Funny thing about the medical field and sanitizing… I had a relative in biochemistry. Their sanitizing regime was very specific. And when asked about hospital sanitizing practices, they could run off a long list of biological hazards common to a hospital setting that not only would not be destroyed by their practices, but were likely to mutate in novel ways.

And yet, other than C.Dif, most people survive visits to the hospital just fine.

So yeah, just the paper towel’s built-in antimicrobial properties are likely enough in most settings where a person would use them… assuming people aren’t using them to pat down a raw chicken and then wipe the counter.
