It worked for me in DC, where it's humid to boot. I've also heard people suggest baby wipes, but who knows what works for whom? I had a coworker who would come in drenched in sweat after walking two miles - never did smell him, though. You can always test it out for yourself. Just go out tomorrow morning, ride hard for 12 or 15 miles to be sure, towel off, and ask a friend to smell you at 4pm.
