I don't lick my phones, so I don't worry about sanitizing them. usually a microfiber cloth or my t-shirt does the job. If it gets really dirty I'll run one of those computer monitor anti-static wipes over it and follow up with the microfiber cloth. That said, as much as I don't like the look of all the smudges, most of the time I just leave it be because the pizza grease and stuff makes it a lot easier to slide my fingers around on the screen.
I am an optician so I work with glasses and cleaning them and what not. We use a mixture of 60% denatured alcohol and 40% water it works great, no streaks, no grime everything is well on my storm and the doctor that works with us as well!
