How to Care for Your Garden Furniture Year-Round
A garden corner sofa is a significant investment. Looked after properly, it will still look and feel as good in year five as it did on the day it arrived. Neglected, even the most weather-resistant set will show its age within a season or two. This guide covers everything you need to know to keep your garden furniture in excellent condition throughout the year — whatever the British weather decides to do.

Spring — preparing your furniture for the season
Spring is the most important maintenance moment of the year for garden furniture. Whatever condition your set is in after winter, the work you do in March or April will determine how it looks for the entire season ahead.
The spring inspection checklist
Before you do anything else, inspect the furniture carefully after its winter storage or under its cover. You are looking for any signs of damage, deterioration or wear that need to be addressed before the set goes back into regular use.
- Check all frame connections and tighten any bolts that have loosened over winter
- Inspect the frame for any signs of rust, corrosion or damage
- Check rattan weave for any splits, loosening or discolouration
- Inspect cushion inners for any signs of mould or damp
- Check adjustable feet are still level and functional
- For wood sets — check for any cracking, splitting or grey weathering that needs treatment
The spring clean
Once you have completed your inspection, give the entire set a thorough clean before putting it back into use. This removes any mould spores, dirt or residue that has accumulated over winter and gives you a fresh start for the season.
For most materials, a solution of warm water and mild washing-up liquid applied with a soft cloth or brush is all you need. Work methodically across the frame, paying particular attention to joints and corners where dirt tends to collect. Rinse thoroughly with clean water and allow to dry completely before replacing cushions.
Practical tip
Never use a pressure washer on garden furniture. The force of the water can damage rattan weave, strip wood treatments and force water into joints where it causes damage from the inside. A soft brush and mild soap solution is always the safer choice.
Summer — keeping it clean during regular use
During the summer months when your garden furniture is in regular use, a little consistent maintenance is far easier than addressing problems at the end of the season. The goal is to prevent the build-up of dirt, pollen, sunscreen and food residue that can stain fabric and degrade finishes over time.
Weekly maintenance during the season
A quick wipe down of the frame with a damp cloth once a week during regular use is enough to keep most garden furniture looking its best. This takes five minutes and prevents the gradual build-up of grime that becomes much harder to remove if left until the end of the season.
If your furniture is used frequently for outdoor dining or entertaining, pay particular attention to the areas around armrests and the surfaces of any tables in the set. These are the areas most likely to accumulate food residue and drink marks that can become harder to remove if left too long.
After rain
British summers are unpredictable, and your garden furniture will regularly get wet even during the season. Most quality garden furniture handles rain without any issue — but there are a few simple habits that will extend its life significantly.
After heavy rain, tilt or shake cushions to remove standing water before replacing them. If cushions have become thoroughly soaked, stand them on their edge to allow water to drain and air to circulate, and allow them to dry completely before using the furniture again. Sitting on wet foam cushions compresses the filling and can cause it to lose its shape over time.
Worth knowing
If you are going away on holiday or know the furniture won't be used for an extended period during summer, covering it or bringing the cushions inside is worthwhile even in the warmer months. Extended exposure to direct sunlight can fade cushion fabric over time, even on UV-resistant materials.
Autumn — end of season preparation
Autumn is when most of the maintenance work happens. The care you take in September and October directly determines the condition your furniture will be in the following spring. Skipping this step is the single most common reason that garden furniture deteriorates faster than it should.
The end of season deep clean
Before you store your furniture for winter, give it a thorough deep clean. This is more comprehensive than the routine summer maintenance — you are removing the accumulated grime of an entire season and preparing the surfaces to withstand winter storage in the best possible condition.
Clean the frame thoroughly with warm water and mild soap, working into all joints, corners and weave patterns. For rattan, a soft brush helps to remove dirt from between the weave fibres. For wood, use a dedicated wood cleaner before applying any treatment. Rinse everything thoroughly and allow to dry completely — ideally on a dry day with good air circulation — before moving on to the next step.
Treatment before storage
Once the frame is clean and completely dry, apply any material-specific treatments before covering or storing the furniture. For wood sets, this means an application of appropriate wood oil or exterior wood treatment. For rattan and aluminium, a thorough dry is usually sufficient — though a light application of a protective spray designed for outdoor furniture can add an extra layer of protection.
- Remove all cushion covers and machine wash them before storing
- Allow cushion inners to dry completely before storing — never store damp cushions
- Store cushions in a dry indoor location — a garage, shed or spare room
- Deep clean the frame and allow to dry completely
- Apply wood oil or protective treatment if applicable
- Cover the frame with a quality waterproof furniture cover
Winter — storage and protection
Winter in the UK is the hardest season for outdoor furniture. Prolonged moisture, frost and temperature fluctuations all take their toll on materials that are not properly protected. The good news is that with the right preparation in autumn, winter storage is largely passive — the furniture looks after itself.
Covering vs storing indoors
If you have the space, moving your garden furniture indoors for winter — into a garage, outbuilding or large shed — is always the best option. Indoor storage removes all weather risk entirely and means the furniture will be in perfect condition when you bring it out in spring.
If indoor storage is not practical, a quality waterproof furniture cover is the next best option. Look for covers that are specifically designed for garden corner sofas — they should fit the shape of the set properly, be made from a breathable waterproof material that prevents condensation building up underneath, and have straps or ties to prevent them blowing off in wind.
During winter — occasional checks
Even with a cover in place, it is worth checking your furniture once or twice during winter — particularly after severe weather. Check that the cover is still securely in place and has not been damaged by wind. Remove any standing water or snow from flat surfaces. If you notice the cover has allowed moisture to get underneath, remove it, allow the furniture to dry on a dry day, and replace it.
Important
Never cover garden furniture while it is still damp. Trapping moisture under a cover creates exactly the conditions that mould and mildew need to develop. Always ensure the furniture is completely dry before covering it for winter storage.
Material-specific care guide
Different materials require slightly different approaches to maintenance. This quick reference guide covers the most important care considerations for each material type.
| Material | Routine cleaning | Annual treatment | Winter storage |
|---|---|---|---|
| PE Rattan | Damp cloth, mild soap | Not required | Cover outdoors or store inside |
| Aluminium | Damp cloth, mild soap | Not required | Cover outdoors or store inside |
| Acacia Wood | Damp cloth, wood cleaner | Wood oil annually | Store inside or cover outdoors |
| Pine Wood | Damp cloth, wood cleaner | Wood oil or preservative | Store inside recommended |
| Douglas Wood | Damp cloth, wood cleaner | Low — develops naturally | Store inside or cover outdoors |
A note on wood treatment
If you have a solid wood garden sofa, the annual wood oil treatment is the single most important maintenance step you can take. Apply it at the end of the season on a dry day when the temperature is above 10°C. Work the oil into the wood with a cloth or brush, following the grain, and allow it to absorb fully before applying a second coat if needed. The wood should feel nourished and protected rather than sticky or wet.
Use a wood oil that is specifically formulated for outdoor use — teak oil works well on acacia, while a Danish oil or exterior wood treatment suits pine and douglas wood.
Caring for cushions year-round
Cushions are the element of a garden sofa set that requires the most consistent attention. They are in direct contact with people, food and drink, and they absorb moisture from rain and dew in a way that the frame does not. Looking after them properly makes a significant difference to both their appearance and their lifespan.
During the season
Bring cushions indoors during prolonged periods of rain, overnight if possible, and whenever the furniture is not in use for an extended period. This is the single most effective thing you can do to extend the life of outdoor cushions. It takes thirty seconds and makes a substantial difference over the course of a season.
If cushions do get wet, allow them to dry completely in a well-ventilated area before replacing them on the furniture. Stand them on their edge rather than laying them flat, which allows water to drain and air to circulate through the filling.
Washing cushion covers
Most quality outdoor cushion covers are machine washable. Remove the covers, zip them closed to protect the zip mechanism, and wash on a cool cycle with a gentle detergent. Avoid tumble drying — heat can shrink or distort the fabric. Air dry instead, ideally outdoors on a dry day, and refit when completely dry.
Wash cushion covers at least twice during the season — once mid-season and once at the end before storage — and before the covers go back into use in spring.
Storing cushions for winter
Before storing cushions for winter, ensure both the covers and the inners are completely dry. Even slight dampness stored in a bag or box over winter will result in mould growth that is difficult to remove. Store cushions in breathable bags or pillowcases rather than plastic bags, which trap moisture. A dry garage, shed or spare room is ideal.
If mould does develop
Mix one part white vinegar with one part water and apply to the affected area with a soft brush. Leave for 30 minutes, then rinse thoroughly and allow to dry completely in the sun. For persistent mould on cushion covers, a specialist outdoor fabric cleaner will be more effective than a standard detergent.
The year-round care calendar — at a glance
- Spring — inspect, deep clean, tighten connections, refit cushions
- Summer — weekly wipe down, dry cushions after rain, bring cushions in overnight
- Autumn — end of season deep clean, apply wood treatment if applicable, wash and store cushions
- Winter — cover with a quality waterproof cover or store indoors, check occasionally after severe weather
Ten minutes of consistent care across the season is worth more than hours of remedial work at the end of it. A garden corner sofa that is properly looked after will still look and feel excellent five or ten years from now — and will give you far more pleasure in the years between.
