Keep your glowing pendulum swinging cleanly and safely. Follow these simple care and display steps to protect the finish, the LEDs, and your desk.

Quick answer

Dust the frame and balls weekly with a dry microfiber cloth, keep the pendulum on a stable, dry surface away from direct sun, and handle the glowing base gently to protect the LED illumination. Always lift the unit by the base, not the swinging balls.

Why the LED base changes your cleaning routine

The Luminous Newton's Pendulum adds LED illumination to the classic cradle, so the base contains electronic components that should never be submerged or sprayed directly. Unlike a plain metal cradle, you cannot simply rinse or wipe the whole unit with a damp cloth. Instead, treat the base as you would any small electronic device: keep it dry, dust it with a soft dry cloth, and avoid harsh cleaners that could cloud the clear parts or damage the finish. The swinging balls and frame still need regular dusting to keep momentum smooth, but the glowing element means you should always check that the unit is switched off before cleaning.

Step-by-step care and display routine

Set up on a stable, dry surface: Place the pendulum on a level desk or shelf away from direct sunlight, heat sources, and areas with high humidity. Avoid placing it near open windows or vents where dust and moisture can accumulate. A wobbling or damp surface can cause the balls to swing unevenly and may stress the base over time.
Dust the frame and balls weekly: Use a dry microfiber cloth or a soft brush to gently wipe the metal frame and each ball. Work from top to bottom so dust does not fall onto clean parts. Do not use water or cleaning sprays on the balls or frame. Skipping weekly dusting lets grit build up, which can dull the finish and interfere with smooth swinging.
Clean the LED base carefully: Switch off and unplug the unit if applicable. Wipe the base with a dry or very slightly damp cloth, then dry immediately with a soft towel. Never spray liquid directly onto the base or allow moisture near any openings. Even a small amount of moisture inside the base can damage the electronics and stop the glow.
Check and adjust ball alignment: After cleaning, gently lift each ball and let it hang freely. Make sure all balls are level and not touching each other at rest. If one ball hangs lower, gently adjust the string or frame according to the manufacturer's instructions. Misaligned balls reduce swing efficiency and can cause the pendulum to stop early.
Handle with care during moves: When relocating the pendulum, always lift it by the base with both hands. Do not carry it by the frame or let the balls swing while moving. Place it back on a stable surface before releasing. Carrying by the frame can bend the wires or detach the balls, and swinging during transport may scratch the finish.
Store safely when not in use: If you need to store the pendulum, remove the batteries if applicable, wrap the base in a soft cloth, and keep the unit in a dry place. Avoid stacking heavy items on top. Leaving batteries in during long storage can cause leakage and permanent damage.
