Or is it just a placebo? Anyone know?

Well, our old washing machine has lasted 12 years and doesn't have much sign of build up of scale on the element. But out kettle furs up quite quickly.

So, I think it is tosh, IMHO of course.

Use Citric Acid to get rid of build up. (From the local chemist)

USe it on a boil wash

Calgon is more a preventative measure

Been advised by a washing machine rapair man just to use 50ml of vinegar on a 90 deg C wash (and to put fabric conditioner in like you'd do normally......as it'll stop it smelling after) as it does the same thing at a fraction of the cost. I do this once every few months and it does come up like a new pin!
