A well-restored mid-century piece is not a finished project. It is a living thing, timber that still breathes, leather that still needs feeding, fabric that still wants light and air in the right amounts and none of the wrong ones. Look after it properly and a piece that has already survived fifty or sixty years will comfortably survive another fifty. Neglect it, and even the best restoration in the world will start to fade, dry out or crack within a few short years.
This guide covers the three materials that make up almost everything we restore in our Torquay studio timber, leather and fabric upholstery and the small, unfussy habits that keep each of them in condition. None of it takes more than a few minutes a month. All of it is worth doing properly.
Why Mid-Century Furniture Needs Different Care to New Furniture
Most furniture made today is designed to be replaced, not repaired. It is sprayed, laminated or veneered over particleboard, and once the finish fails there is often nothing underneath worth saving.
Mid-century pieces from the 1950s through the 1970s were built the opposite way. Solid timber, hand-cut joints, natural oil or lacquer finishes that were designed to be maintained and touched up over decades, not replaced after a few years. That is precisely why they have lasted this long and why the ongoing care they need is different from what you'd do with a flat-pack sideboard. You are not just cleaning it. You are maintaining a finish that was built to be renewed.
The condition of a piece is also, honestly, most of what it's worth. A Danish sideboard with dry, grey timber and a leather chair with cracked, sun-bleached hide will always be worth less than the same piece kept oiled, conditioned and out of direct sun — regardless of the maker's name on the back. Good care isn't just about how a piece looks. It's what protects the investment.
Timber Care: Teak, Walnut, Rosewood & Australian Blackwood
Timber is the part most people get nervous about, and it's actually the most forgiving of the three materials — as long as you follow a few basic rules.
Dust it regularly, and dust it properly
Dust weekly, or more often if the piece sits near an open window or a well-used room. Use a soft, dry, lint-free cloth and go with the grain. Skip feather dusters (they just push dust into the grain) and skip furniture sprays with silicone in them — silicone builds up in the grain over time and interferes with future oiling or refinishing.
Oil it every six to twelve months
This is the single most important habit for teak, walnut, rosewood and blackwood. Original mid-century finishes were almost always a penetrating oil finish, not a hard lacquer, which means the timber needs feeding from time to time or it dries out, greys and eventually cracks.
-
How often: every six to twelve months for pieces indoors, more often if the room gets a lot of sun or the piece sits near a heater or vent
-
What to use: a proper Danish oil or teak oil — never olive oil, cooking oils or generic "furniture polish," which sit on the surface rather than feeding the timber and can go rancid or sticky
-
How to tell it's due: if the surface looks dull, feels dry to the touch, or a splash of water doesn't bead slightly on the surface, it's time
-
How to apply: wipe on a thin, even coat with a soft cloth, following the grain, let it sit for ten to fifteen minutes, then wipe off any excess with a clean cloth. Let it cure overnight before putting anything back on the surface
Less is more here. A thin coat that's fully wiped off will always look and perform better than a heavy coat left to sit.
Keep it out of direct sun and away from ducted heating
Both cause the same problem from opposite directions: the timber dries out faster than you can oil it, and colour fades or shifts unevenly. If a piece has to sit in a sunny spot, rotate it occasionally so it fades evenly, and oil it a little more often than you would elsewhere in the house.
Deal with spills and rings immediately
Wipe up any spill straight away with a soft, slightly damp cloth, then dry the area fully. A ring or a light water mark can usually be worked out with a very light pass of 0000-grade steel wool along the grain, followed by a fresh coat of oil. Leave a spill sitting overnight and you're looking at a stain that's much harder to shift.
What we don't do and why
We don't spray polyurethane over restored timber, and if you ever have a piece refinished elsewhere, it's worth asking your restorer the same question. Polyurethane looks glossy and "finished" for about a year, then it starts to fail and because it's a hard film sitting on top of the timber rather than soaked into it, it can't be touched up.
The whole surface has to be stripped back and redone. An oil finish can be touched up at home, in an afternoon, for the rest of the piece's life. That's the whole point.
Leather Care: Keeping Original and Reupholstered Leather Supple
Leather is more forgiving than people expect, and less forgiving of a handful of specific mistakes than people realise.
Weekly maintenance
Wipe leather down with a dry, soft microfibre cloth to lift dust, then vacuum gently into seams and piping using a soft brush attachment, this is where grime actually collects and does the most damage over time.
Condition it two to four times a year
Leather is skin, and skin needs oils replaced as they naturally dry out. Use a leather conditioner made for furniture not a shoe or car product, which are often formulated differently.
Apply a small amount to a cloth (never directly onto the leather), work it in with circular motions, leave it to absorb for ten to fifteen minutes, then buff off any excess with a clean, dry cloth.
Test any product on a hidden patch first always
Under a cushion, on the underside of an arm, anywhere that won't be seen. Aniline leather in particular has no protective topcoat, which gives it that beautiful, natural look but also means it absorbs whatever you put on it, including moisture and colour from cleaning products. If you're not certain what leather you're dealing with, treat it as aniline and be conservative.
Cleaning spills and marks
Blot don't rub with a dry cloth first. For anything beyond dust, use the smallest amount of water possible on a barely damp cloth, working in small circular motions, then dry immediately with a separate cloth. Skip baby wipes, alcohol-based cleaners and anything with ammonia; all three strip the natural oils out of leather over time and accelerate cracking.
Keep it out of direct sun and away from heat sources
Same rule as timber, doubled. Leather dries and cracks faster than almost any other material in direct sun, and heating vents will do the same thing from a different angle. If a leather piece has to live in a sunny room, condition it more often every eight to ten weeks rather than every few months and consider a UV-filtering window film if the spot is unavoidable.
Upholstery Care: Fabric, Velvet & Bouclé
When we reupholster a piece, we use commercial-grade designer fabrics, often treated for stain resistance which makes day-to-day care fairly straightforward, provided you get ahead of spills rather than behind them.
Vacuum weekly
A soft upholstery attachment, low suction, working with the direction of the weave rather than against it. This is the single biggest factor in how long fabric upholstery lasts, because it's ground-in dust and grit not sunlight or use that cuts fibres from the inside.
Rotate and flip cushions
Every few weeks, if the cushions are reversible or removable. Even wear is the difference between a seat that still looks new after five years and one with a visibly worn patch after eighteen months.
Treat spills immediately, and always blot
Never rub rubbing pushes the spill deeper into the fibres and can spread the stain. Blot from the outside of the mark inward with a clean, dry cloth to lift as much as possible before it sets, then follow the fabric's specific cleaning code if you know it (most commercial-grade fabrics come with a cleaning code W for water-based cleaners, S for solvent-based, WS for either, X for vacuum only).
Keep pets' claws and direct sun in mind
Trim pets' nails regularly if they share the sofa, and keep upholstered pieces out of harsh, direct sun where possible fading on fabric is much harder to reverse than on timber or leather, and there's no equivalent of an oil or conditioner to bring the colour back.
When to call in a professional
Any deep stain, a tear, or upholstery more than a decade old that's starting to lose its shape is a job for a professional upholsterer, not a home remedy. Trying to fix it yourself with the wrong product can set a stain permanently or damage the fabric in a way that's no longer repairable.
A Simple Care Routine You Can Actually Stick To
-
Weekly: dust timber, vacuum upholstery and leather seams
-
Monthly: check for dryness on timber and leather, rotate cushions
-
Every 6–12 months: oil timber, condition leather
-
Ongoing: keep everything out of direct sun and away from ducted heating, and treat every spill the moment it happens
Conclusion
Caring for mid-century furniture isn't complicated, and it definitely isn't precious it's a handful of small habits, repeated consistently, that add up to a piece looking as good in another fifty years as it does today. Dust and oil the timber, condition the leather, vacuum the fabric, and keep everything a sensible distance from direct sun and heating vents. That's genuinely most of it.
If you already own a piece that's dried out, cracked or worn through, it's very rarely beyond saving that's the whole reason mid-century furniture holds up so well against anything made to be replaced.
Our furniture restoration service in Torquay handles everything from a simple re-oil to a full strip-back and reupholster, and if you're searching for a specific piece to bring into a well cared-for home, our current collection is a good place to start.

Frequently Asked Questions
How often should I oil teak furniture?
Every six to twelve months for pieces kept indoors, and more often every three to four months if the piece gets regular direct sun or sits near a heater. A simple test: if a few drops of water don't sit slightly beaded on the surface, or the timber looks dull and dry, it's due.
What's the difference between teak oil and Danish oil?
Both are penetrating oil finishes rather than surface coatings, and either works well on mid-century timber. Teak oil is formulated specifically for oily hardwoods like teak; Danish oil is a slightly more general-purpose blend of oil and varnish that also suits walnut, rosewood and Australian blackwood. Avoid cooking oils, furniture polish or anything silicone-based — none of them feed the timber the way a proper oil does, and some can leave a residue that interferes with future restoration.
Can I use olive oil or vegetable oil on wood furniture?
No. This comes up a lot, and it's worth being direct about: kitchen oils don't cure or absorb the way furniture oils do. They sit on the surface, attract dust, and can go rancid over time, leaving a smell that's genuinely difficult to remove. Stick to a proper teak or Danish oil made for furniture.
How do I clean a vintage leather chair without damaging it?
Start with the gentlest option a dry, soft cloth to remove dust, then a barely damp cloth if more is needed. Test any cleaning product on a hidden patch first, particularly with aniline leather, which has no protective topcoat and absorbs whatever touches it. Condition every few months to keep the leather supple, and skip household cleaners, baby wipes and anything alcohol-based, which dry leather out faster than sunlight does.
Why does old teak furniture turn grey?
Grey, dry-looking timber is almost always sun exposure combined with a finish that hasn't been oiled in a while it's not damaged, and it's usually reversible. A light pass with fine steel wool along the grain to lift the greyed surface layer, followed by a fresh coat of oil, will generally bring the colour and depth back.
Is it normal for vintage leather to have some cracking or fading?
A little surface character softening, a slight sheen change, minor colour variation is part of what makes vintage leather look the way it does, and most collectors consider it part of the piece's story rather than a flaw. Deep cracking, flaking or stiffness is different, and usually means the leather has dried out from sun exposure or gone too long without conditioning. Caught early, most of it can be brought back with regular conditioning; left too long, it may need professional attention.
How do I know what cleaning products are safe for my upholstery fabric?
Most commercial-grade upholstery fabric comes with a cleaning code — W for water-based cleaners only, S for solvent-based only, WS for either, and X for vacuum only, no liquid at all. If you're not sure which applies to a piece you already own, treat it as X until you can confirm, and always test any product on a hidden section first.
How do I restore a mid-century sideboard that's been neglected for years?
It depends on how far gone it is. Surface dryness and greying can often be fixed at home with fine steel wool and a fresh coat of oil. Deeper damage loose joints, water damage, failed old finishes, veneer lifting is a job for a professional restorer, since a rushed fix can make the underlying problem harder to repair properly later. If you're unsure which category a piece falls into, our restoration team is happy to take a look.
