Why Clean Solar Lights

Solar lights can collect dust and grime as time passes. They gather on the panels, blocking the sunlight from reaching the solar panel. So the light will be dimmed. In addition, the dirt will eventually cause rusting in the metal components of your solar panel. These factors are completely unavoidable. Hence, you should clean your solar panels. It allows you to check for any problems earlier on.

Tools of Clear Solar Lights

Sandpaper or a soft bristle brush

Solar panels may have some accumulated debris and dirt. So, we use sandpaper or a soft bristle brush to scrub off any stubborn dirt on your solar lights.

Dish Soap

We need a detergent to help us loosen the dirt so it can be wiped off easily.

Painting tape.

Cover the plastic part of the light with painting tape. Don’t use sticky tape like duct or packing tape. This will be difficult to remove and will leave sticky residue behind.

Cloth or towel

You can damp cloth to remove loose dirt or clean off the residue soap. After cleaning, you can use a dry cloth or towel to completely dry out the lights.

Clear coat spray

A clear coat spray is a transparent paint to protect it from damage and UV rays. It also gives a glossy finish that deepens the base color quality and lets you easily buff out scratches. So, we use this spray to make our solar cells bright as they used to be.

Step By Step Guide to Clean Solar Lights
