This is my second summer biking, last year was really just kind of getting to know my bike. I'm seriously considering commuting but...

What to do about cleaning up-from reading here I'm guessing wipes? We have no showers at the office.

What to do about my hair-Yikes! Scary!

What to do about keeping your working clothing looking halfway decent? When they told me it was casual here, I don't think the post-ride hot and sweaty look is what they meant.

In short, how do you bike to work and not look as though you did?

Thanks!
