Japanese mobile service provider NTTDoCoMo has installed these special smartphone toilet paper rolls in the bathrooms stalls of Tokyo's Narita Airport. Each wipe has instructions for how to connect to the airport's Wi-Fi, as well as where to go to get other travel information and translation services. They encourage users to use the wipe to clean their smartphone screen to help remove germs. Alternatively, clean your smartphone screen the way I always do: by licking it. I learned that trick from my dog by the way, she cleans everything with licks. Although sometimes she gnaws a little if she has a dingleberry, which she did this morning after our walk. "TMI." Caring means sharing.
Keep going for one more shot.
Thanks to rahul, who agrees the best way to clean a smartphone is in a dishwasher on the pots & pans cycle.
