How to Clean and Maintain Outdoor Furniture: Material-by-Material Guide

Outdoor furniture takes a beating—sun, rain, salt air, pollen, bird droppings, mildew. But different materials handle abuse differently, and a cleaning method that works for aluminum will wreck wicker. If you maintain furniture properly for its specific material, you'll get years more life and keep it looking sharp. Here's what to do for each common material you'll find in an outdoor kitchen or patio setup.

Aluminum Frame Furniture

Aluminum is lightweight, rust-proof, and low-maintenance, which is why it's popular for outdoor furniture. Most outdoor chairs and loungers use aluminum frames. The frame itself rarely needs cleaning beyond a rinse, but the weave or sling fabric can trap dirt.

Routine cleaning: Hose it down every few weeks with plain water, scrubbing gently with a soft brush if algae or mildew is building up. Use a garden hose on medium pressure—don't blast it with a pressure washer, which can damage the fabric.

Deep cleaning: Mix warm water with a tiny bit of dish soap (a few drops in a bucket). Use a soft brush or cloth to scrub frame and fabric. Rinse thoroughly with clean water and let dry completely before storing.

Corrosion prevention: Aluminum oxidizes over time, especially near salt water, developing a white or gray powdery coating. This doesn't hurt the furniture, but you can remove it with a specialized aluminum cleaner or white vinegar and a soft brush. Dry thoroughly after cleaning.

Seasonal care: Before storing furniture for winter, clean it, let it dry completely, and store it in a covered space if possible. Moisture trapped against aluminum accelerates corrosion.

Teak Wood Furniture

Teak is dense, oily, and naturally resistant to rot and pests, which makes it ideal for outdoor use. However, teak exposed to sun and weather turns gray over time as the protective oils get weathered away. That's cosmetic, not a structural problem, but many people prefer to maintain the warm, honey-colored finish.

Routine cleaning: Rinse teak furniture with water and let it dry. Once a year, scrub it with a soft brush and warm, soapy water to remove algae or mildew. Don't use a pressure washer—it can damage the grain and surface.

Maintaining the golden finish: Apply teak oil every 6 to 12 months to restore color and protect the wood. Clean the furniture first, let it dry completely (at least 24 hours), then apply teak oil with a cloth, working in the direction of the grain. Let the oil soak for 15 to 20 minutes, then wipe away excess. Teak oil is a real product—not just any wood oil will work outdoors.

If your teak has turned gray: This is normal and doesn't mean the wood is damaged. If you want to restore the color, use a teak brightener (a mild bleach product made for this purpose) or teak stain. Clean thoroughly first, apply the brightener, scrub gently, rinse, and let dry. This revives the natural color without damage.

Seasonal care: No special storage needed. Teak handles rain, frost, and temperature swings. Cover cushions (not the wood) in winter if you live somewhere really harsh. If you're storing it, a dry shed is fine, but the wood doesn't suffer from outdoor exposure.

Wicker and Rattan Furniture

Wicker is woven fiber (natural or synthetic) that weaves air pockets and traps moisture and debris. It requires gentle cleaning because water can weaken the fibers or promote rot if it sits in crevices.

Routine cleaning: Brush dirt and leaves out with a soft brush. Use a vacuum with an upholstery brush attachment to get into the weave. This prevents debris from getting damp and moldy.

Deep cleaning: Mix water with a tiny bit of mild soap. Use a soft cloth or sponge—don't immerse wicker in water. Dampen the cloth, wipe the wicker, and immediately dry with a clean towel. Pay special attention to creases and joints where moisture lingers.

Mildew prevention: If you see dark spots or smell mold, it means moisture has settled in the weave. Use a mixture of one part white vinegar to three parts water. Wipe affected areas, then dry immediately with a towel and let the furniture sit in the sun to dry further. Improve air circulation around the furniture to prevent future mold.

Natural wicker care: Natural wicker (real plant fibers) can dry out and crack in hot, arid climates. Apply a very light coat of linseed oil or furniture wax once or twice a year to maintain flexibility. Apply sparingly and buff off excess so it doesn't get sticky.

Synthetic wicker care: Modern all-weather wicker (usually polyethylene or polypropylene fibers) doesn't need oil. It's more resistant to drying and cracking. Clean it the same way as natural wicker but skip the oil unless the manufacturer recommends it.

Storage: Store wicker in a dry place. Extended exposure to moisture in a damp garage or shed can promote mold and rot, even in synthetic wicker.

HDPE (High-Density Polyethylene) Furniture

HDPE is thick plastic used in Adirondack chairs and other molded furniture. It's waterproof, fade-resistant, and requires almost no maintenance. This is the easy option.

Routine cleaning: Rinse with a garden hose and let dry. Once a month, use a soft brush and soapy water to scrub off pollen or algae. Rinse thoroughly and let dry.

Stubborn stains: Mix water and vinegar in a spray bottle and let it sit for a few minutes, then scrub. For tougher grime, a little rubbing alcohol on a cloth works without damaging the plastic. Avoid harsh chemicals and solvents.

Fading: HDPE resists fading better than most outdoor materials, but sun and time will slowly lighten colors. This is cosmetic and doesn't affect function. If you want to minimize fading, cover the furniture when not in use or position it in partial shade.

Seasonal care: No special care needed. HDPE furniture handles cold, rain, and extended storage without damage. You can leave it outside year-round in most climates.

Wrought Iron Furniture

Wrought iron is heavy, durable, and beautiful, but it rusts if not maintained. Rust spreads and weakens the metal, so catching and preventing it is important.

Routine cleaning: Wipe down with a damp cloth monthly. Use a soft brush to scrub away dirt and pollen from crevices. Wrought iron has lots of detail, so debris accumulates—regular cleaning prevents moisture from sitting against the surface and promoting rust.

Rust prevention: Apply a thin coat of clear wax or furniture polish every few months. This creates a barrier between the metal and moisture. Brands like Turtle Wax or car wax work fine. Apply with a cloth, let it set for a few minutes, and buff off excess with a clean cloth.

Rust removal: If small patches of rust appear, use a wire brush or fine steel wool to scrub them away. Once clean, dry the area thoroughly, then apply wax to prevent re-rusting. If rust is severe or the piece is compromised structurally, it's time to replace it.

Painting: If rust is widespread or the original finish is worn, consider painting with high-temperature metal paint (the kind used for grills or car engines). Clean down to bare metal with a wire brush, prime with metal primer, and apply paint in thin coats. This gives wrought iron a fresh finish and protects it for years.

Storage: If you store wrought iron indoors, choose a dry location. Damp basements promote rust even if the furniture looks fine. A dry garage or shed is better.

Cushions and Sunbrella Fabric

Cushions and outdoor fabric take as much abuse as the frame, and improper care ruins them quickly. High-quality cushions use solution-dyed acrylic or Sunbrella fabric, which resists fading and mildew better than regular fabric.

Routine cleaning: Brush off debris with your hand or soft brush. Vacuuming the surface with an upholstery attachment works too. This prevents dirt from embedding into the fibers.

Spot cleaning: For small stains, mix warm water with a tiny bit of mild soap (or Woolite). Dampen a cloth and blot the stain—don't rub aggressively, as this pushes dirt deeper. Rinse with clean water and air dry. For wine, juice, or food stains, blot immediately before they set.

Deep cleaning: Mix two cups of water, one cup of bleach, and a quarter cup of mild soap in a spray bottle. (Use regular bleach, not color-safe.) Spray the entire cushion surface, let it sit for 5 to 10 minutes, scrub gently with a soft brush, rinse thoroughly with clean water, and air dry completely. This works for mildew and stubborn stains. Do this once or twice a year for high-traffic cushions.

Drying: After any wet cleaning, stand cushions upright in a sunny spot with good air circulation. They need to dry completely—water trapped inside promotes mold. Don't store damp cushions.

Sunbrella care: Sunbrella is a premium outdoor fabric brand. It's solution-dyed, so stains don't penetrate as deeply. Clean Sunbrella the same way as regular outdoor fabric: mild soap, water, soft brush, and thorough rinsing. Sunbrella actually handles bleach better than some fabrics (check your fabric tag for sure), so don't hesitate to use the bleach-soap mix above if needed.

Storage: Remove cushions from furniture before winter and store them in a dry place indoors. Moisture and temperature fluctuations break down fabric and foam. Stack them loosely so air can circulate, and cover with a breathable tarp if they'll sit a long time.

Seasonal Maintenance Schedule

Spring (after winter storage):

  • Take furniture out, inspect for damage or rust.
  • Clean all surfaces thoroughly—this is a good time for deep cleaning before heavy use starts.
  • Replace any broken cushions or damaged covers.
  • Oil teak, wax wrought iron, and treat wicker.
  • Test chairs and tables for stability before inviting people to sit on them.

Summer (use season):

  • Brush and vacuum weekly to prevent debris from accumulating.
  • Spot-clean cushions as needed.
  • Rinse aluminum and plastic frames occasionally to wash away salt air or pollen.
  • Watch for mildew growth in damp areas and address it with vinegar solution immediately.

Fall (preparation):

  • Deep clean everything before storing for winter.
  • Remove cushions and store indoors.
  • Apply protective treatments—teak oil, wrought iron wax, furniture sealants.
  • Repair any damage before storing (it's easier to do now).
  • Cover furniture or store it in a shed or garage to protect from harsh weather.

Winter (storage season):

  • Keep furniture dry and protected from snow and ice.
  • Check periodically (every month or so) to make sure no moisture is accumulating underneath.
  • Don't store items on top of furniture that might crush it.
  • Keep mice and insects out of the storage area—they can damage fabric and chew wood.

Frequently Asked Questions

Can I use a pressure washer on outdoor furniture?

Not usually. Pressure washers are too aggressive and can damage fabric, wood grain, and wicker fibers. Use low-pressure garden hose water instead, or wash by hand with a soft brush and soapy water. The only exception is heavy metal frames (wrought iron) where you can use low-pressure settings, but hand cleaning is still safer.

How do I prevent mildew on cushions?

Good air circulation is key. Don't stack damp cushions, and don't leave them in a dark, humid spot. If you're in a humid climate, remove cushions from furniture during winter or cover them with a breathable cloth (not plastic, which traps moisture). Vacuum and brush them regularly so moisture doesn't accumulate in the fibers. If mildew does appear, clean with the bleach-soap solution above.

Is teak oil waterproof?

Teak oil enhances the natural color and protects against UV damage, but it's not truly waterproof. It does help repel water initially, but rain will still wet the wood. Teak is naturally rot-resistant, so the oil is more about aesthetics and protection from drying out. Reapply every 6 to 12 months.

Can I leave cushions outside year-round?

In mild climates, yes. In areas with cold winters, rain, and snow, no. Extended exposure to moisture, temperature swings, and UV damage breaks down foam and fabric. Store cushions indoors during winter to extend their life.

What's the difference between natural and synthetic wicker?

Natural wicker is plant fiber and requires more maintenance—oiling to prevent drying and regular inspection for rot. Synthetic wicker (polyethylene or polypropylene) is plastic and needs only basic cleaning. Both look similar, but synthetic lasts longer with less care. Synthetic is the practical choice for full-time outdoor placement.
