Owning a handmade onyx chess set or any premium marble decor is a privilege, but it also comes with the responsibility of proper maintenance. Because natural stone is porous, it requires specific care routines to prevent staining, etching, or losing its high-gloss polish.
Understanding Onyx and Marble
Both onyx and marble are calcium-carbonate-based stones. This means they are highly sensitive to acidic substances. A spill of wine, citrus juice, or even the use of standard household cleaners containing vinegar or bleach can permanently etch the surface, leaving dull, unpolishable spots on your luxury items.
Step-by-Step Cleaning Guide
- Dust Regularly: Use a soft, dry microfiber cloth to gently wipe away dust from the chess board and individual pieces.
- Use a Damp Cloth: For light smudges or fingerprints, slightly dampen the microfiber cloth with warm water and gently wipe the surface. Dry immediately with a separate cloth.
- Avoid Harsh Chemicals: Never use abrasive sponges or acidic cleaners. If necessary, use a few drops of a pH-neutral stone cleaner diluted in water.
- Handle with Care: While marble is heavy, it can chip if dropped or knocked against hard surfaces. Always lift the chess pieces carefully rather than dragging them across the board to prevent micro-scratches.
Long-Term Preservation
For long-term preservation of your luxury marble decor items, consider applying a natural stone sealant once a year. This creates a protective barrier that repels liquids and prevents staining. Keep your onyx pieces out of direct, prolonged sunlight, as extreme UV exposure can sometimes alter the natural coloration of the stone over many years.
