1:45 is a pretty long commute - mine is about 45min, so that may very well make a big difference. I start off clean, then when I get to work, I cool down 15-20min and then wipe down. When it gets hotter, I will probably resort to a "sink bath" with a wet cloth. SO far, I havent had any perceptible issues with feeling dirty or smelling. Its a lot less of an issue than most people think it will be. The key is starting off fresh and clean before the ride.
