How to Descale a Kettle and Keep It Scale Free

Updated on March 9, 2015

How And Why Does Limescale Form Inside A Kettle?

You are probably familiar with your kettle furring-up with limescale deposits because you live in a hard water area. And with over 60% of the population in the UK living in a hard water area or where ever you live in the world with similar conditions, limescale deposits inside a kettle is a common problem.

Limescale is largely made up calcium and magnesium ions dissolved in the water and when the water is heated, these calcium and magnesium ions are separated from the water molecules, which are then attracted to the sides of the kettle or heating element, forming the crusty white deposits we know as limescale.

Lets face it, there is nothing worse than pouring bits of limescale into your cup of tea or coffee, not to mention the amount of extra electricity that has to be used to heat the same amount of water compared to a limescale free kettle.

Traditional Kettle Descalers

There are several different types of chemical descaler available to get rid of the limescale or scale inside a kettle. Chemical descaler react with the calcium and magnesium ions, dissolving them into solution. It is only a short term solution, because as soon as water is boiled, the calcium and magnesium ions will continue to form scale on the inside of the kettle once again.

Another popular solution is to put a piece of stainless steel wire mesh inside the kettle and this is supposed to attract the calcium and magnesium ions. This works for a while, but again is not a good long term solution as it has to be replaced after a period of time.

EM Kagen Kettle Descaler

Now there is a new type of kettle descaler on the market that provides a long term solution to removing scale from existing kettles and preventing further limescale from forming. Originally developed by Dr Teruo Higa from Japan, Kagen EM™ Ceramic is not a descaler in the traditional sense, but provides continuous protection against the buildup of limescale inside kettles or even coffee machines.

When left in the water of a water filter jug for at least 30 mins, the specially prepared piece of ceramic and its amazing properties are able to stop the calcium and magnesium ions from clustering, keeping them in suspension, thus preventing limescale from forming; even if your kettle has limescale in it, it will gradually dissolve this away too.

The Kagen EM™ Ceramic Kettle Descaler can be put directly in to a kettle and within a couple of hours the limescale will soften, which can then be scraped or brushed out. When left in a kettle, some limescale may continue to form on the kettle sides, but this will always remains soft and never amounts to much, thus making it easy to clean with a brush. Watch the Youtube clip to see the results.

EM™ Kagen Ceramic is chemical free and is 100% natural, therefore, it is good for the environment, and also eliminates the risk of someone accidentally drinking any chemical descaler.

Because we live in a hard water area, I have used it in my own kettle at home for over a year and it has proven to be very effective at preventing scale from forming; I have also had many favourable comments from friends who have used it too.

Well recommended!!!

      Ok so now you are consuming the limescale instead of it being kept in the kettle, is that a good idea? Are there any long term implications of that?
