To the contrary. When I cleaned my bike yesterday it was after a good 20+ mile ride. I use cleaning my bike as a cool down period, get the heart rate back under control, etc. Besides I come from the school that says a well maintained machine it a well running machine (that goes for the human body as well). Don't get me wrong. I am not a fanatic about it but when it needs it I tend to it. As for speed, it's not about speed for me but about a good work out and an ejoyable ride. I leave the speed to the rest of you.
