Maintenance & Care Guidelines
Natural granite is low-maintenance-but proper handling ensures lifelong performance:
- Clean regularly with pH-neutral cleaners; avoid acids or abrasives.
- Wipe dry after use to prevent water spotting (though our granite has <0.3% porosity).
- Avoid direct impact-while highly rigid, granite is brittle under point loads.
- Store in stable temperature/humidity (ideal: 20±0.5°C, 50% RH).
- Recertify flatness annually in high-precision environments using a calibrated surface plate or laser tracker.
