How to clean natural stone without taking unnecessary risks

01

Why natural stone needs its own care plan

Stone may be honed, polished, textured or treated with an impregnating or topical product. A method that appears successful on one worktop can dull another. Calcareous stones such as marble, limestone and travertine are particularly vulnerable to acidic substances, including common household ingredients such as vinegar and lemon juice.

Sealing can reduce the rate at which some liquids enter the stone, but it does not make every surface stain-proof or resistant to acids and scratches. Keep the installer, fabricator or stone supplier's product information with the household care notes and make sure anyone cleaning the home can find it.

02

A cautious everyday routine

Remove loose grit before wiping because particles dragged across a polished floor or worktop can mark it. Use clean, non-abrasive tools and a product confirmed as suitable for that particular stone and finish. More detergent does not mean a better result; excess product can leave residue and make a surface appear smeared.

• Blot spills promptly rather than spreading them across the surface
• Lift loose particles with a soft method before damp cleaning
• Use the stone supplier's recommended cleaner and dilution
• Keep cloths, mop heads and water clean throughout the task
• Dry or buff only where the care instructions recommend it
• Use mats, coasters and trivets as appropriate to the room and finish

03

Products and tools to approach with care

Do not use vinegar, lemon-based mixtures or general acidic limescale remover on marble, limestone or travertine. Abrasive powders, rough pads and blades can scratch or alter a finish. Strongly alkaline products may also be unsuitable for the stone, sealer or surrounding materials. A label saying natural does not make a product appropriate.

Where the exact material or coating is unknown, use no experimental mixture. Ask the installer or an experienced stone-care professional to identify it. Always test an approved method in a discreet place and inspect the result after it has dried.

04

A stain is different from an etch mark

A stain is discolouration caused by something entering or bonding with the stone. Etching is a change to the surface itself, often seen as a dull or lighter patch where an acid has reacted with a calcareous stone. Ordinary cleaning cannot polish an etched surface back to its original finish.

If a mark remains after appropriate routine care, avoid escalating through stronger products. Photograph it, record what caused it if known and seek advice from the supplier or a stone-restoration specialist. Early, accurate information is more helpful than repeated treatment.

05

Bathrooms and hard-water deposits

Stone bathrooms need a plan that respects both water deposits and acid sensitivity. The limescale remover commonly used on ceramic or glass may damage adjacent marble or limestone. Daily control—removing standing water where practical, ventilating the room and using the approved maintenance product—is safer than allowing deposits to build and then attempting aggressive removal.

Check junctions carefully. A glass screen, metal fitting and stone ledge may sit within centimetres of each other but require different products. Apply products to the cleaning cloth where appropriate and avoid uncontrolled spray onto neighbouring finishes.

06

When to call a stone specialist

Deep staining, widespread etching, scratched polished surfaces, failing sealers and cracked or loose stone are not routine housekeeping problems. A specialist can identify whether honing, polishing, poulticing, repair or resealing is appropriate. The cleaning team's role is to maintain sound finishes and notice changes early, not to disguise damage with stronger chemistry.
