A few months ago, a client wrote to us with a photo and an apology.
The photo showed the top of her dresser, purchased here a couple of years earlier. It had a white ring the size of a water glass and an area where the varnish had become sticky.
The apology was for the latter. She had been "caring for" it weekly with a supermarket polishing spray. One of those that smells clean and makes wood shine like a mirror.
The ring was an easy fix. The spray, not so much: the silicone in those products builds up layer by layer, traps dust, dulls the tone, and, over time, makes it almost impossible to touch up the finish without stripping it completely.
She hadn't done anything unusual. She had done what almost everyone does. And that is exactly the problem.
A restored antique piece of furniture asks for almost nothing. But the little it asks for is the opposite of what cleaning product advertising tells you.
First, the good news: it needs less than you think
When a piece leaves the workshop, it has a revised structure, wood treated against wood borers, and a hand-finished, stable surface. It's not a sick patient that needs constant monitoring. It's a piece of furniture that has already proven to last a hundred years and, placed correctly, will last the next hundred without asking for almost anything from you.
Real maintenance comes down to three things: dusting it, protecting it from two specific enemies, and, from time to time, nourishing the finish. Everything else is unnecessary. And a good part of everything else, besides being unnecessary, causes damage.
The two real enemies: sun and heating
Old wood does not die from use. It suffers from the environment.
Direct sunlight fades. A piece of furniture next to a south-facing window will lose color unevenly: the area facing the light will lighten and the shaded area will not. It's not noticeable in a few months; in two years, it is. The solution is not to hide the furniture: it's to prevent the sun from hitting it directly for the same hours every day. A sheer curtain is enough. Rotating the piece occasionally also helps.
Dry heat is worse, and it's coming now. When the heating is turned on in October, the air humidity plummets and the wood, which is a living material, contracts. That's when fine cracks appear on tops and sides, joints become prominent, and, in veneered furniture, some lifting occurs.
The three rules we provide with every piece:
Never next to a radiator. At least one meter away; if the radiator is on the only possible wall, an insulating sheet behind the furniture helps, but it's a patch-up.
Be careful with strong underfloor heating. It's the most silent enemy because it heats exactly where the furniture breathes the least. If you have it, keep the temperature moderate and monitor the legs and plinths during the first winter.
Sudden changes do more damage than cold or heat itself. A village house closed all winter and heated to the maximum on weekends punishes the wood more than a house kept at a moderate temperature all year round.
Weekly cleaning: a cloth and that's it
Dust with a soft, dry cloth, cotton or microfiber. Following the grain, without pressing. That's all.
If there's a stain, a barely damp and very wrung-out cloth, and dry immediately with another dry one. Water is the enemy of any old finish: never a soaked cloth, never let a liquid dry on the wood by itself.
And glasses, with coasters. The white ring our client mentioned at the beginning was just that: moisture trapped under the varnish. It can be fixed in the workshop, but not at home, and internet remedies (iron, mayonnaise, hairdryer) end badly more often than not.
What you should never do
This list exists because everything it contains has ended up in our workshop.
Polishing sprays with silicone. The case of the dresser. They leave an instant shine and an accumulating problem: layer after layer of silicone that dulls the patina and complicates any future restoration. If the bottle doesn't say what it contains, don't use it.
Multi-purpose cleaners, ammonia, and alcohol. They dissolve or cloud old finishes, especially traditional varnishes. An antique piece of furniture is not cleaned with the same products as a countertop.
Wet wipes. They contain detergents and moisture, both at once. Convenient for everything except wood.
Cooking oils or "homemade remedies" with vinegar. Olive oil goes rancid on wood and vinegar is an acid. Both appear in a thousand internet tricks. Both end up on our workbench.
Waxing or oiling a varnished piece of furniture. Each finish has its own maintenance. Wax works well on waxed finishes; on a varnish, it just makes a mess. If you don't know what finish your piece has, ask us before buying the product: it's a message that saves you a headache.
And the biggest one of all: sanding or stripping at home "to renew it." The patina of an antique piece of furniture, that deep tone given by time, takes a hundred years to develop and is destroyed in an afternoon of sanding. It doesn't come back. If a finish is truly damaged, it's a workshop job, not a weekend project. We already explained when it makes sense to wash a piece of furniture and leave it in natural wood — and when it's an irreversible mistake.
Real maintenance: once or twice a year
For a waxed piece of furniture or one with a traditional finish, a quality wax—beeswax, without silicones—once or twice a year. A small amount, in a thin layer, following the grain, and buff to a shine with a clean cloth when dry. More wax does not mean more protection: it means more accumulated gunk.
For a varnished piece of furniture, not even that: a dry cloth and a stable environment. Varnish is already the protection.
For hand-painted pieces and stripped finishes, the same: a dry or barely damp cloth, and no waxes or products. Stripped finishes are made to age with dignity, not to shine.
Period hardware, handles, and keyholes are cleaned dry. Aggressive metal cleaners remove the original gilding or bluing, and that finish, once gone, does not return.
And the marble tops: it's stone, but not invincible. Acids—lemon, wine, vinegar—stain it if left on. Clean with water and neutral soap, dry, and that's it.
What to check once a year (and when to call us)
A five-minute check every autumn, before turning on the heating:
That drawers slide and doors close as usual. A drawer that starts rubbing in October is usually the wood moving with the change of season; it almost always returns to normal in spring.
That there are no new small holes with fine sawdust underneath. This is a sign of active woodworm, and we explain it thoroughly in the honest guide to woodworm. Workshop pieces leave treated, but woodworm can come from another piece of furniture in the house.
That no leg wobbles. A wobbly piece of furniture is easily and quickly corrected; a piece of furniture that has been wobbly for two years has been straining its joints every day.
If any of this appears on one of our pieces, write to us with a photo before touching anything. We have been restoring these pieces of furniture in the Navalcarnero workshop since 2015 and have seen more damage caused by well-intentioned home repairs than by the passage of time. More than 3,500 families have bought from us, and the least visible part of that number is this: continuing to respond after delivery.
A piece of furniture that already knows how to last
All of this can be summed up in one sentence: dry cloth, away from the radiator, and when in doubt, ask.
The rest is up to the furniture. It's been practicing for a century.

Frequently Asked Questions
How do I clean antique furniture daily?
With a soft, dry cloth, following the grain. For stains, a barely damp and very wrung-out cloth, drying immediately. No multi-purpose cleaners, silicone polishing sprays, or wet wipes: all three damage antique finishes.
How often should antique furniture be waxed?
Only if the furniture has a waxed or traditional finish: once or twice a year, with silicone-free beeswax, in a thin layer. Varnished furniture is not waxed, and hand-painted or stripped pieces are not either: in these cases, a dry cloth is sufficient.
Can I place antique furniture in a house with underfloor heating?
Yes, with caution. Dry, constant heat from below is what contracts the wood the most, so it's advisable to maintain moderate temperatures, avoid sudden changes, and monitor the piece during the first winter. And always away from radiators: at least one meter away.
What should I do if my furniture gets a white ring or a stain?
Do not apply home remedies: an iron, mayonnaise, or vinegar worsen more cases than they fix. A white ring is moisture trapped under the finish and is corrected in a workshop. If the piece is ours, write to us with a photo and we will tell you how to proceed before touching anything.
