What it's good for
Gets into the gaps
Presses into vents, seams and keyboard keys that a cloth just pushes dirt further into.
Fold for a fresh face
Kneading it over buries the dirt and brings clean gel back to the surface.
Knows when it's finished
It goes soft and discolored as it loads up with dirt. That's the signal to throw it out, not to wash it.
