Quck answer
Cloudy plastic on solar light cells can reduce their efficiency. To clean it, start by removing the solar light cell from the fixture. Mix a solution of equal parts vinegar and water. Dip a soft cloth or sponge into the solution and gently scrub the cloudy plastic. Rinse the plastic with clean water and dry it thoroughly. If the cloudiness persists, try using a mild dish soap instead of vinegar. Avoid using abrasive cleaners or rough materials that can scratch the plastic. Regular cleaning will help maintain the performance of your solar light cells.
If your solar lights are not shining as brightly as before, the reason may be the cloudy plastic over the solar cell. Check if the plastic is cloudy or just dirty by wiping it off with a damp cloth. You can restore the clarity of the cloudy plastic by applying a coat of lacquer or nail polish.
Clean the Plastic First
If the plastic covering the solar cell appears white or cloudy instead of clear, clean it to identify whether the cloudiness is due to dirt and pollution buildup that can be removed or if the plastic remains cloudy even after cleaning.
Step 1
Remove loose dust and debris with a dry, soft cloth.
Step 2
Soak a cloth or sponge in slightly soapy water, squeeze out most of the moisture, and wipe the plastic again.
Step 3
Rinse the cloth or sponge and wipe the plastic again. Let the plastic air-dry or dry it with another cloth. If the plastic remains cloudy after drying, it needs additional treatment.
Reviving Cloudy Plastic
To restore the clarity of the plastic covering the solar cells, apply a thin layer of clear nail polish or spray-on clear lacquer. These clear coatings will make the plastic clear again. Cover the areas around the plastic, such as the cell housing or the light cover with a built-in solar panel, with painter’s tape before applying the chosen clear-coat material. Remove the tape once the coating dries.
