No. Distilled water does not have chlorine. At least, not in any meaningful amount that would matter to you, your fish, or your precious espresso machine. The distillation process is basically a high-tech kidnapping of water molecules.
Here’s how it works: you boil the water until it turns into steam, then you catch that steam and let it cool back into liquid. The chlorine—along with minerals, bacteria, and pretty much everything else—gets left behind in the boiling chamber. It’s like throwing a party for water and telling all the unwanted guests (chlorine included) to stay in the kitchen.
So if you’re worried about chlorine ruining your plants or making your tea taste like a swimming pool, distilled is your best friend. But hold your horses—there’s a twist.
But wait, doesn’t tap water have chlorine?
Oh, absolutely. Municipal tap water is basically a chlorinated soup. That’s on purpose—it kills nasty microbes so you don’t get a surprise case of dysentery from your morning glass. Chlorine is a hero, really. Just not a tasty one.
Distillation removes that chlorine like a bouncer ejecting a loud drunk from a bar. The steam rises, the chlorine stays behind (or gets vented off, depending on the setup). So if you’re buying a jug of distilled water from the store, you can bet your bottom dollar it’s chlorine-free. Mostly.
