MaintenanceMaintaining a wooden worktop
A wooden worktop is the only kitchen surface you can repair instead of replace. That advantage only exists if you oil it regularly.
- Oil more often in the first months
- Extra around the sink
- Stains can be sanded out

Oil is not a finish but maintenance
An oiled top has no film on it but oil in the fibre. That oil wears away, so you top it up.
That is its great advantage. A lacquered top with a scratch or burn mark has to be sanded right back and relacquered; an oiled top you sand locally and re-oil, without a visible transition. For a surface that is cut on, spilled on and put down on every day, that is the decisive property.
The rhythm is more intensive at first than later. A new top soaks up a lot in the first months: expect to oil weekly in the first month, then monthly for the first six months, and after that two to four times a year depending on how intensively you cook.
The area around the sink needs separate attention. That is where water stands most often, and exactly where the oil wears away fastest. If you treat the whole top on one rhythm, that area is the first to go dark.
The simplest test: put a few drops of water on the top. If they stay as beads, there is still enough oil in it. If they soak in straight away and the spot darkens, it is time to top up — at least in that spot.

- oil weekly
- First six months

- Around the sink
- more often than the rest
- Testing
- a drop of water — does it still bead?
- Stains
- sand lightly and re-oil
- Never
- hot pans directly on the top
To be fair: a wooden worktop is never finished. It needs attention that a composite or granite top doesn't, and if you let the maintenance slip, within a year you will see dark areas around the sink and stains that have soaked in. It is a material for people who accept the maintenance as part of the kitchen — not for those who never want to give it another thought.

How to re-oil the top
- Clear and clean — damp cloth and mild soap
- Let it dry completely — a few hours
- Sand lightly — grit 180–240, with the grain
- Remove the dust — vacuum, wipe slightly damp
- Apply the oil thinly — more oil is not more protection
- Wipe off after a quarter of an hour — what stays on becomes sticky
- Let it cure — use it as little as possible on the first day
Careful: a bundle of rags soaked in wood oil can spontaneously catch fire as it dries. Lay used rags out flat on a non-flammable surface, or soak them in water before you throw them away.
Stain or wood oil? →How to re-oil the top
- Clear and cleanTake everything off, and wipe the top with a damp cloth and a mild soap. Grease residue stops the oil soaking in.
- Let it dry completelyA few hours is enough indoors. Oil on a damp top won't soak in and stays sticky.
- Sand lightly where neededGrit 180 to 240 on rough patches and on stains. Always with the grain, and over a larger area than the stain itself.
- Remove the dustVacuum and wipe with a slightly damp cloth; let it dry briefly.
- Apply the oil thinlyWith a cloth or a brush, in the direction of the grain. More oil doesn't mean more protection — it simply stays on the surface.
- Let it soak in and wipe offAfter a quarter of an hour, wipe off the excess oil with a clean cloth. Whatever is left becomes sticky and attracts dust.
- CuringUse the top as little as possible on the first day. Full curing takes longer than it feels.

What to do about stains
| Stain | Cause | Approach |
|---|---|---|
| Dark water ring | standing water, oil worn away | sand and re-oil |
| Grease stain | oil or grease soaked in | wipe up straight away; sand out a stain that has soaked in |
| Red wine or beetroot | colour in the fibre | wipe up quickly; otherwise sand it out |
| Black dots | moisture plus contact with metal | sand; with oak: don't leave iron standing on the top |
| Burn mark | hot pan directly on the wood | sand; deep charring means an insert or replacement |
| Knife marks | cut without a board | sand with the grain and re-oil |
The same applies to all stains: the sooner you deal with them, the less work. A stain you wipe up within a few minutes usually leaves nothing behind. A stain left overnight is in the fibre and has to be sanded out.
Six habits that spare the top
Use a chopping board
Even though it is wood — a knife cutting across the fibre leaves marks you can only remove by sanding.
Trivets for hot pans
A hot pan on an oiled top leaves a burn mark and can make the wood warp. This is the most common irreparable damage.
Dry it straight away
Especially around the sink. Water that stays soaks in and darkens the wood.
No abrasive cleaners
Aggressive cleaners strip the oil out of the fibre. Mild soap and a cloth are enough.
Don't leave iron standing
With oak and other tannin-rich species, contact with iron causes blue-black stains — a wet cast-iron pan does that in one night.
Watch the tap area
Check every month whether water still beads there. That is the spot that asks for oil first.
Frequently asked questions about wooden worktops
How often should I oil a wooden worktop?
Weekly in the first month, monthly for the first six months, and after that two to four times a year. The area around the sink more often than the rest.
How do I know when it's time?
Put a few drops of water on the top. If they stay as beads, there is enough oil in it. If they soak in straight away and the spot darkens, top it up.
Which oil should I use?
An oil suitable for worktops and food contact. Apply it thinly and wipe off the excess after a quarter of an hour.
How do I get a stain out?
Sand lightly with grit 180 to 240, with the grain and over a larger area than the stain, then re-oil.
Can I cut directly on the top?
You can, but the marks stay until you sand them away. A chopping board is simpler than sanding every six months.
What if there is a burn mark?
Surface marks can be sanded out. If the wood is deeply charred, an insert or replacing that part is the only solution.
