A shop that washes off your bike as a courtesy? Wow! That sounds like a place I'd love to have around here.
But don't
I always clean mine before I take it into the shop so I'm not embarrased by having a dirty bike. They've actually thanked me for it, saying how much easier it is to work on. Besides, I really try to keep my babies clean........ everything not only looks better but runs better and last longer. I don't know that I'd trust anyone else to clean them as carefully as I do...... Am I paranoid, or what???
