  1. Wash the onyx with warm water and mild soap

    Wet a cloth in warm water, apply a dot of liquid soap and wipe the onyx. This removes surface dirt, dust and chemical residue. Immerse the cloth in warm water and wipe the onyx to remove lingering soap.

  2. Dry the onyx with a soft towel

    Wipe the onyx thoroughly with a soft, dry towel. Buff it until it is completely dry.

  3. Apply stone cleaner

    Squeeze a dot of stone cleaner onto a clean cloth and rub it over the onyx for five minutes. The cleaner seals the onyx and protects it from grime. Let the cleaner dry for another five minutes, then polish the onyx with a soft, clean cloth. Buff it for 10 minutes using small circular motions.

  4. Rest the onyx for six hours

    Let the freshly buffed onyx rest for at least six hours before touching it with bare hands or getting it wet.
