Scale builds up inside any distiller boiling tank, and left alone it slows the unit down and shortens its life. These cleaning crystals are the descaler made for the benchtop water distiller.
They dissolve in the boiling chamber and lift mineral deposits off the stainless steel without scrubbing, which matters in a tank you cannot easily reach into. How often you run a clean depends on how hard your supply water is, and the distiller user manual sets out the method and the dose.
One tub covers a long run of cleaning cycles for a single clinic unit.
