Pure Steam

How does hard water damage clothes and irons?

   Choosing the right water is one of the simplest ways to extend the lifespan of your iron or garment steamer. Water quality has a direct impact on how household appliances function: hard water causes scale buildup, leaves white marks on clothing, and makes the device heat up more slowly. Understanding the differences between water types helps ensure effective, safe, and long-lasting operation.

Types of water and how they affect your appliance

1. Tap water

In many regions tap water is hard and contains high levels of calcium and magnesium. As a result:

  • scale builds up inside the iron,
  • the device heats more slowly,
  • steam becomes uneven,
  • white or dirty spots may appear on clothes,
  • the iron may fail prematurely.

2. Filtered water

The safest and most suitable water for irons and steamers is filtered water. Filtration removes:

  • hardness salts (Ca, Mg),
  • mechanical impurities,
  • chlorine
  • and other contaminants.

Filtered water:

  • prevents scale,
  • protects clothing from stains,
  • improves steam efficiency,
  • significantly extends the appliance's lifespan.

It can be produced with pitcher filters or reverse osmosis systems.

3. Distilled water

Although it may seem ideal, distilled water is not always recommended:

  • lack of minerals makes heating slower,
  • steam forms poorly,
  • water spots may remain on clothes,
  • corrosion develops faster inside the device.

It is safer to mix distilled water with tap water.

What water should never be used?

  1. Boiled water – impurities remain.
  2. Well or spring water – mineral content is too high.
  3. Mineral bottled water – guaranteed scale.
  4. Water with essential oils or fragrances – oils stain fabric and damage the device.

Can you use an iron without water?

   Yes, you can. But steaming removes wrinkles more effectively and is gentler on delicate fabrics.
