It is called Lysol if your cheap. That said, I looked at it as a way to keep my immune system primed. Never got sick from mask reuse, but did get bad bronchitis for a week or so because I didn't wear a mask once during a public outing after the ban was lifted.

Lesson learned. Eitherway, due to my genetics, if I got Covid, I would probably not even know or barely feel it, so contingency planning is still in effect to heal the damage Covid does to the body once things ease up a bit.
