TL;DR
A white ring on a wood coffee table is moisture trapped in the finish, not a stain in the wood, and a fresh one can often be drawn out with gentle heat or a light abrasive. A dark ring is a different problem -- moisture has reached the wood itself, and that usually needs refinishing rather than cleaning.
What a coffee table actually collects
A coffee table sits at the centre of the busiest room in the house and takes a soil mix no other furniture gets.
Drink rings and condensation from cold glasses. Food debris and grease transferred from hands and plates. Skin oil, which builds into a slightly tacky film on the areas people rest their feet or elbows. Remote controls, laptops, and phones, all of which leave contact marks. And the ordinary settling dust that any horizontal surface gets.
That combination is why a dry dust cloth stops being enough on a coffee table long before it stops being enough on a bookshelf. Oil and sugar residue need a damp pass and a moment of contact.
Identify the finish before anything else
Every recommendation below depends on knowing what you have, and getting it wrong is what turns a cleaning job into a refinishing job.
Sealed or lacquered wood has a hard clear film over the timber. Water beads rather than soaking in. This is most modern furniture and it is the most forgiving.
Oiled or waxed wood has no film; the protection is in the surface of the timber. Water darkens it and detergents strip it. It needs re-oiling on its own schedule -- see oiled versus waxed wood furniture care.
Antique or French-polished surfaces are shellac based and are damaged by water and by alcohol. Treat as dry-dust-only and get specialist advice before anything wet.
Glass, stone, and metal tops each have their own rules, and the stone one is the strictest.
The routine clean
Dust first with a dry or barely damp microfibre cloth. Then, for the residue a dry cloth leaves behind, use a cloth wrung out in a very mild solution of dish soap and warm water, followed immediately by a dry cloth.
Wipe with the grain on wood. Do the edges and the underside lip of the top, which collect more hand contact than the surface does. Then the legs, which are almost never included.
Skip polish on a sealed table. It sits on top of the finish, attracts dust, and hazes into a film that eventually needs removing. The reasoning is in whether furniture polish builds up on wood.
What is the white ring on my coffee table?
A white or cloudy ring is moisture that has penetrated the finish layer but not the wood. The clouding is light scattering off trapped moisture, which is why the mark disappears if the moisture can be driven back out.
That is good news, because it means a fresh white ring on a sealed finish is often reversible.
The gentlest approaches first, testing in an inconspicuous spot every time:
Gentle dry heat. Lay a clean, dry cotton cloth over the ring and pass a warm -- not hot -- iron over it in short bursts of a few seconds, checking after each. The heat encourages the trapped moisture to leave. Never let the iron sit, and never use steam.
A very mild abrasive. A small amount of non-gel white toothpaste, or a paste of baking soda and a little water, rubbed very gently with the grain on a soft cloth. This works by polishing the top microns of the finish, so use minimal pressure and stop as soon as the mark lifts. Buff and wax or oil afterward if the finish calls for it.
Do not use these on oiled, waxed, or shellac finishes without advice. On those, an abrasive removes finish rather than polishing it.
When it is a dark ring
A dark or black ring means moisture went through the finish and reached the wood, where it has reacted with tannins in the timber or supported mold growth.
Cleaning will not remove it, and the mild abrasive approaches above will not either, because the mark is below the finish rather than in it.
The honest answer is that a dark ring is a refinishing job: the finish has to come off the affected area, the wood is treated or bleached, and the finish is rebuilt. That is a job worth taking to a furniture restorer on anything valuable.
The wider set of avoidable errors is in the mistakes that ruin a wood furniture finish.
Other tops, briefly
Glass. Streak-free cleaner sprayed onto the cloth, then a dry buff. Do the underside as well, since a glass top shows both surfaces.
Marble, travertine, or limestone. pH-neutral cleaner only. Vinegar, lemon, and citrus cleaners permanently etch these stones, leaving a dull mark that is a change to the stone itself rather than a stain. Seal a stone top on the schedule its supplier recommends.
Laminate. Damp cloth, mild detergent, and keep moisture off the seams and edges where the core is exposed.
The habit that prevents most of it
Coasters, and a cloth kept within reach of the room.
Rings form because condensation sits for twenty minutes, not because a glass touched the wood. A drink lifted and wiped immediately leaves nothing behind. This is the rare cleaning problem where prevention is genuinely trivial and the cure is genuinely difficult.
A tray for the objects that live on the table -- remotes, coasters, a candle -- means the surface can be wiped in one motion rather than around a dozen items. And a thirty second wipe at the end of each evening is what stops the tacky film from ever forming. The general finish-safe method is in how to clean sealed wood furniture.
FAQ
How do you get a white ring off a wood table?
A white ring is trapped moisture in the finish, not a stain in the wood. Gentle dry heat through a cloth, or a very mild abrasive such as non-gel toothpaste rubbed lightly with the grain, will often draw it out. Test in a hidden spot first.
Why is my water ring dark instead of white?
Because moisture went through the finish and reached the wood itself, reacting with tannins or supporting growth. Dark rings are below the finish, so cleaning cannot reach them. Removing one means refinishing the affected area, which is a restorer's job on a valuable piece.
What should you clean a wood coffee table with?
A barely damp microfibre cloth for dust, and a cloth wrung out in a very mild dish soap solution for residue, always followed immediately by a dry cloth. Wipe with the grain, spray the cloth rather than the table, and skip polish on a sealed finish.
Can you use vinegar on a wood coffee table?
It is not recommended. Vinegar dulls polyurethane over time, and on a stone top it etches permanently. Plain water on a well-wrung cloth, or a very mild detergent solution, cleans a table better and without the risk.
Why does my coffee table feel sticky?
Usually a film of skin oil and food residue, sometimes combined with old polish buildup. A cloth wrung out in mild dish soap solution, followed by a plain water wipe and a dry buff, removes it. Stop using polish if that is the source.
How do you protect a coffee table from rings?
Coasters, and wiping condensation as soon as a glass is lifted. Rings form from moisture sitting for minutes, not from momentary contact. A tray for the objects that live on the table also makes the surface easy to wipe in one motion.
