Cleaning your nozzle

[PobodY]

As a suggestion, why not use something like citric acid? - When I was fixing my espresso machine the forum gurus told me to use citric rather than acetic acid (vinegar); there's not the issue with the smell nor residual taste... obviously the taste of acid isn't an issue when cleaning a nozzle. :roll:

In all honesty though, I found hydrochloric acid to be the best for removing limescale. - I'm not sure if that would damage a nozzle though.
