic but can be tricky to clean due to their woven construction.

Supplies to use:

• Soft-bristle brush
• Vacuum with brush attachment
• Mild soapy water
• Soft cloth for drying

Method: Start by vacuuming the surface to remove loose dirt. Mix warm water with mild soap and gently scrub with a brush, working into the weave. Avoid soaking the furniture, especially natural rattan. Rinse with a damp cloth and let it air dry in the sun.

Cleaning Fabric Cushions and Upholstery

Outdoor cushions and upholstered furniture are designed to resist moisture and fading, but they still need care to prevent mildew and stains.

Supplies to use:

• Mild detergent or upholstery cleaner
• Warm water
• Spray bottle
• Soft brush or sponge
• White vinegar (optional)

Method: Check the manufacturer’s care tag. Most cushions have removable covers that can be machine washed. For spot cleaning, mix warm water with a small amount of detergent in a spray bottle. Spray the solution on the fabric and gently scrub. Let the cushions air dry completely in the sun. For mildew, use a diluted vinegar spray followed by thorough rinsing.

To protect cushions, consider using waterproof covers or storing them indoors during inclement weather.

Natural and DIY Cleaning Alternatives

If you prefer eco-friendly or non-toxic cleaning solutions, many household items can get the job done:

• Vinegar and water: Great for cutting grease and killing mildew.
• Baking soda: A gentle abrasive that helps remove stains.
• Lemon juice: Natural bleaching properties can help brighten surfaces.

These DIY solutions are especially useful for families with children or pets who spend time around the furniture.

Pressure Washing: Use with Caution

While pressure washers are tempting for outdoor furniture cleaning, they should be used cautiously. High pressure can damage wood, crack plastic, or remove paint or finish. If using a pressure washer:

• Set it to the lowest pressure.
• Use a wide-angle nozzle.
• Keep the wand at least 18 inches away from the surface.

Use pressure washing primarily on durable surfaces like metal or composite furniture, not soft wood or fabric.

Regular Maintenance Tips

Beyond deep cleaning, small maintenance habits can keep your outdoor furniture in great condition:

• Cover furniture during rain or snow.
• Store cushions indoors during off-seasons.
• Apply sealant or protective coatings annually.
• Brush off debris like leaves or bird droppings promptly.

These steps prevent long-term staining and wear, reducing the need for frequent heavy cleaning.

Conclusion

Knowing what to use to clean off outdoor deck furniture allows you to preserve your investment and enjoy a clean, comfortable space year-round. By choosing the right cleaning methods for your furniture’s material—whether wood, metal, plastic, or fabric—you can extend its life and keep it looking fresh. From DIY solutions like vinegar and baking soda to specialized cleaners, a thoughtful cleaning routine keeps your outdoor living area ready for relaxation, entertaining, and everyday use.
