what water should you use for ironing?

If you’re just a regular person who has simply stumbled on this page because you’re looking for a new iron to buy, you may find it peculiar that someone may ask the question of what water you should use in your iron. Water is water, right? Not necessarily…

In the past, you may have just used tap water in your steam iron or your steam generator iron, that is what most people do. The problem is that tap water can vary depending on what area of the country you live in. You might have heard of “hard water” and “soft water” but may not necessarily understand what these terms mean and how they can affect your ironing. Firstly, I’d like to show you the below image, which is a map of the UK, showing water hardness in the uk:

Enough with the boring science, basically hard water is safe to drink and bathe in etc., but due to the higher than soft water (but still very low) levels of minerals which is contained within the water, this can cause things like limescale etc. to build up at a rapid rate inside your iron and lead to faster damage and a shorter lifespan.

So you may ask what sort of water you should use if not hard water. Most manufacturers demineralised water as an option which is less corrosive to the inside of your iron, however the problem with demineralised water is it can cause the water in your iron to “spit” more. You can buy this sort of water from any good retailer.

The general consensus seems to be that if you are conscious of making your iron last as long as possible (this may be very important to you if you’re spending a lot of money on an iron), a 50/50 mix of tap water and demineralised water may be your best option. Ultimately though, these days many irons have special filters and anti-calc cartridges which prolong the lifespan of your iron. It is worth checking out the features of your iron to see if there is anything in place to prevent damage to your iron from hard water and then make a decision from there.
