Outdoor Furniture Care: How to Keep It Looking Its Best
Extend the life of garden furniture with the right cleaning, oiling, rust prevention, textile care and winter storage for wood, metal, rattan and plastic.
Outdoor furniture can last a few seasons or well over a decade depending on its material, exposure and maintenance. UV light, moisture, temperature changes and pollen affect every surface differently, so one universal treatment can cause more harm than good.
Cleaning and oiling wooden outdoor furniture
UV light greys timber and moisture repeatedly expands and contracts the fibres. Teak contains natural oils, oak and acacia are dense, while softwoods such as pine absorb water faster and normally need more frequent protection.
- Pine and spruce: inspect and oil annually, preferably before the season.
- Oak and acacia: usually every one to two years.
- Teak: every two to three years, or allow it to develop a natural silver patina.
Do not oil damp wood or apply a thick layer. In direct sun, a pigmented exterior oil generally provides better UV protection than a clear product. Avoid a pressure washer because it can damage the wood fibres; use a soft brush, lukewarm water and mild cleaner.
How to oil wooden furniture
- Clean the surface and let it dry fully for about 24 hours.
- Sand lightly with P180–P240 paper in the grain direction.
- Apply a thin coat of suitable exterior oil.
- Wipe away excess after 15–20 minutes.
- Allow 12–24 hours to dry and apply another thin coat if required.
Work in dry weather around 15–25°C and follow the product instructions. Oil-soaked cloths can self-ignite: after use, submerge them in water or store and dispose of them in a suitable sealed metal container according to local guidance.
Teak and hardwood
Some products sold as teak oil form a surface film. Check the ingredients and finish type before use. Pure tung oil penetrates wood and is more moisture-resistant than linseed oil, but any product must be suitable for exterior furniture. A silver-grey teak patina is an aesthetic change, not necessarily structural damage.
Metal furniture and rust prevention
Aluminium forms a protective oxide layer and does not rust like steel. Wrought iron and steel need an intact protective coating. Clean both with mild detergent and dry joints and welds carefully. Avoid abrasive, chlorine or acidic products on powder-coated aluminium.
For steel, remove loose rust with P120–P240 abrasive, clean the surface, apply anti-corrosion primer and finish with two compatible exterior paint coats. Inspect bolts and joints each spring because trapped moisture often starts corrosion there.
Rattan and plastic furniture care
Natural rattan absorbs moisture and belongs under a roof. Synthetic PE rattan tolerates outdoor conditions better. Clean synthetic weave with a soft brush, mild soapy water and a small brush for gaps, then dry the frame thoroughly. Vacuum natural rattan first and wipe it only lightly with a damp cloth.
Clean plastic with mild detergent. A baking-soda paste can help with stubborn marks, while chlorine bleach can damage polymers. UV protectant may slow fading, but cracked or brittle plastic has aged structurally and should be assessed for safe replacement.
Outdoor cushions and fabrics
Wash removable covers according to the label, commonly at 30°C with mild detergent. Air-dry in shade; high dryer heat can shrink fibres and distort seams. Treat stains promptly and test any cleaner on a hidden area.
Renew water repellency with a compatible fabric protector when needed. Keep cushions dry overnight where possible and store them in a dry ventilated place during winter.
Preparing garden furniture for winter
Aluminium and synthetic PE rattan can often remain outside under a breathable, well-fitted cover. Wood, steel and natural rattan last longer in a dry ventilated shed, garage or covered area. Always clean and dry furniture completely before covering it.
Tighten bolts, inspect hinges and protect moving joints as recommended by the manufacturer. A durable polyester or 600D Oxford cover should have ventilation openings and secure straps. It should cover the furniture without lying directly on the ground; a small lower air gap helps moisture escape.
Frequently asked questions
How often should outdoor furniture be maintained?
Clean it at the start of the season and once or twice during summer, with extra pollen removal as needed. Inspect cushions every few weeks and wood at least annually.
Should furniture stay outside in winter?
Aluminium and synthetic rattan may remain under a ventilated cover, but wood, steel, natural rattan, cushions and fabrics benefit from dry indoor storage.
What is best for wooden furniture?
Use an exterior wood oil or protective finish specified for the timber and exposure. A tinted UV-protective product is often preferable on a sunny open terrace.
How is rust removed from steel furniture?
Remove corrosion to sound metal, clean and dry the area, apply compatible anti-corrosion primer and repaint. This process is for steel and iron, not aluminium.
