Before you try anything: always speak to a professional before cleaning, treating or applying any product to your stone. Every slab is different, and the wrong product can cause permanent damage. Contact us or a qualified stone restorer first.
Quick answer
Most dark water rings on dolomite are just moisture that has soaked into the stone, and they fade as it dries over 24 to 72 hours. Keep the area uncovered with good airflow. White rings are mineral deposits, and pale, dull rings on polished stone are etches from the drink, and each needs a different fix.
First, check what you are dealing with
- Darker ring that looks damp: moisture in the stone. It usually dries out on its own.
- White, chalky ring you can feel with a fingernail: mineral deposit from hard water. See the hard water guide.
- Pale, dull ring on a polished surface: an etch from the drink, not water. See fixing etching.
What you need
- Clean dry cloth
- Fan or open window
- pH-neutral cleaner
Step by step
Identify the ring
Look closely: darker and damp-looking, white and chalky, or pale and dull. Each needs a different fix.
Let dark rings dry
Wipe the surface dry, remove anything covering it and let air move over it. Most dark rings on dolomite fade within one to three days.
Clean off white deposits
Soften mineral rings with warm water and pH-neutral cleaner, then lift them with a new plastic razor blade held flat.
Deal with what remains
A pale, dull ring that does not change is an etch. Light etches on polished stone can be buffed out with marble polishing powder; see the etching guide.
What not to use on dolomite
- Vinegar, lemon juice or "natural" citrus cleaners: they etch dolomite.
- Scourers, steel wool and abrasive creams on a polished surface.
- Mixing cleaning chemicals, especially bleach with anything else.
- Hairdryers or heat, which can drive minerals deeper.
- Descalers on acid-sensitive stone.
When to call a professional
Rings that persist after a week of drying and cleaning are worth showing a restorer. A restorer can re-polish dolomite, though it takes more work than marble because the stone is harder.
Understanding water rings and marks on dolomite
Dolomite is denser than marble but still moderately porous, so oil and dark liquids can stain it if they sit.
Dolomite is calcium magnesium carbonate. It reacts with acid more slowly than marble, but lemon, vinegar and acidic cleaners still etch it over minutes.

Good to know
Dolomite is dense enough that water marks usually dry out quickly. A ring that lasts is more likely a mineral deposit or a slow etch.
Stop it happening again
Whether yours is Super White and many stones sold as "soft quartzite", repairing it fixes today's mark; protecting it stops the next one. Our clear Stone Protection Film sits over the surface, so acids cannot etch it and liquids cannot soak in. Choose Gloss for polished dolomite or Matte/Satin for honed and matte finishes. The protection is identical. It is installed across Sydney with a 10-year written warranty.
