The best solution is really to buy a kettle with a concealed element -
these don't seem to scale up as fast and they're easier to clean.
That was not true in my case.
I had to descale my concealed element jug kettle every 3 months or so.
Then it started leaking though the water level guage tubes, so I threw
it away.
I am now using my 30-year-old Russell Hobbs; somehow, the limescale
flakes off rather than building up.
