Now you’ve got a bucket of the most neutral, flavorless, anti-social water on earth. Use it to clean your windows without streaks, or fill a humidifier so you don’t get white dust everywhere. My favorite win: I use DI water for my espresso machine. The mineral buildup stopped, and my coffee tastes like actual coffee instead of rocky grit.

Don’t drink it, though. Seriously, it’s not poisonous, but it will pull minerals from your teeth and leave you feeling dehydrated. It’s like eating celery—you’re just moving water around without getting anything back. Save it for your car battery or your iron. Your body will thank you for sticking with spring water.
The Big Picture
Making DI water is a small, weird rabbit hole that makes you feel like a mad scientist. You take something ordinary (tap water) and turn it into something extraordinary (super boring water). It’s oddly meditative—watching the drip, drip, drip of purified nothingness. And when you’re done, you can proudly say, “I made this. It is the most uninteresting thing I’ve ever produced, and I love it.”
So go ahead, buy a bucket and some resin. Set it up in your garage or laundry room. Accidentally spill a little on the floor and pretend you’re a chemist. The next time someone asks, “How do you make DI water?” you can say, with a straight face, “Easy. Just remove its soul.” They’ll nod, smile, and probably ask you to make a cup of coffee. And you’ll have the perfect water for it.
