You ever hear of that thought question “Does soap get dirty”?

if the sock did get clean, then the stuff making the sock dirty… went somewhere. I submit that not only did your sock not get clean, it made the other clothes not clean, too.

Nn…ooo???

if your hands were covered in mud and you dried the mud, would your hands be clean or covered in dried mud?

No

It’ll make it warm and dirty.

The dryer doesn’t clean clothes, so that would be just putting a dirty sock in with your clean wet clothes.
