How to Clean and Maintain Garden Furniture: A Simple Guide

To be honest—British weather doesn’t do our garden furniture any favours. One minute it’s sunny, the next it’s raining sideways. Over time, all that moisture, dirt, and fluctuating temperatures can leave your once-beautiful outdoor setup looking tired and grubby.

That’s why giving your garden furniture a good clean isn’t just about keeping it looking nice, but about making it last. Whether it's rattan, plastic, or even cushioned seats, each material has its own quirks. This guide keeps things simple and practical, with easy-to-follow tips and material-specific advice that’ll have your furniture looking fresh and ready for sunshine in no time.

Step 1: Know Your Garden Furniture Type First

Before you get the sponge and soap out, it’s important to understand exactly what kind of furniture you’re dealing with. Why? Because using the wrong cleaning method can do more harm than good—scratching, fading, or even weakening the material.

Here’s a quick overview of the most common garden furniture types you'll find:

Wood – Includes hardwoods like teak and eucalyptus, and softwoods like pine. Natural-looking, but needs regular care to avoid rot and weathering.
Metal – Think wrought iron or aluminium. Strong and sturdy, but can rust or discolour without the right protection.
Rattan/Wicker – Especially popular in synthetic form. Stylish and lightweight, but the weave can trap dirt and algae.
Plastic – Budget-friendly and low-maintenance, but prone to staining and fading over time.
Fabric Cushions & Upholstery – Found on garden sofas and chairs. Comfortable, yes—but a magnet for mildew, pollen, and grime.

Understanding the material is the first step toward cleaning it the right way—and avoiding those costly mistakes.

Step 2: Cleaning by Material: What Works Best

Different materials need different TLC. Whether it’s a solid teak bench or a plastic patio set, here's how to clean each type without fuss—and keep it looking great all season.

2.1 Wooden Garden Furniture

Hardwoods like teak and eucalyptus are built to last, but they still need care to stay looking their best. Use a soft brush and a mild soapy solution to scrub away dirt and mildew. For a deeper clean, you can use a specialist teak cleaner—but avoid harsh chemicals that strip away natural oils.

Softwoods like pine are more vulnerable to moisture. Clean gently using warm soapy water and a soft sponge, and make sure it’s fully dry before using or covering it. Consider applying a wood preservative to protect against the elements.

Top tips to prevent rot and warping:

Keep wooden furniture off soggy grass or soil—use patio slabs or decking if possible.
Cover it during heavy rain (but only when it’s dry!).
Re-oil or seal wood annually to maintain its water resistance.

2.2 Metal Garden Furniture

Got rust? No panic. Use a wire brush or fine sandpaper to gently remove rust spots, then wipe clean with a damp cloth. For tougher patches, try white vinegar or a rust remover product.

To prevent corrosion, dry the furniture completely after cleaning and apply a metal-friendly protective wax or spray (especially on wrought iron). For aluminium, a light coat of car wax works wonders.

Cleaning without damaging the finish:

Avoid abrasive pads or harsh chemicals that can scratch or dull painted or powder-coated finishes.
Use a mix of warm water and washing-up liquid, then rinse thoroughly and dry with a cloth.

2.3 Rattan and Wicker Furniture

Dirt in the weave? Use a vacuum with a brush attachment or a soft toothbrush to lift out trapped dust and debris. Then, mix warm water with a splash of dish soap and gently wipe it down with a cloth or soft brush.

Pro tip: Avoid pressure washers! They can split natural fibres or damage synthetic ones, ruining the structure.

To protect from UV and fading:

Place furniture in shaded areas or use a UV-protective cover.
For synthetic rattan, an occasional application of a plastic protector spray can help maintain flexibility and colour.

2.4 Plastic Garden Furniture

Faded or stained plastic can look worse than it really is. Use warm water and a splash of white vinegar or baking soda to cut through grime and brighten up the surface. A sponge or cloth is usually all you need.

Brittle plastic in cold weather? It happens. To avoid cracking:

Don’t leave it out in frosty conditions.
Store in a shed or use weatherproof covers through winter.

Tip: Avoid bleach-based cleaners as they can make white plastic yellow over time.

2.5 Outdoor Fabric Cushions

Machine-washable cushions are a breeze—just check the label. Use a gentle cycle with mild detergent, and air dry thoroughly before putting them back out.

Spot-treat stains like mould or grease using a mix of warm water, vinegar, and a drop of dish soap. Dab, don’t rub. For mildew, sprinkle baking soda over the area, spray with vinegar, and scrub gently.

Smart storage = longer life:

Store cushions in a dry, breathable storage box or indoors when not in use.
Avoid leaving them out overnight or during rainy spells, even if they’re “weather-resistant.”

3. Seasonal Garden Furniture Care

UK weather can be a bit of a wild card, so looking after your garden furniture with the seasons in mind is key to keeping it in top shape.

3.1 Spring Checklist

When spring rolls around and the sun finally decides to show up, it’s the perfect time to:

Inspect for damage: Check for cracks, mould, rust, or any loose joints after winter storage.
Give everything a clean: Use the right method for each material (see Section 2 above), and make sure furniture is completely dry afterwards.
Re-oil or seal wood: Especially hardwoods—this helps protect against rain and moisture.
Touch up metalwork: If you notice chips in the paint or small rust patches, fix them early before they get worse.
Freshen up cushions: Wash or spot-clean outdoor fabric, and let everything air dry thoroughly in the spring breeze.

3.2 Autumn & Winter Prep

Before the frost kicks in, a bit of prep will save you a lot of hassle come spring.

Clean before storing: Don’t leave furniture dirty—it invites mould, mildew, and corrosion.
Dry thoroughly: Moisture left in cushions or furniture can lead to rot or rust during storage.
Use breathable covers: Waterproof garden furniture covers are great, but make sure they allow air circulation to avoid condensation build-up.
Store cushions indoors: Even weatherproof ones last longer when stored in a dry, ventilated area.
Lift furniture off wet ground: Use risers or place on dry decking to avoid sitting in water for months.

5. Safety First: Tips to Clean Smart

A clean garden is great—but staying safe while you do it is even better. Here’s how to clean your furniture the smart way:

5.1 Wear Protective Gear

Whether you’re using natural cleaners or commercial ones, it’s always wise to:

Wear rubber gloves to protect your skin.
Pop on eye protection if spraying strong solutions.
Keep pets and little ones away until everything’s rinsed and dried.

5.2 Test Cleaning Agents First

Before going full steam ahead:

Always spot test any cleaner on a hidden section first especially on wood, fabric, or painted finishes.
This helps avoid any unexpected discolouration or damage.

5.3 Dispose of Waste Properly

Eco-friendly mixtures can often go down the drain with plenty of water.
Chemical cleaners may need special disposal. Check the label or your local council’s guidelines.
Avoid dumping dirty water near plants or lawns if it contains bleach or strong detergents.
