Why old wood responds well to gentle treatment

Most pieces of furniture that come out of British farmhouses, cottages and terraced houses have already been finished with something. It might be beeswax, linseed oil, a shellac french polish, or simply decades of furniture cream and elbow grease. What looks like grime is often a patina built up over a hundred years of use, and it is worth protecting.

Chemical strippers and heavy sanding remove that patina in an afternoon. They also leave bare timber that is pale, thirsty and prone to staining. The gentler approach — clean, feed, protect — takes longer, but the result is a finish you can repair with a cloth rather than a confession. It suits the way most of us actually live: a scrubbed kitchen table, a chapel chair by the fire, a gateleg table that has been in the family since before anyone can remember.

Cleaning before you touch a sanding block

Before any abrasive work, clean the surface. A cloth wrung out in warm water with a drop of washing-up liquid will lift dust and grease from the grain. Dry it straight away with a towel. Where there is a heavy build-up of old wax or sticky polish, dampen a cloth with white spirit and work in small circles, testing first on the underside or the back of a leg where any dulling will not show.

Then sand, but lightly. Start with 120 grit only where the surface is genuinely rough or has raised grain, move to 180, and finish with 240. Always work with the grain. On turned legs and carved detail, wrap the paper around a cork block or a dowel and follow the shape rather than flattening it. A belt sander is the wrong tool for a chair: it cuts hollows that are almost impossible to disguise, and it rounds over the crisp edges that give old furniture its character. Finish with a rub of 0000-grade wire wool, then wipe away every trace of dust with a tack cloth or a cloth dampened with white spirit.

Feeding the wood with linseed oil

Oil replaces what time and central heating have drawn out of the timber. Raw linseed oil is the traditional choice — deep, golden and slow, sometimes taking weeks to cure properly. Boiled linseed oil contains driers, so it hardens in a day or two and is easier to live with in a busy house, though it is less pure.

Warm the oil gently by standing the tin in a bowl of hot water. Apply it with a lint-free cloth, working it well into the grain, then leave it for twenty to thirty minutes and wipe off everything the wood has not absorbed. This last step matters: excess oil left sitting on the surface turns tacky and attracts dust. Thin coats, three or four of them, a day or two apart, will give a far better result than one generous soaking.

Take care with the rags. Linseed-soaked cloth can generate heat as it dries and has been known to catch fire. Spread them flat outdoors to dry, or submerge them in water before binning them.

Wax for a soft sheen and lasting protection

Wax sits on top of the oiled surface, adding sheen, scent and a degree of water resistance. A beeswax-based furniture wax is ideal, or you can make your own by melting one part beeswax into three parts turpentine in a jar set in warm water — never over a direct flame.

Apply a thin smear with a cloth, working it into the grain rather than across it, then leave it for fifteen to twenty minutes until it hazes over. Buff with a clean cloth or a soft shoe brush until the surface feels dry and slightly slippy under the fingers. Two thin coats always beat one thick one. Oak and ash will darken a shade; pine and beech warm towards honey. That change is not a fault — it is the timber showing its age gracefully.

Small repairs worth doing first

• Loose joints. Use animal glue, warmed in a double boiler. It is strong, traditional, and reversible with warm water if the repair ever needs undoing. Work it into the joint, clamp firmly, and wipe the squeeze-out away with a warm damp cloth.
• Wobbly chairs. Check the stretchers and the leg joints before gluing the seat. A chair that rocks is rarely fixed by treating the symptom.
• Scratches. Rub along the grain with a walnut kernel, or press a little beeswax into the line with a fingertip and buff it level.
• Dents in the surface. Lay a damp cloth over the dent and press with a warm iron for a few seconds at a time. The steam swells the crushed fibres. Do not scorch the wood, and do not try it on a varnished finish.

Living with an oiled and waxed finish

An oiled surface asks for a little attention each year, and gives a great deal back. Re-wax every six to twelve months, more often in a dry, centrally heated room. Keep pieces away from direct sun and from the immediate blast of a radiator or wood burner, and consider a bowl of water nearby in winter to lift the humidity.

Dust with a dry cloth rather than a silicone spray polish, which builds up a film that makes any future refinishing far harder. And when a scratch does appear, treasure the fact that you can blend it with a little wax and a warm afternoon rather than reaching for a chemical stripper. Waxing a table on a quiet Sunday, with the smell of beeswax and linseed in the room, is one of the small, slow rituals that keeps a house feeling lived in.
