now hold on hold on, i got you buddy. if you're worried about contaminating the hand sanitizer when you have dirty hands, then you wouldn't be employing the no cross-contamination-tactic.
you would only dirty your left hand by touching things in the world, and your right hand would be the one with the hand sanitizer and your phone, so your right hand would never get dirty. make sense?
although this is kind of ridiculous LOL
it might work enough to be worth it for you.
