There is a particular impulse that comes over most people when they bring an antique home. The piece has survived a hundred years or more, it has arrived in their care, and the natural response is to want to make it shine. It is a generous instinct. It is also, more often than not, the single greatest risk an object faces once it leaves the dealer's hands.
Almost all the damage we see in pieces brought back to us has been done with good intentions. Bronze stripped of its patina with metal polish. Gilding worn thin by a cloth used too firmly. Enamel lifted by immersion in a solution meant for a plain gold chain. None of it was carelessness. All of it was someone trying to help.
Caring for antiques well is mostly a matter of understanding what a surface actually is, and then doing considerably less to it than you might expect.
What patina is, and why removing it matters
Patina is not dirt. It is the accumulated chemical and physical record of an object's life: oxidation on bronze, the softening of a timber finish, the fine web of surface wear on silver that collectors call bloom. It develops over decades and it cannot be reinstated. A bronze that has been polished back to raw metal has lost something that no amount of subsequent care will return, and with it a meaningful part of its value and its historical legibility.
This is why the first question to ask of any antique is not how to clean it, but whether it should be cleaned at all. Dust is not tarnish. Tarnish is not corrosion. Each calls for a different response, and in many cases the correct response is a soft brush and nothing else.
Silver, and the case for regular gentle use
Silver is the one category where a light routine genuinely helps. Tarnish is a sulphur reaction, and pieces that are used and washed gently tarnish more slowly than pieces left sitting in a cupboard. A silver service that comes out for dinner four times a year will need less intervention than one that has not been touched since it was inherited.
When polishing is warranted, the tools matter more than the effort. A purpose-made impregnated cloth, such as the Goddard's silver polishing cloth we keep in stock, or a gentle paste applied sparingly and buffed off with something soft, will lift light tarnish without abrading the surface. What causes damage is abrasive cleaner, aggressive pressure, and the dip solutions that strip tarnish chemically from every surface at once, including the deliberately darkened recesses that give chased and engraved work its depth.
Two things to avoid entirely: rubber bands, which contain sulphur and will pit silver where they sit, and prolonged storage in an unlined drawer. Anti-tarnish cloth or a lined box will do more to reduce polishing than any polish will.
Our antique silver collection carries more specific guidance on storage, and we are happy to advise on any individual piece.
Jewellery: the materials that should never meet a cleaning solution
Antique jewellery is where the most damage occurs, because a modern ultrasonic cleaner or a jeweller's dip is indiscriminate and antique construction is not.
Organic materials are the first concern. Pearl, coral, jet, ivory, tortoiseshell and amber are porous or structurally fragile, and they will be dulled, cracked or dissolved by solutions that a modern gold ring would shrug off. Pearls in particular should be wiped with a barely damp cloth and nothing more, and put on after perfume rather than before.
Opal and turquoise are similarly vulnerable, opal to sudden changes in temperature and humidity, turquoise to oils and detergents that shift its colour permanently. Emerald is routinely oiled to improve clarity, and cleaning solutions strip that oil out, leaving the inclusions far more visible than when the stone was bought.
Then there is construction. A great deal of Georgian and early Victorian jewellery uses closed-back settings with foil behind the stone to enhance colour. Water that gets behind the setting will tarnish that foil and cannot be removed without dismantling the piece. Enamel, particularly the guilloché and champlevé work found on Victorian and Edwardian pieces, will lift at the edges under immersion. Older settings frequently rely on glue or on shellac-based cements that soften in warm water.
The safe default across almost all antique jewellery is a soft dry cloth, storage in individual pouches so that harder stones do not scratch softer ones, and putting pieces on last when dressing and taking them off first. Our antique jewellery collection pages set out care notes by category, and we will always advise on a specific combination of metal and stone if you are unsure.
Watches sit slightly apart. An antique watch is a mechanism as well as an object, and mechanisms need periodic servicing by a watchmaker who works on period movements. What they do not need is home lubrication, forced winding, or the assumption that a water-resistance rating from the 1930s still means anything.
Furniture, gilding and the Queensland problem
Timber furniture wants stability more than it wants polish. The most damaging thing in a Brisbane home is not neglect, it is the combination of humidity swings and air conditioning, which moves timber against joints and veneers that were made for a different climate. Keeping pieces away from exterior walls, direct sun, and the path of an air conditioning outlet will do more for their longevity than any product.
Where a finish does need attention, a good quality wax applied thinly, infrequently, and buffed properly is the traditional approach. Silicone-based aerosol sprays are not: they build a film that yellows, resists later waxing, and complicates any eventual restoration. Oil finishes and wax finishes are also not interchangeable, and applying one over the other creates problems that a restorer then has to undo.
Gilded surfaces, whether on a frame, a mirror, or carved furniture, should be dusted with a soft brush and never with a cloth, which catches on the gesso and lifts it. Water on water gilding will simply remove it. This applies equally to antique mirrors, where the additional risk is moisture getting behind the plate and causing the mottled deterioration known as foxing. Clean the glass with a lightly dampened cloth rather than spraying anything directly onto the surface.
Bronze sculpture follows the patina principle absolutely. Dust it, protect it where appropriate with a thin application of microcrystalline wax, and keep metal polish away from it entirely. Marble and stone should be dusted only, since water and household cleaners cause staining that sits below the surface and cannot be lifted out.
When to stop and call someone
The line is simpler than it looks. Routine dusting, gentle surface cleaning appropriate to the material, and sensible storage are the owner's job. Anything structural, anything that involves solvents, anything that involves removing an existing finish, and anything on a piece of genuine significance belongs with a specialist.
That includes silversmithing repair for dents, splits or worn gilding, which is an established craft and entirely achievable in skilled hands. It includes paintings conservation, where surface cleaning and varnish removal can transform a work that looks irretrievably dull, but only when carried out by a qualified conservator. It includes furniture restoration, where the judgement about how much to do is as important as the technique.
We do not carry out restoration ourselves, but we can refer you to practitioners we trust, and we would always rather have that conversation before work begins than assess the results afterwards. Where restoration has been carried out on a piece in our collection, it is documented and disclosed, which is the same standard we would expect any dealer to hold.
The underlying principle
An antique that has reached you in good condition has done so because a series of previous owners were, on balance, restrained. Objects are rarely lost to neglect. They are lost to enthusiasm.
The most useful thing a collector can do is to understand what they are holding well enough to know when to leave it alone. If you own something and you are not certain, ask before you act. We would far rather answer a question about a piece than see it corrected later.
More detail on our authentication and documentation process is set out in our FAQ, and we are always available to discuss the care of any piece, whether it came from us or not.
