Other possibilities not discussed, but discussed previously here on FR:

• Inhalation of Propylene Glycol (PG), based on a 1942 mouse study which showed it was protective against the flu. I understand PG is used to inactivate the flu virus for vaccines. And it has been used as a disinfectant. It's also a large component of vaping products and is used to create stage fog and haunted house fog. Thus relatively safe.
• The Japanese are heating whiskey or other alcohols and inhaling the fumes. The fumes condense in the sinuses and lungs creating a thin layer of alcohol that kills the virus.
• Drink for the cure? The last one raises the question of what effect does raising blood alcohol levels have on the virus? How drunk would you have to get to have a therapeutic effect?

Here’s another provided by FReeper House Atreides:

Heat up glass very hot. Pour very hot water in glass, then pour SAME AMOUNT of liquor e.g. whiskey, etc. into the hot water.

Immediately lean over with towel over head and inhale the alcohol vapors. That kills the virus - supposedly
