How does soap kill COVID-19?

Ok so we've known for awhile how soap works in a general use sense, like how it cleans dishes (see episode 1). But these weird times call for a deeper look at soap. How can it kill a virus? Or more importantly, how can it kill a little, wretched, mischievous virus like COVID-19? Like really, how? How is it that we can use soap to both get spaghetti sauce off a plate, and kill a dangerous virus? We're always told to wash our hands well, and that it's important, but if you think about it for a second, it's crazy that we put something on our hands, and rub them together under water, and then we're good to go. Right? Let's get into it.
