How do I protect a wood table from scratches and heat marks?
Keep hot dishes and mugs off the bare top with trivets, hot pads or a padded tablecloth, and put felt or a placemat under anything that slides. Dust with a clean cotton cloth, never a feather duster. On a clear finish, thin paste wax adds a wear layer; the National Park Service puts rewaxing at every one to four years. Keep the table out of direct sun.

Step by step
Read when to stop and call a pro, further down this page, before you start.
Step 1: Find out what finish you have
Look at the top in raking light. A hard, glossy or satin film over the grain is a clear finish. If the wood looks raw, the finish is worn through, or you cannot tell what it is, skip the wax and ask a furniture repairer.
Step 2: Put a barrier under hot things
Use trivets or cork-backed hot pads under pots, serving dishes and coffee pots, and coasters under mugs and glasses. Make it a house habit so guests do not have to be told.
Step 3: Pad the table for daily use
Cover the top with a tablecloth over a felt-backed table pad for meals, homework and crafts, and use placemats with a soft backing for everyday eating.
Step 4: Add felt under objects that slide
Stick felt pads under lamps, vases, bowls and decor. Check them every few months, because grit trapped in worn felt scratches.
Step 6: Clean before you wax
Wipe off dust and grime so you do not seal dirt under new wax.[1]
Step 7: Apply paste wax sparingly
On a stable clear finish, rub on a thin coat of paste wax with a clean cotton cloth, wait an hour or two, then buff with another clean cloth. Two thin coats beat one thick one.[1]
Step 8: Move the table out of direct sun
Shade the windows or shift the table so sunlight does not fall on it all day.[1]
Step 9: Watch the humidity
Keep the room from swinging between very dry and very damp, with a target of about 50 percent relative humidity.[1]
Protect the top before it is damaged
A wood table stays good-looking when three things are true: nothing hot touches the bare top, nothing hard or gritty slides across it, and the finish is kept clean and waxed if it takes wax. All three are habits and cheap supplies, not repairs.
Start with what sits on the table. Put trivets or hot pads under pots, serving dishes and coffee pots, and coasters under mugs and glasses. For everyday meals, a tablecloth over a felt-backed table pad does the work of both, and placemats with a soft backing cover the rest. Stick felt under lamps, vases and bowls, and replace it when it wears thin, because grit trapped in old felt scratches like sandpaper.
Dust it the right way
Dust is a scratch risk as well as an eyesore. 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's advice for wood objects is to use a clean cotton cloth, and to turn the cloth frequently so that accumulated dust does not scratch the object's surface.[1] Wash the cloth after every use. Don't use feather dusters.[1]
Know your finish before you wax
Wax is the one product that adds a sacrificial layer. Wax helps protect the surface from abrasive dust and handling.[1] Waxing makes dusting easier.[1] It slows the penetration of water and water vapor, which will cause the wood to swell.[1]
But it only belongs on the right finish. Apply wax only to stable, clear finishes, such as shellac, varnish, and modern lacquer.[1] Wax applied to unfinished wood surfaces cannot be completely removed.[1] An older piece with an original wax finish is different: Do not clean a wax finish as you would a hard finish. Consult a conservator for advice.[1]
To wax, clean the top first so you do not seal in grime. Then rub on a thin coat of paste wax with a clean cotton cloth, wait an hour or two, and buff. It is preferable to apply two thin coats rather than a single thick coat.[1] Don't use paste wax made with strong solvents, such as xylene and toluene, because they can damage some finishes.[1] Don't apply wax when it is hot and humid. The wax may turn white and cloudy.[1]
How often? Most wood objects in furnished historic structures, however, will require rewaxing just every one to four years.[1] A handy test: rewaxing is not necessary if the existing wax layer can be buffed to a sheen.[1]
Mind the sun and the air
Sunlight does slow damage you will not notice until one side of the table has faded. Light causes deterioration of the cellular structure of wood, breaks down the lignin component, and bleaches its colors.[1] Light damage to wooden objects in furnished historic structures is most commonly caused by sunlight streaming through unshaded windows.[1] Not only is light harmful, but the heat it generates also does damage.[1] Shade the window, or move the table out of the beam.
Dry air hurts too. The ideal relative humidity level in most areas of the country for wooden objects is 50% plus or minus 5%.[1] Below 30% the glue may desiccate, joints may loosen, and finishes will become brittle.[1] A humidifier in a dry winter room helps, and so does keeping the table away from heating vents and radiators.
Stop and call a pro if
- A heat ring, white mark or scratch has gone through the finish into the wood. Wax will not repair it. A furniture repairer can touch up or refinish the top.
- The finish is peeling, sticky or cloudy across the whole top. The finish is failing, and wax over it only hides the problem.
- You are about to strip an older table. The EPA lists refinishing old furniture among the jobs that can put you in contact with lead.[2] Have a pro assess it before you sand.
- The table is an antique or family piece. Ask a conservator or experienced furniture repairer before waxing or cleaning anything.
- Joints, legs or the top are loose or cracked. That is a repair, not a protection problem.

Common questions
- Does a tablecloth protect a wood table from heat?
- A cloth alone is thin, so put a felt-backed table pad under it and still use trivets for hot pots and serving dishes. The pad cushions the top against scratches from plates and decor.
- Should I wax my wood table?
- Only if the finish is a clear film such as varnish or lacquer. The National Park Service says to apply wax only to stable, clear finishes, never to raw wood, and that most wood in furnished historic buildings needs rewaxing every one to four years. Skip it on an old table you suspect has an original wax finish and ask a conservator.
- Is a felt pad safe under a lamp or bowl?
- Yes, and it prevents most small scratches, but grit gets trapped in old felt and acts like sandpaper. Replace worn pads and lift objects instead of dragging them.
- How do I keep the sun from damaging my table?
- Move the table out of the direct beam or shade the window. The National Park Service says light bleaches wood color and breaks down the wood, and that unshaded windows are the usual cause of light damage in furnished historic homes.
- What if the table already has a heat mark or deep scratch?
- Protection will not remove an existing mark. A heat ring or gouge that has gone into the finish usually needs the finish repaired or the top refinished, and Loclis can match you with a local furniture repairer.
