Cleaning Antique Furniture: What You Need to Know

A client in Clifton Village once asked me to “give her dining table a good polish.” It was a Georgian mahogany table worth about £30,000. The last cleaner had used spray polish from a supermarket. Six months of silicone buildup had turned the surface cloudy and sticky.

That table needed professional stripping and re-waxing. A £400 job to undo damage caused by a £3 can of polish.

Antique furniture deserves better.

General Principles: Less Is More

The single most important rule for antique furniture: do as little as possible. Not nothing. But far less than most people think.

Antique furniture has survived decades or centuries. It doesn’t need aggressive intervention. It needs gentle, regular care that preserves what’s already there.

Don’t strip it. Original finishes have value. A 200-year-old patina on a piece of oak is part of its character and its monetary worth. Stripping it away is destroying history.

Don’t modernise it. Don’t apply polyurethane varnish to a shellac-finished surface. Don’t use modern stains on period wood. The materials should match the era.

Test everything. Any product, any method, any cloth, test it first on the least visible area. The underside of a table leaf. The back of a cabinet. Inside a drawer.

Dust regularly. The best thing you can do for antique furniture is keep it dust-free. A soft, dry cloth or a gentle feather duster, used weekly, prevents the buildup that leads to heavier intervention later.

Wood: Beeswax, Not Spray Polish

Most antique wooden furniture has one of three finishes: wax, shellac (French polish), or oil. Each needs different care, but they all share one common enemy: modern spray polish.

Why spray polish is the enemy. Most aerosol furniture polishes contain silicone. Silicone creates a temporary shine but builds up layer by layer into a sticky film. It penetrates the grain and is incredibly difficult to remove. Worse, silicone contamination makes future refinishing nearly impossible without aggressive stripping.

Waxed surfaces (most common on English antiques):

• Dust with a soft cloth
• Apply a thin coat of good beeswax paste once or twice a year
• Buff with a clean cotton cloth
• Never use water. It raises the grain and can white-mark the surface
• Remove marks with a very fine application of wax and gentle rubbing

French polished surfaces (shellac):

• Dust only. Shellac is soluble in alcohol, so keep drinks away
• Water marks show instantly. Wipe any moisture off immediately
• Professional re-polishing by a French polisher when the surface deteriorates
• Don’t attempt to touch up French polish yourself unless you know what you’re doing

Oiled surfaces (common on oak and Scandinavian pieces):

• Dust regularly
• Reapply appropriate oil (Danish oil, tung oil, linseed oil depending on the original finish) annually
• Wipe off excess oil thoroughly after application
• These finishes are the most forgiving, they can be topped up easily

Honestly, I’ve seen more damage done to antique furniture by over-enthusiastic cleaning than by neglect. A piece that’s been left alone for 20 years is usually in better shape than one that’s been spray-polished every week.

Upholstered Antiques: Gentle Vacuum, Handle with Care

Antique upholstery ranges from sturdy Victorian horsehair to fragile 18th-century silk. The fabric dictates the approach.

General rule: vacuum gently. Use the upholstery attachment on your vacuum cleaner at the lowest suction setting. Hold the nozzle just above the fabric rather than pressing it into the surface. For fragile fabrics, place a piece of mesh or muslin over the fabric and vacuum through it. That prevents the suction from pulling at weakened threads.

Never use water on silk. Period silk upholstery is often weighted with metal salts (a historical manufacturing process). Water causes these salts to react, weakening the fabric and causing discolouration. Professional dry cleaning only.

Leather upholstery on antiques:

• Dust with a soft cloth
• Clean with a leather cleaner formulated for aged or antique leather
• Condition sparingly. Old leather is dry for a reason. Over-conditioning makes it soft and can cause it to stretch or sag
• Never use modern furniture leather products. They’re formulated for modern tanned leather, which is chemically different

Needlepoint and woven covers:

• Vacuum through a screen (mesh or muslin)
• Never wash. Never wet clean
• Spot cleaning with extreme caution if absolutely necessary
• Professional textile conservation for anything valuable or damaged

What to avoid on all antique upholstery:

• Steam cleaning (too much moisture and heat)
• Fabric freshening sprays (chemicals can react with old dyes)
• Rubbing at stains (weakens fabric and spreads the stain)
• Direct sunlight (rotate furniture or use blinds to prevent uneven fading)

Metal and Gilding

Antique furniture often incorporates metal elements: brass handles, ormolu mounts, gilded decoration, iron hinges.

Brass and bronze:

• Don’t over-polish. The green-brown patina on antique brass is called verdigris. On quality pieces, it’s valued by collectors. Polishing it off reduces the piece’s appeal and value.
• If cleaning is needed, use a metal polish appropriate for the specific metal. Apply sparingly. Buff gently.
• Lacquered brass should only be wiped with a dry cloth. If the lacquer is failing, it needs professional removal and reapplication.

Gilding:

• Never touch gilding with anything wet. Ever.
• Dust very gently with a soft, dry brush (a clean makeup brush works well)
• Water leaf gilding (common on older pieces) is applied with only water as the adhesive. Moisture will loosen and destroy it
• Oil gilding is slightly more durable but still sensitive to chemicals and abrasion
• If gilding is damaged or lifting, contact a specialist gilder. Don’t try to fix it

Iron hardware:

• Wipe with a dry cloth
• A very light application of wax prevents rust
• Don’t oil iron hinges on furniture. Oil attracts dust and creates a paste that accelerates wear
