One important note that people tend to overlook-- make sure your OWN hands are clean. When you've been traveling and touching a lot of things, break out the Purell and clean your fingers well. You have no idea what's hiding there. Good thing is that in Mexico, most places, even the most unlikely ones (except for food stands) have sinks with soap.

Surely you jest. I encourage you to visit Mexico, and see first-hand.

I can find a sink with soap even in the Mercado de Antojitos in Pátzcuaro. The water is cold and there are no towels, but it works.
