How to Clean Solar Garden Lights

Victoria Lee Blackstone

Keep solar garden lights and their solar panels clean so they can perform optimally to keep your garden lit at night.

Use solar garden lights to light paths and structures to create whispers of brightness throughout your garden at night, creating a mood or making the garden safer to walk through. Solar garden light fixtures are only as good as the light they produce, which is diminished if the lights or solar panels are dirty. Clean the lights so you get the most from them.

Solar garden lights are typically low-maintenance, easy-to-clean fixtures. They line paths, provide spot lighting or sit atop patio tables. Regardless of their shape or function, they're exposed to the elements. Their mini solar panels can become soiled from numerous sources, including garden soil that splashes onto them during heavy rains, dust, calcium deposits from water, bird droppings and pollen grains.

Cleaning Solar Lights

Clean the panels whenever they look dirty. Check them after heavy rains or at least once every few months.

  1. Use a soft cloth or sponge to brush debris from the solar panels.

  2. Dampen a soft cloth or sponge with water and use a non-abrasive soap to clean the solar lights. Do not press or scrub the light. Use a gentle wiping motion.

  3. Remove all soap residue by wiping the solar lights with a soft, damp cloth or sponge after cleaning them.


Research scientists have taken a cue from how plants harness, store and use solar energy to develop more energy-efficient, long-term storage of solar energy in panels.


Don't use solvents to clean the solar panels.
