We have shocking hard water here and limescale is taking over appliances, killing kettles and drinking gallons of vinegar, viakal and washing machine tonic.
I've seen devices for sale in Wilkinsons/local hardware stores which clip onto a water pipe and claim to resolve the issue. There is usually a television (JML-style) with a chap claiming extraordinary benefits. Has anyone used such a device? Did it work? Or is there a simple solution I don't know about?
