Natural stone flooring — marble, travertine, limestone, and slate — is common in Las Vegas homes, particularly in entry areas, bathrooms, and kitchens where the aesthetic suits desert architecture. Stone floors are durable and beautiful but require care that differs fundamentally from ceramic tile, hardwood, or vinyl. The governing rule: most natural stones are acid-sensitive, and the most common cleaning mistake — using acidic cleaners including vinegar — causes permanent surface damage that requires professional restoration to reverse.

The Acid Sensitivity Rule

Marble, travertine, and limestone are calcium carbonate — the same mineral that forms stalactites and seashells. Acids react with calcium carbonate and dissolve it, creating dull, rough etch marks on polished stone surfaces. This means no vinegar, no citrus cleaners, no bathroom tile sprays, no rust removers, and no acidic food spills left sitting (tomato, wine, citrus juice). Granite is silica-based rather than calcium-based, which makes it acid-resistant, but it’s still porous and requires sealing and careful care. When in doubt about any cleaning product’s suitability for your specific stone, test on a hidden area and look for any change in sheen or color before applying to visible surfaces.

Routine Cleaning

Sweep or dust mop stone floors daily to remove the fine desert dust that abrades polished surfaces when walked on — grit on a stone floor acts like sandpaper and gradually dulls polished surfaces over time. For wet cleaning, use a pH-neutral stone cleaner specifically formulated for natural stone — these are available at tile stores and home improvement centers. Never mop with plain water in Las Vegas — hard water leaves mineral deposits that dull stone finishes as they dry. Use a barely damp mop (not wet) and dry the floor quickly if residue is a concern.

Sealing

Sealing natural stone significantly reduces porosity, making stains and mineral deposits less likely to penetrate and making cleaning more effective. Use a penetrating impregnator sealer (not a topical coating sealer) specifically rated for your stone type. In Las Vegas conditions, reseal annually — the combination of foot traffic, cleaning, and the UV exposure near windows breaks down sealer faster than in moderate climates. Test whether resealing is needed: drop water on the stone and observe. If it beads up for 30 seconds or more, the sealer is adequate. If it’s absorbed within 15 seconds, reseal promptly.

Addressing Etch Marks and Damage

Light etch marks (small dull spots) on polished marble can sometimes be improved with a marble polishing powder and a soft cloth, following product instructions carefully. More significant etching, deep scratches, or extensive dullness requires professional stone restoration — a process involving honing with progressively finer diamond abrasives and then polishing to restore the original sheen. In Las Vegas, professional stone restoration services are available and represent a far less expensive option than floor replacement. After professional restoration, apply sealer promptly to protect the freshly exposed stone surface.
