One thing that I cannot recommend highly enough is one of those sweat shields that attaches to your handlebars and seatpost, AND towels. Riding outside on hot days, I will often find a line of crusty salt underneath the top tube from sweat. And that's a lot of it evaporating off me. Using a sweat shield, plus a towel over the bars, plus another towel for mopping my face, I find the top tube doesn't even get anything on it.
