So how do you check hardness? Use the shake test. Look for soap scum. Listen to your grumpy pipes. Or just google your local water report. Most towns publish it online. You can find out if your water is “very hard” or “extremely hard.” Yes, those are official scientific categories.
Hard water is weird, funny, and a tiny bit annoying. But now you know its secrets. You can spot a mineral deposit from across the room. You can shame your spotty dishes. And you can always, always blame it for bad hair days.
Go forth. Shake that bottle. Become the hero your plumbing deserves.
