Wooden kitchen worktops need regular maintenance for longevity. Restoring and resurfacing worksurfaces doesn’t need specialised knowledge. You just need some basic tools and the right product to apply to the surface.
Most homeowners will be able to do this maintenance themselves. This guide will give you an overview of how to clean, sand, and refinish wooden worktops with food safe and breathable products.
How to Prep Wooden Worktops Before Restoration
Cleaning is the first step in any restoration because dirt or grease will stop oil from soaking into the wood. Failing to remove dirt and grease can lead to a patchy and uneven finish.
For cleaning before re-oiling, use a plant based cleaner such as Auro Paint and Stain Cleaner No. 435. This removes grease and residues without leaving a film that interferes with absorption. Once the surface is clean, allow it to dry completely. If any areas feel rough, a light pass with a fine sanding pad will smooth the grain ready for oil.
Why Oil is Best for Refinishing Worksurfaces
The best way to refinish a wooden kitchen worktop is with oil, because it penetrates the grain, enhances the natural look and stays easy to refresh with simple maintenance coats.
Varnish is not ideal for worktops because it forms a hard surface film that chips, scratches and traps moisture, and once damaged it usually requires sanding back the entire area rather than a quick touch up. An oiled finish remains breathable, repairable and far more practical for real world kitchen use.
How to Restore a Wooden Worktop With Oil
After cleaning, you can begin the process of restoring and refinishing your worksurface.
- Clean the surface thoroughly so it is free from grease, residue and everyday grime.
- Assess the condition of the wood - If the finish still feels smooth and mostly intact, a light re-oil is usually enough. If the worktop looks grey, patchy, dry or worn, it will benefit from a light sanding.
- Sand only if needed, using fine sandpaper such as 240 grit. Always sand along the grain to avoid visible scratches.
- Remove all sanding dust by vacuuming the surface and wiping it down with a dry cloth.
- Check the surface for smoothness. The wood should feel clean, dry and even before re-oiling.
- Once dust free and smooth, the worktop is ready for oiling with thin, well absorbed coats.
Tip: Wood around sinks and end grain areas sometimes needs extra attention because these are the parts that absorb the most moisture. Extra thin coats here will extend the life of the finish significantly.
What Are The Best Kitchen Worktop Oils?
Natural wood oils are the best choice for maintaining wooden worktops because they sink into the grain, nourish the timber and create a breathable, food safe surface that can be refreshed without sanding.
Auro Worktop Oil 108 is a solvent free hard oil based on tung oil, linseed oil, sunflower oil and castor oil. It is EN 71-3 certified for toy safety, food safe once dry and very durable. It strengthens the surface, improves abrasion resistance and reduces dirt penetration.
Loxxin Hemp Oil is a single ingredient option made from 100 percent UK grown organic hemp. It is food safe, odour mild and easy to apply. Hemp oil soaks deeply into the grain and gives a natural matte finish.
Osmo Top Oil is an oil and wax blend based on natural vegetable oils and waxes. It is resistant to wine, coffee, tea, fruit juice and everyday spills, which makes it a strong choice for busy kitchens. The finish is microporous, safe for children’s toys and food safe when dry.
Each product differs slightly in appearance, durability and feel, so it is worth testing on an inconspicuous area before committing to a full coat. All three are suitable for routine maintenance and patch repairs.

How to Maintain Oiled Kitchen Worktops
An oiled worktop stays at its best with occasional maintenance rather than major restoration after the surface begins to degrade. New worktops need oiling once a week for the first six weeks. This builds a strong foundation and helps the surface resist water.
After that, most kitchens only need a maintenance coat every three to six months. The simplest way to know if it is time to reapply oil is to perform a water test. Sprinkle a few drops of water on the surface. If the droplets bead up, the protection is still working. If the water spreads or begins to soak in, it is time for another coat.
Frequently Asked Questions About Wooden Worktop Care
Why is my wooden worktop sticky after oiling?
A worktop becomes sticky when excess oil sits on the surface instead of soaking into the wood. This happens when the coat is too thick, when the surplus is not wiped away or when the wood was sanded too smoothly for the oil to absorb properly. The simplest fix is to wipe the area with a cloth lightly dampened with white spirit to remove the residue. If the stickiness remains, sand lightly and apply a very thin fresh coat, wiping away all excess.
How long should I leave a worktop after oiling?
Most oils need eight to twelve hours to dry between coats. Press your hand against the surface to check. If it feels smooth and dry, you can proceed. If it feels tacky or slightly grabs your skin, it needs more time.
How many coats of oil do worktops need?
A new worktop generally needs three to seven thin coats to build an even, protective finish. Once established, maintenance typically requires one to three coats, applied whenever water no longer beads on the surface.
Should I oil both sides of a worktop?
Both sides should be oiled before installation. After fitting, only the top surface needs ongoing maintenance.
What oil penetrates wood best?
Low viscosity natural oils such as hemp, tung and linseed penetrate deeply because they soak into the fibres rather than forming a film. Hardwax oils offer better day to day protection even though they do not penetrate as far.
Is Danish oil good for worktops?
Danish oil is easy to use and gives a warm finish, but it does not offer the same level of water resistance or durability as a dedicated worktop oil. It suits low traffic kitchens but needs more frequent reapplication.
Is tung oil better than Danish oil?
Tung oil is more natural and gives a matte finish, but it dries slowly and needs more upkeep. Danish oil dries faster and is slightly more durable, but both are outperformed by modern hardwax oils in busy kitchens.
Can I use olive oil on wood?
Olive oil should not be used because it goes rancid and can encourage bacterial growth. Food grade mineral oil, hemp oil or specialist worktop oils are better choices.
How often should I oil wooden worktops? Once a week for the first six weeks, then every three to six months or whenever the water test shows it is needed.
