Hydrogen peroxide is basically water with an extra oxygen atom, like a water molecule that drank too much coffee. That extra oxygen is super reactive, meaning it’s eager to bump into things and cause chaos.
When it meets a virus, it unleashes free radicals—think tiny, angry Pac-Men—that tear apart the virus’s outer shell and genetic material. Poof! Virus becomes a sad, broken little blob. It’s like hitting “delete” on a file.
But here’s the catch: it only works if the peroxide stays wet long enough. If it dries up, the party’s over. So don’t expect a quick spritz to be your viral bodyguard.
