How to Care for & Store Garden Furniture

A good garden set should last a decade, not a single summer — but the British climate is unforgiving, and left to the elements even premium furniture greys, splits and rusts within a couple of seasons. The difference between furniture that looks tired by August and furniture that still charms guests five years on comes down to a handful of simple routines: cleaning correctly, covering intelligently and storing over winter. This guide walks you through caring for every common material, season by season, with real methods, dilutions and timings you can actually follow.

1. Know your material first

Every care decision starts with what your furniture is made of, because the routine that protects teak will strip the finish off aluminium, and the brush that suits rattan will scratch glass. Before you buy a single product or fill a bucket, identify each material in your set — a typical garden dining set might combine a powder-coated steel frame, a tempered-glass top and polyester cushions, each with different needs.

The main outdoor materials fall into a few families. Hardwoods such as teak, acacia and eucalyptus are naturally oily and rot-resistant but weather to silver-grey unless oiled. Metals split into powder-coated aluminium (rustproof, low-maintenance), powder-coated or wrought steel (strong but prone to rust where the coating chips) and cast iron (heavy, classic, needs rust management). Synthetic rattan — technically PE or HDPE resin woven over an aluminium frame — is the workhorse of modern garden sofas and chairs and shrugs off rain, though its frame and cushions still need attention. Natural rattan and wicker, by contrast, are strictly for covered or indoor use and will disintegrate if rained on.

If you are unsure what you own, check the product listing or a magnet: a magnet sticks to steel and iron but not to aluminium. Knowing this one fact tells you whether rust is even possible, which shapes your entire care plan.

2. The seasonal care calendar

Garden furniture care is not a single annual chore — it is four light touches spread across the year, which together take far less effort than one heroic scrub in spring. Think of it as bookending the season: prepare in spring, maintain lightly through summer, deep-clean and pack away in autumn, and check on it midwinter.

• Spring (March–April): uncover, deep clean, re-oil timber, check metal frames for rust spots, and inspect cushions after storage. This is your big set-up job of the year.
• Summer (May–August): a quick wipe every two to three weeks and a rinse after pollen-heavy or dusty spells. Bring cushions in overnight if rain threatens.
• Autumn (September–October): the most important job of all. Deep clean everything while it is still mild enough to dry outdoors, then oil, cover or store before the first frosts.
• Winter (November–February): if furniture stays out under covers, check every three to four weeks that covers haven’t shifted and that no water is pooling on top.

Get the autumn job right and spring becomes a pleasure rather than a rescue mission. Furniture that goes into winter clean and dry, with cushions stored indoors, emerges ready to use with barely a wipe.

3. Cleaning without wrecking the finish

The golden rule of cleaning outdoor furniture is to start as gently as possible and only escalate if needed. Most people reach straight for a pressure washer, which forces water into timber grain, blasts protective coatings off metal and shreds rattan weave. For the vast majority of jobs, warm water and a mild solution do everything a jet wash does, without the damage.

Here is the safe method by material:

• Teak and hardwoods: use warm water with a squirt of washing-up liquid and a soft brush, working along the grain. Rinse and let it dry fully. For stubborn grey or algae, a dedicated teak cleaner lifts it without sanding.
• Aluminium and powder-coated metal: warm soapy water and a soft cloth. Avoid abrasive pads or acidic cleaners, which dull the powder coat. Dry with a microfibre cloth to prevent water spots.
• Synthetic rattan: soapy water and a soft brush to reach into the weave, then rinse with a hose on a gentle setting. A soft toothbrush handles tight corners where grime collects.
• Glass tops: standard glass cleaner or a vinegar-and-water mix, buffed dry to a streak-free finish. Check the frame’s fixings while you are there.

Whatever the material, always let furniture dry completely before covering or oiling. Trapping moisture is the single most common cause of mould, mildew and rust — a surface that feels dry to the touch may still hold water in joints, so give it a warm, breezy day to finish.

4. Caring for cushions and fabrics

Cushions are almost always the first part of a set to look tired, because fabric holds moisture, feeds mildew and fades in UV light faster than any frame. The good news is they are also the easiest element to protect: keep them dry and out of prolonged sun and they will outlast the trends.

Most quality outdoor cushions use solution-dyed acrylic or polyester covers with a quick-dry foam or fibre core. Spot-clean spills immediately with a damp cloth and a little mild detergent. For a deeper clean, check the care label — many covers unzip and are machine-washable at 30°C, but always air-dry rather than tumble-dry, which can shrink the cover and warp the foam. Never put damp cushions back onto furniture or into storage; mildew can take hold within 48 hours.

The best habit of all is simply not leaving cushions out in the rain. Bring them indoors overnight, or store them in a waterproof cushion box or a dry corner of the shed between uses. If you love the layered look, indoor-outdoor rugs and a few weatherproof cushions can be swapped out easily and stored together at the end of the season.

5. Covering the right way

A good cover is the cheapest insurance you can buy for garden furniture, but a badly fitted or badly chosen cover does more harm than no cover at all. The problem is trapped moisture: a cheap, non-breathable tarpaulin sealed tight to the ground creates a warm, humid pocket where condensation, mould and rust thrive.

Choose covers that are breathable and waterproof — look for a woven polyester with a PU or PVC coating and, ideally, mesh vents that let air circulate while shedding rain. Fit matters: a cover should be snug enough not to flap and let rain in, but not so tight it seals moisture against the furniture. Most quality covers have drawcords, click clips or elasticated hems to hold them firm in wind.

• Make sure furniture is bone-dry before covering — never cover something you have just cleaned.
• Leave a small gap at the base for airflow rather than sealing the cover to the ground.
• Add a raised object such as a small pot or a purpose-made cover support under the centre of a table so water runs off instead of pooling.
• Check covers after every storm; a shifted cover exposing one corner defeats the whole purpose.

6. Winter storage, step by step

Wherever you have the space, storing furniture indoors over winter — in a shed, garage, summerhouse or dry outbuilding — beats leaving it out under covers every time. Even the best cover cannot match four dry, frost-free months under a roof. Where indoor storage isn’t possible, the covering method above will see most weatherproof furniture through, but follow this sequence either way.

1. Clean everything first. Store furniture dirty and you are locking dirt, sap and moisture against the surface for months. Deep clean and let it dry completely.
2. Treat as needed. Oil hardwoods, touch up any chipped metal coating, and check rattan weave for loose strands before they worsen.
3. Bring cushions and fabrics indoors. These should never overwinter outside, even under a cover. Store them dry, on edge, somewhere ventilated.
4. Fold, stack or dismantle. Folding chairs and stackable pieces save huge amounts of space. Loosen and store any removable bolts in a labelled bag taped to the frame.
5. Raise off the floor. Stand metal and timber on blocks or pallets so they aren’t sitting on cold concrete that wicks up moisture.
6. Cover loosely indoors. A breathable dust sheet keeps grime off without trapping damp.

If your set lives on a balcony or in a flat with no storage at all, prioritise bringing in the cushions and use a well-vented cover for the frame — that alone prevents most winter damage.

7. Protecting, oiling and sealing

Protective treatment is what turns three years of life into ten, and it is mostly about wood and metal. Timber and rust are the two things that quietly deteriorate when you aren’t looking, so a little proactive care pays off enormously.

For hardwoods, you have a choice. Left untreated, teak and acacia weather to an elegant silver-grey — this is purely cosmetic and doesn’t harm the wood, so if you like the driftwood look, simply clean it annually and leave it. If you prefer the original warm honey tone, apply teak oil or a specialist hardwood oil once or twice a year: clean and dry the wood first, apply a thin, even coat with a brush or lint-free cloth along the grain, leave it to soak in for 20–30 minutes, then wipe off any excess. Do this in spring and again in early autumn for furniture in heavy use.

For metal, the enemy is rust starting where the coating has chipped. Inspect frames each spring and autumn. At the first sign of a rust spot on steel or iron, sand it back lightly with fine wet-and-dry paper, wipe clean, and touch up with a matching enamel or a rust-inhibiting primer and paint. Catching a pinhead of rust early stops it spreading under the coating, where it can eventually bubble a whole panel. Aluminium never rusts, which is why it dominates low-maintenance ranges, but its powder coat still benefits from a wipe of car wax once a year to keep water beading off.

8. Fixing common problems

Even well-cared-for furniture throws up the occasional issue. Most are quick to fix if you catch them early, and the table below covers the ones we’re asked about most, matched to the material they typically affect.

The thread running through all of these is the same: small, regular attention beats occasional heroics. Five minutes tightening bolts and spotting a rust fleck in April saves a ruined frame in October. And when a set has genuinely reached the end of its life — weave perished, frame corroded through — it is worth refreshing rather than nursing. Browse the current ranges in garden furniture to see how much more weather-resistant modern all-aluminium and HDPE sets have become.
