Granite loses its shine primarily through surface micro-scratches from daily use, abrasive cleaning products, and accumulated residue that dulls its reflective surface. Unlike softer stones, granite doesn't etch from acids — but it does scratch and dull over time. Professional diamond polishing removes these micro-abrasions and restores the original mirror finish. In some cases, failed or absent sealing has allowed oils to penetrate the stone, creating a cloudy appearance that requires stain extraction before polishing.

Granite is one of the hardest natural stones and is resistant to most everyday scratching. However, granite can be scratched by other granite, diamonds, or harder abrasives — including some cleaning pads and tools. Surface micro-scratches from years of use accumulate and visibly dull the stone's polish. Professional honing and re-polishing removes these fine scratches and restores granite's characteristic depth and brilliance.

Oil stains in granite require a poultice treatment — a drawing compound applied to the stained area that pulls the oil out of the stone's pores as it dries. DIY poultice kits are available, but professional treatments use stronger compounds and achieve more complete results, especially for older or deeper stains. NOVA Stone Care will assess the stain during your free evaluation and be transparent about what results are achievable.

For granite floors in high-traffic areas, professional polishing is recommended every 3–5 years. Granite countertops in active kitchens may benefit from professional cleaning and re-sealing every 1–2 years. Properly sealed and regularly maintained granite can go longer between full restorations.

Most granite does benefit from sealing, though granite varies significantly in porosity. Denser, darker granites may absorb very little, while lighter, more porous varieties can stain easily without proper sealing. A simple water test reveals whether your granite needs sealing: if water beads on the surface, the seal is still effective; if water is absorbed, it's time to re-seal. We test your specific granite during the free assessment.

Yes — we restore exterior granite surfaces including steps, paving, pool surrounds, and outdoor countertops throughout Northern Virginia and Maryland. Exterior granite faces additional challenges from weathering, biological growth, and exposure, which our technicians are fully equipped to address.

Use a pH-neutral stone cleaner for daily wiping — never abrasive scrubbers, acidic cleaners, or harsh degreasers. Wipe spills promptly, especially oils. Use cutting boards and avoid dragging cookware. Re-seal every 1–3 years depending on use and porosity. We provide a complete care guide after every restoration project.
