How to clean wood furniture without damaging the finish

Step by step: how to clean wood furniture without damaging the finish

1. 1

   Find out what finish you have

   Most furniture made in the last few decades has a hard finish like lacquer, varnish or polyurethane, which tolerates a damp wipe. Oiled, waxed, shellac and antique finishes are more delicate. Dab a drop of water in a hidden spot: if it beads, the finish is sealed; if it soaks in or turns white, keep water to a minimum.

2. 2

   Dust with the grain

   Wipe the whole piece with a soft, dry or very slightly damp microfiber cloth, following the direction of the wood grain. Fold the cloth so you always use a clean side. Dust is abrasive, so this weekly step is what keeps the finish from going dull.

3. 3

   Wash off grime with a barely damp cloth

   Add a few drops of mild dish soap to a bowl of warm water. Dip a cloth, wring it until it is almost dry, and wipe one section at a time. You should see fingerprints, grease and sticky marks come off on the cloth.

4. 4

   Rinse and dry immediately

   Wipe the same section with a second cloth dampened in plain water to remove soap, then dry it right away with a dry towel. Never leave water standing on wood, and never soak it; water can cloud the finish and swell the wood.

5. 5

   Clean carvings and handles

   Use a soft toothbrush dipped in the soapy water and well shaken off to clean carved details, corners and around hardware. Dry with a cloth wrapped around your finger.

6. 6

   Cut through old polish buildup

   If the surface feels sticky or looks smeary even after washing, it likely has layers of old spray polish. Use a wood cleaner made to remove wax and silicone buildup, or test odorless mineral spirits on a hidden spot and wipe with a soft cloth, working with the grain and with windows open. Wipe dry when done.

7. 7

   Polish or wax sparingly

   Apply a silicone-free polish or a thin coat of paste wax with a soft cloth, then buff with a clean cloth. Polish every few months at most; more just builds up. Dusting is enough the rest of the time.

How do you clean wood by finish type?

Sealed finishes can be wiped with a damp, soapy cloth; oiled and waxed finishes should be dusted and only lightly damp-wiped; antiques and shellac need the gentlest touch.

For wood floors, the rules are different; see how to clean hardwood floors.

Is it dirty, or is the finish worn out?

Cleaning only fixes dirt and buildup. A lot of “dirty” wood is really a finish that has worn through or broken down, and more scrubbing makes that worse. Clean one small area with the soapy-cloth method, let it dry, and look again.

Chair arms, table edges and the fronts of drawers wear first. If the finish is gone in those spots, keep water off them until they are refinished, since bare wood soaks it up and darkens.

How to clean unfinished wood, veneer and wood paneling

Unfinished or raw wood

Bare wood has nothing between it and the dirt, so it absorbs water, oil and stains. Keep cleaning as dry as possible.

• Vacuum with a soft brush attachment, or dust with a dry microfiber cloth, working with the grain.
• Lift pencil marks and scuffs with a clean white eraser before reaching for water.
• For grime, use a cloth wrung out until it is barely damp with soapy water, work on a small area, and dry it at once.
• For marks that will not lift, sand lightly with fine sandpaper along the grain and vacuum the dust.
• Do not wipe oil or polish onto raw wood to “clean” it. Oil darkens bare wood and changes its color for good, and it makes any later stain or finish uneven.

Veneer

Much furniture is a thin layer of real wood glued over plywood or particleboard. You can often spot veneer at the edges, where a thin top layer or a band of edging covers a different core, or when the grain on a drawer front does not continue around the edge. Clean veneer like any finished wood, but keep water away from edges, seams and chips, where it can reach the glue and the core and lift or swell them. If veneer is already bubbled or loose, do not wet it; glue it back down or ask a restorer.

Wood paneling and wood walls

Dust paneling from the top down, then wash it in small sections with the same barely damp soapy cloth, following the grooves and grain, and dry each section before moving on. Work from the bottom up when washing so drips do not streak dry wood. Kitchen cabinets collect cooking grease and need more; see how to clean kitchen cabinets.

How to keep wood furniture clean longer

Most damage to wood furniture comes from water, heat, light and grit, not from a lack of polish.

• Use coasters, placemats and trivets, and wipe spills right away with a dry cloth.
• Lift lamps, vases and other objects to dust under them; dragging them grinds dust into the finish.
• Put felt pads under decorative objects and the feet of anything that sits on a wood surface.
• Keep furniture out of strong direct sun, which fades both wood and finish, and away from heaters, radiators and air vents, which dry it out.
• Rotate tablecloths, runners and decor now and then so one patch of the finish is not shaded while the rest fades.
• Dust weekly so you need to wash and polish far less often.

Why spray polish can make wood look worse

Many spray polishes leave silicone or wax behind, and layer after layer turns cloudy, sticky and smeary while attracting dust. That film can also make future refinishing harder.

Guardsman describes dust as wood furniture’s biggest enemy because it leaves microscopic scratches, recommends weekly dusting in the direction of the grain, and says its wood cleaner removes silicone and wax buildup left by some polishes. It also warns that excessive scrubbing and harsh cleaning agents can damage the gloss on even tough finishes. If you strip buildup with mineral spirits, ventilate: the EPA lists solvents and waxes among household products that release organic compounds indoors and advises using them with plenty of fresh air.

How to fix common marks after cleaning

White rings, dents and light scratches can often be fixed at home; deep burns and widespread finish damage need refinishing.

• White water rings and heat marks sit in the finish, not the wood. Howard Products says its Restor-A-Finish removes white heat rings and water marks, sun fade and oxidation without stripping the finish, followed by Feed-N-Wax to protect it. Our guide on how to remove water stains from wood covers more methods.
• Small dents in bare or lightly finished wood can be raised with steam. Minwax’s furniture first aid describes placing a damp cloth over the dent and heating it with an iron so the crushed fibers swell back.
• Light scratches can be hidden with a matching furniture touch-up marker or wax stick.
• A crackled, alligatored or flaking finish needs refinishing, which Minwax also covers.

Mistakes to avoid

• Using a wet cloth or spraying cleaner straight onto wood, so water seeps into joints and seams.
• Using all-purpose sprays, bleach or ammonia cleaners, which can dull or strip finishes.
• Polishing every week, which builds up a cloudy, sticky film.
• Wiping across the grain with a dirty or gritty cloth, which leaves fine scratches.
• Using vinegar or alcohol on shellac and antique finishes.
• Using a melamine sponge on wood, which acts like fine sandpaper.
• Rubbing oil or polish into unfinished wood, which darkens it permanently.
• Letting water sit on veneer edges and seams, where it can lift the veneer.
