Here's why:
* Limescale is formed from calcium and magnesium salts. These salts are dissolved in hard water.
* Deionised water has had its ions (including calcium and magnesium) removed. This makes it very pure and free of minerals that cause limescale.
So, while boiling deionised water won't cause limescale, it's important to remember:
* Deionised water is not ideal for drinking. It can taste flat and lacks essential minerals.
* Deionised water can be corrosive to some metals.
If you're concerned about limescale, consider using a water softener or filtering your water.
