There's a go-kart track near me... and they have someone who goes around after each session and sprays some kind of fog on the karts. I presume it's a "sanitizer" but if you look how sanitizers work, they still take time to act and it takes a decent quantity of it to work. Meanwhile the steering wheels are covered in pourous foam / plastic / rubber, which is soaking up everybody's sweat, germs and bacteria... and some how this fog, which is safe for the person spraying it to stand in, sanitizes the entire kart in under a few seconds and leaves behind no residue...
