Stone maintenance is mostly about consistency. Use a mild routine product that the stone supplier approves, remove spills rather than letting them sit, and avoid guessing with strong household chemicals.
Daily or routine cleaning
For routine dust and surface dirt, use a soft cloth or mop and a stone-safe cleaner appropriate for the exact material. Follow the product label and rinse according to its instructions.
Why acids are a problem
Acidic products can alter the surface of some calcareous stones. Marble is particularly vulnerable to etching from acids. Common household examples can include acidic descalers or acidic food residues. The safe approach is not to test a random chemical on a visible area.
What about sealing?
Sealing is not a universal “make the stone stain-proof” step. The correct product, surface condition and reapplication interval depend on the stone and finish. Ask the supplier or stone-care professional which treatment is appropriate.
When a stain appears
Do not immediately scrub harder. First identify whether the mark is a stain, etch, scratch, residue or moisture-related change. Different problems need different treatments, and aggressive abrasion can permanently change a finish.
Kitchen-specific reminder
Food oils, turmeric, coffee and acidic ingredients can interact differently with different surfaces. Wipe spills promptly and ask for the care sheet for the exact product installed.
