I don't know what I do to them - I've tried upper price range, and now I go with cheap (in an almost disposable/landfill-unfriendly way), and have yet to come across an iron that makes me think I've hit the iron Holy Grail.
I live in a very very hard water area which I suspect is the root of the problem, and haven't had great success with limescale removers - eventually they clog up completely and become steam-free.
How long is the average iron meant to last for anyway?
Any recommendations gratefully received.
