Soap bits, flakes, tiny specks etc when they land on the floor, stick to the counter, or stick to your pants, can really make a mess.
Anywhooo. I've also noticed that it works without water. This is not a new observation, but just one that I am keenly aware of again in this moment. My office is, ooooh, how to say this, filthy. The bits on the floor have attracted general dirt and become almost sticky little gummy magnets for cat hair, dust bunnies and whatever else is floating around. The bits I have stuck to my pants when I carelessly wipe my hands off, are now stuck to the seat of my office chair. I've got little piles of flecks of all kinds of fuzzy stuff all over.
Whoah. This place needs a deep clean. That's what happens when the sun comes out, even for a few short minutes. You see all the dirt that's accumulated during the last few weeks of dark, stormy, grey days that feel like endless evenings, especially in the basement.
