Daily Maintenance and Renovation of Granite

Granite floors, while known for their durability (Mohs hardness of 6-7) and relatively strong resistance to acids and alkalis compared to marble, still face common issues in daily maintenance due to their material properties and usage environments:

1.Surface gloss wear and micro-scratches

Though granite is hard, long-term friction from high foot traffic, dragging of hard objects (e.g., furniture without protective pads, metal debris), or frequent contact with abrasive particles (e.g., sand tracked in by shoes) can gradually wear down its polished surface. Over time, this leads to a dull, lackluster appearance, with visible micro-scratches that disrupt the original mirror-like finish.

2.Stain penetration (especially oil-based or deep-colored stains)

While granite has a denser structure than marble, it is not entirely non-porous. If oil, soy sauce, wine, or other viscous/colored liquids spill and are not cleaned promptly, they can seep into the micro-pores on the surface. Once absorbed, these stains (especially dark stains on light-colored granite) are difficult to remove completely, leaving stubborn discoloration.

3.Acid corrosion (localized damage)

Though more acid-resistant than marble, granite is not impervious to strong acids. Long-term exposure to concentrated acids (e.g., hydrochloric acid, battery fluid, or even excessive citrus/juice residues) can react with minerals in the stone, causing localized etching. This appears as dull, matte patches or tiny pitting on the surface, irreversibly damaging the polished layer.

4.Joint issues

Poor-quality or aging grout in the joints between granite tiles allows moisture, dirt, or even mold to infiltrate the substrate. This can lead to water damage beneath the floor, loosening of tiles, or unsightly black mold growth in the joints. Additionally, long-term friction at joints may cause chipping or unevenness at the edges of adjacent tiles.

5.Improper maintenance damage

• Using abrasive tools (e.g., steel wool, wire brushes) or harsh detergents (with strong alkalis or abrasives) for cleaning can scratch or corrode the surface, accelerating wear.
• Neglecting regular protective treatments (e.g., applying stone sealers) reduces the floor’s stain and water resistance, making it more susceptible to penetration by liquids and contaminants.
• Over-polishing with improper polishing agents (e.g., those containing excessive acidic components) may erode the surface layer, weakening its durability over time.

6.Water-related issues (mold or efflorescence in humid environments)

In persistently humid areas (e.g., bathrooms, kitchens), prolonged moisture accumulation (from incomplete drying after cleaning or leaks) can seep into joints or micro-pores. This may lead to mold growth on the surface or in gaps, or in rare cases, efflorescence (white powdery deposits) if water carries soluble salts from the substrate to the surface as it evaporates.

To address these problems, we have designed targeted solutions.

Deep Cleaning and Care for Granite

Tools and Materials :

SC Swift Deep Floor Cleanser, Blue Shield, crystallizing machine, 3M red pad, 3M white pad, dust mop.

Operation Process:

1.Clean the granite floor using SC Swift Deep Floor Cleanser (a weakly alkaline cleaning powder that won’t damage the granite), a crystallizing machine, and a red pad.

2.Use an automatic floor scrubber to thoroughly rinse the floor with water, remove the moisture, and let it dry.

3.Spray Blue Shield on the floor (5-10 ml per square meter), use a 3M white pad, and match it with a crystallizing machine.

4.Grind Blue Shield evenly until dry (takes about 2-3 minutes), and a hard crystal shield protective film will form on the floor.

5.If there is dust on the floor, clean it with a dust mop and repeat the operation with Blue Shield once more. This will make the Blue Shield protective film stronger and brighter.
