My favorite part of this product, by “SmartKlear” [Carbon Smartphone Cleaner], by far: “the same technology used in the NASA space station“. Wow, NASA technology at only $14.95!
“This smartphone cleaner kills bacteria and wipes smudges, streaks, and oily fingerprints right off the screen. SmartKlear uses an invisible carbon substance that repels dirt and oil—the same technology used in the NASA space station”
