Why the Water You Use in Your Iron Matters
Using regular tap water may seem harmless, but it contains minerals and impurities that can:
- Cause limescale build-up inside your iron
- Block steam vents
- Stain or damage clothing
- Reduce your iron’s lifespan
That’s why many manufacturers recommend using distilled or deionised water.

Distilled water is purified through boiling and condensation, removing minerals, metals, and organic matter. It’s a top choice for steam irons because it prevents scale and residue buildup.

- 2x5L, 3x5L, and 4x5L multipacks with discount pricing
- 25L bulk containers
