Any folks in a "hard water" area and a steam iron this is a must have. esp. if you are amazon Prime.
• "No Rush" available so can cost 15p !
"We use this for our iron, even though it has a decalcifier. Why? Even when using decalcifiers on previous irons, I still found that after a while they would expel limescale from the water holes, which would mark clothing.
I find it easier to avoid the limescale problem entirely by using deionised water (which cannot, by definition, produce any limescale)."
