the many textures of carwash clean

I took my car to a drive-through car wash last week. It's so dusty around USC, and plus I park under a tree that insists on dripping sap and tiny twigs and even tinier leaves onto my poor car, so after two weeks it's usually in need of a wash, and well, I neglected cleaning it for a month so it was filthy. I happened to have my camera with me as I sat through the motions of the car wash and snapped away while enjoying the drenching, rumbling, whupping, whooshing and whirring of the car wash.
