How to Clean Outdoor Furniture: A Material-by-Material Guide

Outdoor furniture lives a hard life. One day it’s baking under harsh sunlight, the next it’s covered in rain, pollen, or sticky humidity. Slowly, colors fade, surfaces dull, and dirt settles deep into the material . But here’s the good news: with the right approach, you can keep your furniture looking fresh for years. No expensive treatments or complicated tools required. This guide walks you through exactly how to clean each type of outdoor furniture, step by step.

Why Cleaning Regularly Matters

A quick wipe now and then helps, but that’s only surface cleaning. Over time, wood starts to crack, metal begins to rust, and colors fade without warning . Regular cleaning prevents these problems before they start—removing hidden grime, stopping mold patches, and protecting your investment .

Lightly clean every 2–3 weeks during heavy use, with a deeper cleaning at least once every season .

Before You Start: The Universal Cleaning Solution

You likely already have everything you need in your kitchen. Mix warm water with a few drops of dish soap, and you have a versatile cleaner that works on most outdoor furniture surfaces . For tougher buildup, add a splash of white vinegar to the mix .

Essential tools:

• Soft-bristle brush

• Microfiber cloths

• Garden hose with spray nozzle

• Bucket

• Vacuum with brush attachment

Important: Always test any cleaner on a small, hidden area first .

How to Clean Different Materials

Wooden Furniture (Teak, Acacia, Eucalyptus)

Wood looks beautiful but requires gentle care. Here’s the right way to clean it:

1. Remove loose debris with a soft brush.

2. Mix mild soap with warm water and scrub lightly in the direction of the wood grain .

3. Rinse with clean water using a hose (avoid pressure washers—they can splinter or crack wood surfaces ).

4. Let it dry completely before applying any protective coating.

5. Apply teak oil or wood sealer to bring back the natural shine and protect from sun and rain .

For mildew stains: Dissolve 1/2 cup of powdered oxygen bleach (not chlorine bleach!) in 1 gallon of hot water. Apply to affected areas, let sit for at least 15 minutes, scrub, rinse, and dry .

Restoring weathered wood: If your wooden furniture is weather-worn, use a stiff wire brush to scrub away splintered wood or cracked paint. Use a putty knife to apply wood filler for major cracks, sand smooth once dry, then prime and paint following the wood grain .

Metal Furniture (Aluminum, Wrought Iron, Steel)

Metal is strong and durable, but rust can creep in quietly. Here’s how to protect it:

1. Wipe down with warm, soapy water and a microfiber cloth .

2. Rinse thoroughly and dry immediately with a towel—letting water sit on metal surfaces leads to water spots and rust .

3. For rust spots on iron or steel: Saturate a cloth with distilled white vinegar, place it on the rusty area, and let sit for about 30 minutes. Scrub gently with a soft-bristled brush, rinse, and dry completely .

4. Apply protective wax or sealant to prevent future rusting .

For aluminum: Clean powder-coated and uncoated aluminum with soapy water, rinse well, and dry to prevent spotting. To keep the finish shiny, coat the metal with paste car wax and buff .

Plastic and Resin Furniture

This is the easiest material to clean. Here’s how:

1. Mix 1 cup of white vinegar with 2 liters of warm water and scrub with a sponge or soft brush .

2. Rinse thoroughly and leave to dry in the shade .

3. For tough stains: Create a paste of baking soda and water, apply to stains, scrub lightly, and rinse .

Protect from sun damage: Apply a thin coat of automotive paste wax to plastic furniture after cleaning to keep it looking good longer. The wax helps stains and dirt slide right off .

Wicker and Rattan Furniture

Wicker’s woven texture traps dust and debris in hard-to-reach spots. Here’s how to clean it carefully:

1. Vacuum thoroughly using a brush attachment or crevice tool to remove loose dirt from the weave .

2. Mix warm water with mild detergent and gently wipe with a cloth or soft brush .

3. Use a toothbrush for tight spots and crevices .

4. Rinse gently with a damp cloth—avoid soaking the material .

5. Let it air dry in a shaded spot to prevent cracking or fading from direct sunlight .

Pro tip: If the coating on your wicker is deteriorating, re-seal it with a paste wax to maintain water resistance .

Outdoor Fabric Cushions and Upholstery

Cushions take the most damage from sun, rain, and spills. Here’s how to keep them fresh:

Spot Cleaning:

1. Mix warm water with mild soap and dab stains with a cloth.

2. For tougher stains, apply a paste of baking soda and water, let sit for 15 minutes, then scrub and rinse .

3. Avoid harsh chemicals—they break down fabric coatings .

Deep Cleaning Cushions:

1. Check care labels first—many covers can be machine-washed on a gentle cycle .

2. If covers aren’t removable, vacuum loose dust, then scrub with soapy water and a soft brush .

3. Rinse thoroughly using a garden hose with a spray nozzle.

4. Air dry completely in the sun before replacing—damp cushions invite mildew .

For mildew stains on removable covers: Pretreat mold and mildew spots with distilled white vinegar and baking soda (up to 30 minutes). Wash, then air-dry to prevent shrinkage . For non-removable covers, mix 1 cup bleach, ¼ cup mild detergent, and 1 gallon water in a spray bottle. Spray on, wait 15 minutes, scrub with a soft-bristled brush, and rinse .
