Hard water spots are actually fascinating. They are the physical proof that water is not just “wet.” Water is a solvent. It grabs tiny bits of rock from the earth and carries them to your showerhead.
You are, in a way, cleaning up the planet’s crust. That’s deep. Or shallow. Either way, it’s a thing.
So go forth. Grab your vinegar. Squeegee your life. And remember: every spot you remove is a tiny victory over geology. You rock. (Pun absolutely intended.)
