Marble is primarily composed of natural calcium carbonate, making its surface sensitive to chemical etching from common household liquids. Protecting your investment requires setting clean daily care protocols and understanding the chemical difference between surface staining and physical etching.

• Understanding Etching vs. Staining:
  • Chemical Etching: Acidic substances (lemon juice, wine, vinegar, harsh bathroom cleaners) react instantly with calcite, dissolving the polish and leaving dull, pale spots. Etching is a surface corrosion issue, not a stain.
     
  • Organic Staining: Oil, coffee, or wine penetrating unsealed micro-pores creates a dark spot beneath the surface. Stains occur when liquids sit on unsealed stone over extended periods.

• Daily Maintenance & Cleaning Protocols:
  • pH-Neutral Cleaners: Wash marble surfaces using dedicated pH-neutral stone cleaners (pH 7 to 8) and soft microfiber cloths. Avoid acidic cleaners, bleach, ammonia, or abrasive scrubbing pads.
     
  • Immediate Blotting: Blot accidental spills immediately with an absorbent towel—never wipe, as wiping spreads the liquid across a larger area.

• Periodic Sealing & Professional Restoration:
  • The Water-Drop Test: Pour a few drops of clean water onto your stone surface. If the water beads up after 15 minutes, your sealer is active. If the stone darkens, it is absorbing water and requires immediate resealing.
  • Resealing Schedule: Reapply a breathable, impregnating fluoropolymer sealer every 12 to 18 months in residential applications.
  • Restoration: Light surface etching can be restored using specialized diamond-impregnated polishing compounds or by hiring professional stone conservators.
