Limescale

[racket]

Hi,

I wonder can anybody help, I am having a problem with limescale forming on the heater elements in an industrial humidifier (basically it's just a big Kettle) Is there any product I can use that I can dilute and leave to soak on these elements that will get rid of the limescale, I'm not too keen on acid as we will have to go down the line of disposing off it in the correct manor, the scale is some 3mm thick in places.

Cheers

What are these thingies that are advertised to stop limescale? they have a coil of wire around the rising main pipe. Do they work?
