In San Diego maybe... Seriously, I think the alcohol/towell combo is pretty good. I've done it in the past and it works well. Shower before leaving and re-deo upon arrival. Change everything. Don't ride in work clothes or work in ride clothes. And yes I bike to work in full kit.

My situation allows me to bring a weeks worth of food and clothing in on Monday on my muti-geared mule as we've got lockers where I work. I ride a fg the rest of the week w/a seatpost/trunkbag combo. This allows me to bring my soiled clothes home after every workday.
