How to Clean and Care for an Onyx Lamp

The simplest care routine is usually the most useful: remove dust gently, keep the lamp dry around its electrical components and avoid products that can damage the finish. An onyx lamp is both a stone object and an electrical assembly, so cleaning should respect both parts.

These guidelines are a starting point for pieces made by Vilona family artisans. Follow any specific instructions supplied with your lamp, particularly if it has a special finish, repaired area or a different lighting system.

Begin with the lamp switched off

Switch off and unplug a plug-in lamp before cleaning, and allow its light source to cool. For hardwired equipment, follow the supplied maintenance instructions and use a qualified professional when isolation or access is uncertain. Do not open a live electrical assembly to reach a mark or remove dust.

Start with a clean, soft, dry cloth. Remove loose grit gently instead of pressing it into the surface. If a mark remains, ask whether a lightly dampened cloth or a compatible pH-neutral stone cleaner is appropriate for the exact finish. Apply moisture to the cloth sparingly, not directly into the lamp, and dry the stone afterward.

Avoid aggressive cleaning methods

Decorative onyx can be sensitive to acids. Avoid vinegar, lemon-based cleaners, abrasive pads and unapproved polishing compounds. Do not immerse a lamp, wash it under running water or use steam around its components. A stronger product is not automatically a better solution for a stubborn mark.

Keep an unfamiliar product off the visible surface until its compatibility has been confirmed. If the lamp has a protective treatment, follow the treatment maker’s care instructions as well as the stone guidance. Do not add wax, oil or sealer as a routine step without knowing what is already on the piece.

Distinguish a stain from a change in the surface

A dull patch, a darkened area and a visible line may have different causes. More scrubbing can make the problem harder to assess. Photograph the area in normal light and describe what contacted it, when the change appeared and which products have been used. Send that information to our family before attempting a repair.

Natural mineral lines and openings should be compared with the original photographs where available. A new crack, loose component or unstable base needs attention; stop using or moving the piece unnecessarily until it has been assessed.

Move the lamp with its weight supported

• Unplug it and clear the route before lifting.
• Support the body or base according to the piece’s handling instructions.
• Do not lift by the rim, cord, socket or decorative projection.
• Use appropriate help for a large or heavy lamp.
• Place it fully on a stable surface and keep the cord out of walking routes.

Keep lighting changes specific to the lamp

Use the correct replacement bulb or component for the actual socket, power rating, enclosure and control system. If dimming or a remote stops working as expected, record the component details and ask for help. Avoid experimenting with incompatible dimmers or higher-wattage sources.

Keep the order information and original photographs with the care instructions. They make it easier to identify the piece and its configuration if a question comes up later. A little preparation and a gentle routine help preserve the appearance you chose without introducing unnecessary treatments.
