How to Clean Wicker Furniture: The Complete Guide

First, Identify What Your Wicker Is Made From

"Wicker" describes a weaving technique — not a single material. Furniture labeled as wicker could be natural rattan, bamboo, willow, paper fiber, or synthetic polyethylene rated for outdoor use. The distinction determines everything about how you clean it.

Cleaning methods safe for synthetic outdoor wicker can permanently damage natural wicker. Water that rinses harmlessly off polyethylene will warp rattan, crack bamboo, and feed mold inside paper-fiber weave. Start with identification.

Not sure which you have? Check the product label, care guide, or the furniture underside. Synthetic wicker looks uniform, with consistent strand thickness, and is typically woven over an aluminum or metal frame. Natural fibers show more texture variation and irregularity — that's the giveaway.

Color doesn't tell you much. White wicker could be painted natural or white synthetic resin. Each needs different care.

Outer outdoor wicker is a synthetic polyethylene weave engineered for uncovered outdoor use. The full washing and rinsing instructions that follow are written for synthetic all-weather wicker — including Outer All-Weather Wicker. Read more about how it's made.

What You Need — and What to Avoid

Most routine outdoor wicker cleaning requires only mild soap, water, and soft tools. Aggressive products create damage harder to fix than the original dirt.

Use

• Vacuum with brush attachment or soft handheld brush
• Bucket of lukewarm water
• Mild dish soap or mild laundry soap (~2 oz per gallon of water)
• Soft-bristle cleaning brush
• Soft toothbrush for narrow gaps in the weave
• Microfiber cloth or soft towel
• Garden hose with adjustable nozzle (gentle to medium setting)
• Shaded, well-ventilated drying spot

Avoid

• Pressure washers and high-pressure hose settings
• Bleach on Outer wicker frames
• Abrasive powders, scouring cleaners, or stiff scraping tools
• Steel wool or metal brushes
• Strong solvents or undiluted chemicals
• Very hot water
• Covering or replacing cushions while the frame is still damp
• Natural-wicker oils or polish applied to synthetic wicker

How to Clean Outdoor Wicker Furniture in Seven Steps

Work on the frame and cushions separately. Start dry, use the mildest effective method, and let everything dry fully before reassembly. Rushing the drying step is where most damage starts.

Step 1: Remove Cushions and Accessories

Take off all cushions, pillows, blankets, and anything else sitting on or near the furniture. Check beneath cushions and around the frame for leaves, insects, pollen, and trapped debris. If cushions need more than spot cleaning, follow the cushion cleaning guide separately.

Step 2: Remove Loose Dirt Before Adding Water

Use a vacuum brush attachment, soft brush, or dry microfiber cloth. Work top-down — including the underside, corners, connection points, and where wicker meets the internal frame. Dry debris turns to mud when wet, and mud works its way deeper into the weave than dry dust ever does.

Step 3: Rinse Synthetic Wicker Lightly

Use a garden hose on gentle or medium setting. Keep the nozzle far enough away to produce an even, broad spray — not a concentrated jet. This loosens surface-level dirt and prevents you from scrubbing grit into the strands in the next step. Skip this step for natural, painted, antique, or unidentified wicker.

Step 4: Mix A Mild Cleaning Solution

Add roughly 2 oz of mild soap to 1 gallon of lukewarm water. More soap doesn't clean better — it leaves residue that attracts dirt faster. For Outer All-Weather Wicker, a standard mild dish soap or mild laundry soap works. No specialty products required.

Step 5: Clean Along The Weave

Dip a soft-bristle brush into the solution and gently clean from top to bottom. Alternate between horizontal and vertical strokes to follow the weave pattern — don't scrub against it. Use a soft toothbrush for narrow spaces where strands overlap, around connection points, and in corners. Change the water when it becomes visibly dirty. Dirty water re-deposits the grime you just removed.

Step 6: Rinse Thoroughly

Rinse top-down using gentle or medium hose pressure until no soap remains. Check the underside and corners — these are where water and soap residue collect and where mold starts if left unchecked.

Step 7: Towel Off and Air-Dry Completely

Remove excess water with a clean towel, then let the frame air-dry in partial shade or filtered sunlight. Direct midday sun on a wet frame can cause uneven drying and water spotting. Do not replace cushions or install a full cover while the frame is damp — trapped moisture breeds mildew inside 48 hours.

How Often Should You Clean Wicker Furniture?

Brush or vacuum loose debris as needed. Wipe spills immediately. Deep-clean at least once per outdoor season. The schedule depends on exposure, not the calendar — a patio in full sun near the coast needs attention more often than a screened-porch piece in a mild inland climate.

Routine maintenance: Brush away debris, wipe spills, and light-clean during heavy-use periods. A quick brush takes two minutes. Letting pollen, food residue, or bird droppings sit for months turns a simple maintenance task into a restoration project.

Deep-clean triggers: Start or end of an outdoor season. Before extended storage or covering. After storms, parties, nearby construction, heavy pollen, or noticeable salt exposure. If the furniture looks dull even when dry, it's overdue.

For cleaning frequency guidance specific to cushions, see the complete Care & Maintenance guide.

How to Handle Common Stains and Outdoor Buildup

Different debris types need slightly different approaches. Start with the mildest method, don't scrape the weave, and check manufacturer guidance before stronger treatments.

Mold and Mildew

Visible mildew usually signals trapped moisture somewhere. Move the furniture to a well-ventilated area, brush away dry debris, and clean with the mild-soap solution. Rinse and let every section dry before replacing cushions or covers. For Outer wicker, avoid bleach and abrasive cleaners. If mildew persists after normal cleaning, contact Outer before using anything stronger.

White Wicker

Don't assume white wicker needs bleach. Identify the material first. Synthetic white wicker cleans with the same mild soap and water as other colors — no special treatment required. For painted or older white wicker, test any cleaner in a hidden area. The wrong product can lift the finish or cause yellowing that's impossible to reverse.

How Climate Changes Wicker Care

Outdoor wicker faces different threats depending on where you live. Strong sunlight, frequent rain, high humidity, salt air, and freezing weather each create distinct cleaning priorities.

Intense UV and Heat

Hot, sunny patios accumulate fine dust, sunscreen, body oils, and baked-on pollen faster than shaded spaces. Clean oily marks promptly — heat bonds them to the weave. Brush dust regularly. Dry freshly washed wicker in partial shade, not midday sun. During extended non-use, use architectural shade or a full furniture cover. Synthetic wicker resists UV better than natural fibers, but no material is immune to years of direct exposure.

Frequent Rain and Snow

After heavy rain, check beneath cushions, around furniture feet, and inside low points in the frame where water pools. Let everything dry before covering. Before winter: remove debris, deep-clean the frame, dry it fully, and use a fitted, ventilated cover or protected storage. Never use sharp tools to remove ice from wicker — you'll cut the strands.

High Humidity

Inspect the underside of cushions, the back of the furniture, and where wicker meets the internal frame — these shaded zones stay damp longer than visible surfaces. Never cover wet furniture. During extended humid periods, lighter but more frequent cleaning prevents organic debris from feeding mildew. A dry brush every week in humid climates does more for longevity than a deep-clean twice a year.

Coastal Salt Air

Salt spray creates a fine, abrasive film on wicker, legs, hardware, and connection points. Rinse the frame after noticeable salt exposure, coastal storms, or strong onshore wind. Follow with mild soap if the film remains. Inspect metal components during the same routine — even corrosion-resistant materials benefit from regular salt removal. Salt doesn't just sit on the surface; it grinds into the weave with every breeze.

Seasonal Transitions

Season changes are the natural moment to inspect the weave, remove accumulated debris, deep-clean, and decide what level of protection makes sense for the months ahead.

Spring: Remove covers. Inspect frame and weave. Clear winter debris. Deep-clean before first use.

Summer: Respond quickly to food, sunscreen, pollen, and high-use messes. Protect cushions between uses with OuterShell®. Rinse more often if you're near the coast.

Fall: Remove leaves from the weave and beneath furniture before they trap moisture and decompose against the frame. Clean and dry before temperatures drop.

Winter: Clean and fully dry the frame. Install a fitted All-Weather Cover or move to protected storage. Brush snow off covers after each accumulation — sitting snow compresses and eventually leaks through. Read the winter storage guide.

Three Layers of Protection for Easier Outdoor Living

The most effective strategy isn't cleaning more often — it's reducing how much dirt and moisture reach the furniture. Outer uses three distinct protection layers. Each handles a different part of the piece and a different level of exposure.

Layer 01 · Frame — All-Weather Wicker

A synthetic polyethylene weave, handwoven over a durable internal aluminum structure and designed for uncovered outdoor use. "All-weather" means it handles rain, sun, and temperature swings far better than natural wicker. It doesn't mean zero maintenance — but it means less.

Layer 02 · Cushions — OuterShell®

Outer's patented built-in cover protects the seating surface from dirt, debris, pollen, and morning dew. It's sewn into the cushion — deploy it by pulling the integrated handle forward and seating the rod. Fifteen seconds per seat. No storage bag, no straps, nothing to lose. OuterShell® protects cushions, not the wicker frame. It reduces routine cushion care but doesn't replace frame cleaning.

Layer 03 · Full Piece — All-Weather Cover

A fitted cover protects the entire furniture piece — wicker frame included. This is the additional layer for frequent rain, snow, wind, salt air, storms, and extended periods of non-use. Only install after the furniture is clean and completely dry. Putting a cover over damp wicker accelerates mildew.

The Long-Term Cost of Wicker Furniture

Purchase price is one number. Ownership cost is another. Soap and brushes are cheap. The real expense is time — moving cushions, cleaning surfaces, waiting for things to dry, reacting to unexpected weather, and repeating the process year after year.

Five-year ownership cost = purchase price + protection + cleaning supplies + cleaning time + repairs + replacement. A lower sticker price doesn't always mean a lower total if the furniture demands constant cushion storage, intensive cleaning, early repairs, or full replacement after limited outdoor exposure.

Ask before buying: Is the wicker rated for outdoor exposure? Are the cushions washable? Is everyday protection built in or sold separately? Can a fitted full cover be added later? What do the warranty terms actually cover? Read the full wicker buying guide.
