I work next door to a carwash. They seem to do a pretty good job on everything that goes through. But there are lots of customers who go over their cars looking for water drops leftover and having the crew come remove them. All carwashes (that I've ever known of) here in so cal use de-ionized water for the final rinse. They have for decades. So why is it that these certain customers insist on having every drop of water removed? Is it pure ignorance of a common know fact or something else?
