How to Know If Your Water Is Hard

How to Know If Your Water Is Hardの効果的な手順を詳しくまとめたします。初心者から上級者まで必見の内容です。

Pull out a glass from your dishwasher. Does it have those cloudy spots or a gritty white film? That’s hard water etching the glass. Those spots aren’t dirt—they’re mineral deposits baked on by the heat.

If your plates feel slimy even after a wash, or you see rainbow streaks on your silverware, it’s the water doing its thing. You can rinse them ten times, and it won’t change a thing. Frustrating, right?

The Squeaky Clean Myth

Here’s the irony: hard water makes your dishes and skin feel “squeaky.” But that squeaky feeling is actually soap scum sticking to you. Real soft water leaves a silky, smooth feel—not that psychological “I’m so clean” squeak your brain craves.

So if your skin feels tight and dry after a shower, or your hair feels straw-like, don’t blame your products. Blame the water messing with your pH balance.
