Maintenance Tips
  • Regular dusting: Use a soft, dry microfiber cloth to keep aluminum surfaces and glass shades clean and dust-free.
  • Gentle cleaning: Wipe with a soft cloth dampened in lukewarm water and mild detergent for fingerprints or light stains; dry immediately.
  • Avoid abrasives: Do not use polish, scouring pads, alcohol, or ammonia-based cleaners as they can damage the anodized aluminum finish.
  • Glass care: Clean opal glass shades only when cool to maintain even light diffusion and avoid thermal stress.
  • No moisture exposure: Prevent water from entering lamp joints, socket area, or electrical components.
  • Bulb safety: Always switch off and unplug before cleaning or replacing the light source.
  • Finish protection: Avoid prolonged contact with greasy or acidic substances that may stain aluminum.
  • Stable placement: Periodically check base stability to prevent tipping or vibration wear on joints
