First of all, under no circumstances should you pour boiled water onto the iron. It contains a lot of mineral salts, which settle on the heating elements and clog the holes in the bottom of the device. This may even cause the iron to malfunction.
Water from the cooler is also not the best option. It may contain minerals and impurities that damage the internal components of iron.
Finally, when using distilled water, there is a possibility of encountering corrosion of iron elements.
However, there are some types of water suitable for ironing.
Special water for irons. This is the safest and easiest option. This water can be found in household chemical stores.
demineralized water. For use in ironing, it is better to dilute it 1:1 with normal tap water.
Purified water. It can be used, but only when diluted 1:2 with tap water.
filtered water. This is the most affordable and practical option.
