Cleaning a plane at the end of the day give you a chance to perform something else that EVERY pilot should do regardless of the type of plane they fly, and that is inspect your plane. I can't even begin to count how many people I see just throw the plane in the car and head for home, and the next trip to the field they pull it out and fly without every inspecting it. Then when the plane crashes they can't figure out why. It's because they didn't find something that should have been repaired before they flew, and that broke and caused the plane to crash. When you spend the time to clean your planes at the end of the day take a few extra moments to inspect everything to see if it's still in good shape. Electric pilots should inspect their planes as all well.
