Here’s a trick that feels too simple to work: boil your water. When you bring hard water to a boil, those minerals precipitate out—fancy talk for “they sink to the bottom like a bad idea at a party.” Let the water cool, and you’ll see a white sludge at the bottom. Pour the clean water off the top, and you’ve got softer water for your kettle or pasta pot. It’s like making hard water say “uncle.”
This won’t solve your whole house problem, but it’s perfect for one-off fixes. The next time you’re boiling pasta, just pour off the top layer and watch your sauce come out silky instead of gritty. Your taste buds will thank you, even if your plumbing won’t.
