I had a mostly black Allez, and I never bothered to clean it unless it was REALLY grossly dirty. It didn't "look" dirty as easily as my Tarmac does... at least in my opinion... haha.
BarryJo, I am sure that "dirty" to me is nothing compared to your experiences, hehe. It's just that this bike is barely a month old, and is... shiny... and ... clean...

and I want it to stay clean, but I still want to ride it... haha
