Clean a marble table with warm water and a few drops of pH-neutral washing-up liquid, then dry it with a soft cloth. That is the entire routine, and anything stronger is a risk rather than an upgrade. What actually protects a marble table is what you keep away from it: vinegar, lemon, bleach, glass cleaner and bathroom descalers all damage the surface, most of them on contact. Marble is calcium carbonate, so acid does not stain it — it dissolves the polish, leaving a dull mark that no cleaning will remove.
Why marble needs different treatment
Marble is calcium carbonate. Acid dissolves calcium carbonate, and that reaction does not need the acid to soak in — it happens the moment the liquid touches the polished surface. This is why marble behaves so differently from granite or quartz, and why the fix for a dull mark is not a stronger cleaner.
The daily routine
Stain or etch — the difference that decides everything
| Stain | Etch | |
|---|---|---|
| What it is | A substance absorbed into the stone’s pores. | Acid has corroded the polished surface itself. |
| How it looks | Darker than the surrounding marble. | Lighter, duller or chalky — sometimes only visible at an angle. |
| Usual causes | oil, coffee, wine, grease, ink, rust from metal | lemon, vinegar, wine, tomato, fizzy drinks, many household cleaners |
| The fix | Draw it back out with a poultice. | Re-polish with marble polishing powder. Deep etches need a professional. |
| Prevented by | Sealing. A sealer slows absorption, buying you time to wipe. | Nothing you apply. Only keeping acid off the surface — a sealer does not prevent etching. |
The safe routine
- Wipe spills as they happen — especially anything acidic.
- Clean with warm water and a few drops of pH-neutral washing-up liquid, or a cleaner sold specifically for natural stone.
- Dry with a soft cloth rather than letting it air-dry, to avoid water marks.
- Use coasters under glasses and boards under anything hot or oily. Trivets matter less for heat damage than for what is usually on the pan.
What to keep away from marble
| Never use | What it does |
|---|---|
| Vinegar | Acidic — etches on contact. |
| Lemon juice | Acidic — etches on contact. |
| Bleach | Can dull the polish and discolour some marbles. |
| Ammonia and most glass cleaners | Alkaline enough to damage the finish over time. |
| Bathroom or tile descalers | Formulated to dissolve limescale — which is chemically close to what marble is made of. |
| Abrasive powders and scouring pads | Scratch the polish. |
| Magic-eraser style melamine pads | Micro-abrasive; they dull polished marble. |
Marble damage, diagnosed
| What you are seeing | What it actually is | What to do |
|---|---|---|
| A dull, lighter patch | Etch — acid corroded the polish | Marble polishing powder. Cleaning will not touch it. |
| A dark mark that will not wipe off | Stain — something absorbed into the pores | Poultice, 24–48 hours, repeat as needed. |
| A ring where a glass stood | Usually an etch from the drink, sometimes hard-water minerals | Wet it: if it vanishes while wet, it is an etch. |
| Cloudy film across the whole surface | Soap residue or hard water, not damage | Rinse with clean water and buff dry. |
| A fine scratch you can feel | Physical abrasion — marble is soft | Polishing powder if light; a professional if you can catch a nail in it. |
| Yellowing over a large area | Often iron in the stone oxidising, or old sealer breaking down | This one is a professional job — DIY attempts usually worsen it. |
| A crack or chip | Impact or thermal shock | Professional. Epoxy repairs are colour-matched by eye and hard to do well. |
When to stop and call a professional
- The etch or scratch is deep enough to catch a fingernail.
- The damage covers a large area rather than one spot — patch-polishing a wide area leaves visible bright spots.
- The marble is honed and you want the mark gone. Polishing powder puts a shine where there was none.
- There is yellowing, cracking or chipping.
- The table is antique or the slab is thin — both raise the cost of a mistake well above the cost of advice.
Frequently asked questions
Can I use washing-up liquid on marble?
Yes, a few drops in warm water is the standard recommendation, provided it is pH-neutral. Avoid anything marketed as degreasing or descaling.
Are marble-branded cleaning sprays worth it?
They are convenient and safe, but they do nothing warm water and neutral soap cannot. Buy one if you want the convenience, not because the table requires it.
Why does my marble look cloudy after cleaning?
Usually soap residue or hard-water minerals left to air-dry. Rinse with clean water and buff dry. If the cloudiness is in one patch and will not wipe away, it is an etch, not a film.
