The standard advice to wash hands frequently is worthwhile but leaves many gaps.  Suppose the restroom door swings inward, as it does in several markets I visit.  However well I wash while in the restroom, I can’t leave it w/o grabbing a handle whose last grabber may not have washed enough (if at all) to get the virus off his hands.  And so on.

When I must go shopping, I now carry a small flask of isopropyl alcohol (the active ingredient in hand sanitizers) and an absorbent rag or washcloth.  I can wipe my hands just before and/or after touching anything that might carry the virus.  I don’t need to sprint to a wipe dispenser and then toss a used wipe onto the pile that is already overflowing a wastebasket (if there even is a wastebasket there).

The flask and damp rag fit nicely in a pocket of my photographer-style vest.  Don’t have or want such a vest?  Appropriate outer pockets are on many gadget bags, gym bags, purses, and so on.  Buying one may be easier than buying toilet paper.
