How do I clean antique furniture without ruining its value?
Dust it with a soft brush and a vacuum held just above the wood, and do not wipe it if the finish is flaking, lifting or might be original wax. On a sound finish, test a cotton swab of mineral spirits on a hidden spot, wipe grime off with a dampened cotton cloth, and rewax. Never use oil, detergent or abrasive polish.

Step by step
Read when to stop and call a pro, further down this page, before you start.
Step 1: Photograph the piece
Take dated photos of every side, the underside and any label or repair, so you can compare later and show a restorer what you started with.
Step 2: Vacuum with a brush attachment
Hold the brush attachment just above the wood surface and use a soft brush to sweep dust out of crevices and carving toward the nozzle.[1]
Step 3: Use a clean cotton cloth where vacuuming is not an option
Turn the cloth frequently so that accumulated dust does not scratch the surface, and skip feather dusters.[1]
Step 4: Check that the finish is sound
Only furniture with a sound finish should be cleaned, so do not wipe a finish that is flaking or lifting or veneer that is loose; leave it for a restorer.[1]
Step 5: Test mineral spirits on a hidden spot
Dip a cotton swab in mineral spirits and rub a small inconspicuous area; if the finish gets tacky or comes off on the swab, stop.[1]
Step 6: Wipe the grime off
If the test is clean, work in a ventilated area with vinyl gloves and wipe with a cotton cloth dampened with mineral spirits, turning the cloth often, then wipe with a clean, dry cotton cloth.[1]
Step 7: Deal with the rags safely
Store oily and solvent-wet rags in a tightly sealed metal container and then discard them.[2]
Step 8: Rewax a stable clear finish
Mineral spirits dissolve and remove wax, so rewax the cleaned surface with a paste wax not made with strong solvents such as xylene or toluene.[1]
Dust it gently, test anything stronger on a hidden spot, and stop the moment the finish looks fragile. For most antiques the value is in the original surface, so the safest cleaning is the least cleaning: a soft brush and a vacuum held just above the wood, a mineral spirits test on a sound finish, and a light rewax. Never use oil, detergent or abrasive polish.
Dust first, and only dust if the finish is fragile
Dust does more harm than it looks. Because dust is not only abrasive but also attracts moisture, it should be removed periodically to prevent damage as well as to improve the appearance of objects.[1] The National Park Service handbook for its museum collections is the best federal guide to this, and its method is simple.
Use a vacuum with a brush attachment held just above the wood, with a soft brush sweeping dust out of crevices and carving toward the nozzle. Hold the brush attachment just above the wood surface.[1] Where you cannot vacuum, use a clean cotton cloth and turn the cloth frequently so that accumulated dust does not scratch the object's surface.[1] Skip feather dusters, which scatter the dust rather than collect it.[1]
Watch the edges. Dust cloths can catch on loose veneer and pull off pieces.[1]
Check the finish before you clean anything
Only furniture with a sound finish should be cleaned.[1] If the surface is flaking, lifting or has loose veneer, wiping it will cause more harm to flaking and lifting edges or surfaces that have loose veneer or splintered corners.[1] Do not wipe it; leave it for a restorer.
Shellac is the most common finish found on furniture in park museum collections.[1] Shellac is a resin finish, and resins are susceptible to damage from water and alcohol.[1] That is why a wet rag, a glass without a coaster or an alcohol-based cleaner can leave a white mark that is hard to undo.
If you think the piece still has an original wax finish, do not treat it like a modern one. Do not clean a wax finish as you would a hard finish. Consult a conservator for advice.[1]
Cleaning off grime on a sound finish
Mineral spirits are for greasy types of soils and hand oils, the dark film that builds up on arms, drawer fronts and table edges.[1] Test before you wipe. First test a small inconspicuous area with a cotton swab dipped in mineral spirits. If the finish does not get tacky and no finish comes off on the swab, you may begin careful cleaning with a cotton cloth dampened with mineral spirits.[1]
Work in a well ventilated area and wear vinyl gloves,[1] turn the cloth often as it picks up dirt, and wipe the object down with a clean, dry cotton cloth after cleaning.[1] Store oily and solvent-wet rags in a tightly sealed metal container and then discard them.[2]
For smoke or soot, the handbook's method uses a soap such as Vulpex, Ivory or Orvus and water to remove smoke and soot from stable finishes.[1] Follow the maker's dilution instructions, test a small hidden area, wring the cloth well, wipe again with a cloth dampened in clear water, then dry. Never use detergent because it will leave a film on the surface.[1] Do not moisten a damaged, veneered, or inlayed surface.[1]
Rewax, and leave the oil on the shelf
Mineral spirits strip wax, so rewax afterwards: always rewax the finished surface after cleaning, since mineral spirits will dissolve and remove wax.[1] Choose a paste wax, and avoid paste wax made with strong solvents, such as xylene and toluene, because they can damage some finishes.[1]
Do not reach for oil. Do not apply oil to finished wooden surfaces.[1] The handbook warns that in excess linseed oil remains tacky, gathers dust, and severely darkens the wood.[1]
What not to touch
Brass hardware. Polishing brass can damage both the hardware and the surrounding wood.[1] Dull original brass is usually worth more than shiny brass with a ruined finish around it.
Patina. Worn edges, a warm colour and a soft shine are part of an antique's appeal. There is a fine line between patina and a damaged finish,[1] so ask someone who knows the difference before you remove it.
Stop and call a pro if
- The finish is flaking, lifting or crazed, or the veneer is loose. Do not wipe it.
- You suspect an original wax finish. Consult a conservator for advice before you clean.[1]
- The swab comes up tacky or coloured. The finish is dissolving, so stop.
- The piece may be valuable and you are unsure whether cleaning, repair or leaving it alone is right.
- There are small round holes, fine powder, mold or loose joints. The piece needs repair, not cleaning.

Common questions
- Can I use furniture polish or oil on an antique?
- Avoid oil. The National Park Service's museum handbook says not to apply oil to finished wooden surfaces, and notes that in excess linseed oil remains tacky, gathers dust, and severely darkens the wood. A little paste wax on a stable clear finish is the usual alternative.
- Is soap and water safe for antique furniture?
- On a stable finish, the museum method for removing smoke and soot is a soap such as Vulpex, Ivory or Orvus diluted per the maker's instructions, applied with a well wrung cloth after a hidden-spot test, then a wipe with clear water and a dry cloth. Never use detergent, which leaves a film, and do not moisten a damaged, veneered or inlaid surface.
- Should I polish the brass handles?
- Be careful. Polishing brass can damage both the hardware and the surrounding wood, because rubbing with abrasive polishes wears away the brass surface, and the wood finish around and beneath the hardware will likely be damaged. If the hardware is original and only dull, leaving the tarnish is often the safer choice.
- What is patina, and should I clean it off?
- Patina is the distinctive appearance of an older finish: worn but warm, with a soft lustre. There is a fine line between patina and a damaged finish, which is why a restorer should look before you remove anything that might be the first and best surface.
- How often should an antique be cleaned?
- Dust it regularly, because dust is abrasive and attracts moisture. Deeper cleaning for oils and grime should be occasional rather than routine, and only for a sound finish.
