So there you have it. You are now officially armed with the knowledge to fight the white stuff. You’ve got vinegar, you’ve got citrus, and you’ve got a new favorite word: “squeegee.” Go forth and make your faucets sparkle. Just don’t mix bleach with vinegar. That creates toxic gas. That’s the one time you should not experiment.
Now, go make a coffee. You’ve earned it. And this time, it will taste like victory, not minerals.
