Here’s a trick: fill an ice cube tray with tap water, freeze it, then let the cubes melt in a clean bowl. Why? Freezing concentrates impurities in the liquid center, so the first ice to melt is slightly purer. It’s not perfect, but for a last-minute CPAP machine fill or a quick iron refill? It’s a hilarious, low-rent hack.
What Can You Substitute For Distilled Water at Christian Brown blog
Just don’t tell your granola friends you’re using “ice water” for your algae farm. They’ll think you’ve gone rogue.
The Ultimate Lazy Move: Buying It
Look, sometimes the best substitute for distilled water is… distilled water. A gallon costs about $1.50 at the grocery store. That’s less than a fancy coffee. If you need it for a medical device, a high-end espresso machine, or a sourdough starter that’s been in your family since 1842, just buy it. Your sanity is worth more than a DIY disaster.
But for everything else? Tap water with a pinch of salt (kidding—please don’t). Honestly, most recipes that call for distilled water are just being extra. Like that friend who only drinks from a specific brand of bottle. You can roll your eyes and still use filtered water.
