Marble

Marble is a carbonate stone, so acid contact can create actual finish damage. Treat marble as more acid-sensitive than granite and materially different from quartz.

• Quartz is engineered and resin-sensitive; granite is natural stone plus sealer; marble is acid-reactive and more prone to visible etching.
• A quartz-safe or granite-safe cleaner should not be assumed marble-safe unless the label explicitly covers marble.

• Polished marble shows etching and wipe marks quickly under side light.
• Honed marble hides glare but can absorb oils and pigments more readily when the sealer is weak.

• Scrubbing cannot remove chemical etching; it usually broadens the dull area.
• Powders, pads, honing, and polishing belong to restoration, not routine cleaning.

• Dull splash-shaped marks often indicate etching.
• Dark wet-looking spots indicate absorption or sealer weakness.
• Circular glass rings can be etching, mineral residue, or absorption and should be diagnosed before cleaning strength increases.

• Blot acidic and pigmented spills immediately.
• Use neutral cleaning regularly and keep water from lingering at vanity or countertop edges.
• Review sealer performance and finish condition before stain work or polishing.
• Treat every unknown marble finish as acid-sensitive and abrasion-sensitive.
• Stop when dullness remains after neutral residue removal; the next step is stone assessment, not stronger household chemistry.

• Hospitality, bath vanity, and high-end kitchen marble need a stop-before-damage protocol because visible etching can happen quickly.
• Professionals separate cleaning, poulticing, honing, polishing, and sealing into different scopes.

• Neutral marble-safe cleaning is compatible with routine soil and light residue.
• Acidic mineral removers, vinegar, citrus cleaners, and generic bathroom descalers are avoid lanes for marble.
• Poultices, powders, honing, and polishing are professional or label-directed restoration lanes, not general maintenance compatibility.
