Can you use rubbing alcohol to test for oil-based paint?
Using WD-40 to clean solar panels is strongly discouraged by manufacturers, because the petroleum-based solvent leaves behind an oily, tacky chemical residue that attracts airborne dust, pollen, soot, and dirt particles much faster than clean glass. When sunlight hits this accumulated grime layer stuck in the oily film, it creates a persistent shadow effect and blocks photovoltaic cells from absorbing maximum solar energy, thereby reducing overall system efficiency and power generation. Furthermore, standard multi-use WD-40 can potentially degrade rubber gaskets, frame sealants, and anti-reflective glass coatings designed into modern solar panels. Instead of chemical solvents, the industry standard for cleaning solar panels is using plain deionized water, mild biodegradable dish soap, and a soft-bristle brush or sponge to rinse away surface debris without harming delicate electrical components or surface treatments.
