If this indeed is the case, anyone with low-temp ovens should immediately be volunteering them up to help sterilize. Hell, I have two of them the Breville countertop convection oven - It'll go as low as 120F steadily, so 158F should be no problem.
Heck, pay the restaurant owners rent to use them — now you’ve solved two problems.
Heck, tell the restaurateurs that when we’re done using their ovens we’ll rip them out and install shiny new ones. Problems that can be solved by throwing money at them are good problems to have right now.
Hospitals have ovens anyway, the ones in their cafeteria kitchens if nothing else. But even if that weren't the case, they could just send somebody to a local store and buy one. They could have it purchased, installed and operational by the end of the day.
But I'd still agree with you.
A residential clothes dryer isn't that much cooler than the temperatures they target in this study. Just use a rack or turn off tumble (if you can).
Employees: N95 masks sir
Customer: can I also order one?
People could do that on their stove with a pot of water and a thermometer.
Source: by far the easiest way to fix crystallized honey is to bake it somewhere in the 120F to 140F range for an hour or two. All the Internet guides saying to use warm water have probably never tried to put a half-full bottle of honey in water, fully submerged to get all the crystals, and without destroying the label. In contrast, all common bottle plastics and labels are just fine in 140F dry air.
And the label is nice if you have lots of varieties of honey :)
Many of them have stackable horizontal racks which may make it possible to 6-12 at a time.
