The product is resistant to damp air and splashes during

concrete or brick which can contain salt, you must flush
the product after the work. The cleaning reduces the risk
of accretions inside the engine. The accretions inside
the engine can cause leakage current between electric
components. The leakage current can cause the ground
fault circuit interrupter to trip accidentally.
