There is really interesting research being done by Outbreaker Solutions in Canada, where researchers are looking into making door handles and other fixtures from impacted salt, because it has been found that viruses survive for a shorter time on salt than on many other surfaces.

Here’s a guide to how long coronaviruses — the family of viruses that includes the one that causes COVID-19 — can live on some of the surfaces you probably touch every day.
Different Kinds of Surfaces
Examples: doorknobs, jewelry, silverware
Examples: furniture, decking
Examples: milk containers and detergent bottles, subway and bus seats, backpacks, elevator buttons
2 to 3 days
Examples: refrigerators, pots and pans, sinks, some water bottles
2 to 3 days
Examples: shipping boxes
Examples: pennies, teakettles, cookware
Examples: soda cans, tinfoil, water bottles
2 to 8 hours
Examples: drinking glasses, measuring cups, mirrors, windows
Up to 5 days
Examples: dishes, pottery, mugs
Examples: mail, newspaper
The length of time varies. Some strains of coronavirus live for only a few minutes on paper, while others live for up to 5 days.
