Teak has a reputation for being virtually indestructible. And for good reason - it's the timber of choice for outdoor furniture that genuinely needs to last. But "low maintenance" isn't the same as "no maintenance," and in Ireland's wet, variable climate, a little care goes a long way.
The good news is that teak is one of the most forgiving materials you can have in your garden. This guide covers everything you need to know to keep it looking its best - whether that means a warm golden finish or the classic silver-grey that comes with time.
Why Teak Lasts So Long
Teak (Tectona grandis) is a dense tropical hardwood with an unusually high natural oil content. That oil is what sets it apart. It makes the timber naturally water-resistant, prevents warping and cracking as the wood expands and contracts, repels insects and fungi, and gives it a weight and density that most other outdoor timbers can't match.
When you invest in teak, you're investing in something that will outlast the garden it sits in - provided you give it the occasional bit of attention.
The Silver-Grey Question
Before anything else, it's worth addressing the most common question people have about teak: why is it turning grey?
This is completely normal. Left outdoors without treatment, teak naturally weathers over time to a silver-grey colour. The natural oils migrate from the surface as the wood is exposed to UV light, rain, and oxygen. What's left behind is an oxidised patina that many people find extremely attractive - it gives the furniture a driftwood-like quality that suits relaxed, natural garden styles beautifully.
The silver-grey finish is not damage. The wood is still just as strong, still just as water-resistant, and will continue performing exactly as it should.
So before you start treating your furniture, decide which look you want:
- Warm golden-honey tones — requires regular cleaning and oiling, roughly once a year
- Silver-grey patina — requires cleaning only, no oiling needed
Neither is the wrong choice. It comes down to personal preference.
Cleaning Your Teak Furniture
Regardless of whether you oil your furniture or leave it to silver, cleaning once or twice a year is recommended. In Ireland particularly, the combination of damp winters and mild temperatures creates good conditions for green algae and mould to develop on outdoor surfaces - teak included.
What You'll Need
- A soft-bristle brush or sponge
- Warm water and mild washing-up liquid, or a dedicated teak cleaner
- A garden hose or bucket of clean water for rinsing
How to Clean
- Remove any loose debris - leaves, dirt, bird droppings - with a dry brush first.
- Mix a small amount of washing-up liquid with warm water (or use a teak cleaner as directed on the packaging).
- Scrub the surface with your brush or sponge, working along the grain of the wood. Don't scrub across the grain, as this can raise the fibres.
- Rinse thoroughly with clean water and allow to dry completely before applying any oil.
One session is usually enough to lift any green algae or surface grime. For more stubborn staining, a dedicated teak cleaner will do a better job than dish soap - it's worth keeping a bottle on hand.
What to Avoid
Pressure washers. It's tempting, but a pressure washer can damage the surface of teak, driving water deep into the grain and raising the fibres. A hand brush and soapy water is much kinder to the wood.
Bleach or harsh chemicals. These strip the natural oils from the timber and can cause long-term damage to the surface. Stick to mild detergents or purpose-made teak cleaners.
Should You Oil Your Teak Furniture?
If you want to maintain the warm golden colour and keep the oils present in the surface layer, oiling once a year is the way to do it. Spring is the best time - clean first, let the wood dry fully, then apply the oil.
Choosing a Teak Oil
Use a product specifically labelled as teak oil or teak furniture oil, available for purchase here. These are typically linseed or tung oil-based, blended for penetration into dense hardwoods. Avoid general-purpose wood oils and Danish oil, which aren't formulated to penetrate teak's natural oil content effectively.
How to Apply Teak Oil
- Make sure the wood is completely clean and dry. Applying oil to damp wood traps moisture inside, which can lead to discolouration or mould.
- Apply the oil generously with a clean cloth, brush, or lint-free pad, working along the grain.
- Leave it to soak in for 15–20 minutes.
- Wipe off any excess that hasn't been absorbed - pooled oil on the surface will go sticky.
- Allow 24 hours to dry before use.
One or two coats per year is sufficient. Over-oiling can lead to a build-up on the surface that looks uneven or sticky, so less is more.
Dealing with Stains
Teak handles outdoor life well, but occasional stains from food, drink, or plant pots are inevitable.
Water rings and light stains can usually be removed with a light sand along the grain using 120-grit sandpaper, followed by a clean and re-oil if needed.
Rust marks from metal feet or fixings can be lifted with a small amount of oxalic acid cleaner (available in hardware shops), applied carefully and rinsed thoroughly.
Oil or grease stains from barbecues or garden machinery should be treated quickly with a dish soap and warm water scrub before they penetrate the grain.
Winter Care in Ireland
One of teak's genuine advantages in an Irish garden is that it doesn't need to be stored indoors over winter. Its natural density and oil content mean it handles cold, wet conditions without warping or cracking the way softer timbers would.
That said, a little preparation in autumn will keep it in better condition:
- Give it a clean before the worst of the weather sets in. This removes any organic matter that would encourage algae growth over the winter.
- Check for moisture traps. If your furniture sits on legs, make sure water can drain freely and isn't pooling on or around the wood.
- Consider a breathable furniture cover for the wettest months. This isn't essential, but it will keep the surface cleaner and reduce the frequency of your spring clean. Avoid non-breathable plastic covers, which trap condensation and can cause mould.
If you do have storage space and prefer to bring your furniture indoors for winter, store it somewhere dry and well-ventilated. Don't wrap it in non-breathable plastic sheeting.
A Simple Annual Routine
If you want a practical schedule to follow, here's what we'd recommend for most Irish gardens:
Spring (March–April)
- Clean thoroughly with soapy water and a brush
- Allow to dry for 48 hours
- Apply teak oil if you want to maintain the golden colour
- Check fixings and tighten any loose screws
Summer (as needed)
- Wipe down after use to remove food and drink spills
- A quick brush to remove debris
Autumn (October)
- Clean before winter
- Apply a second coat of oil if desired
- Consider a cover for the winter months
That's genuinely it. Three or four hours of work per year will keep teak furniture looking excellent for decades.
