Kettle Descaler
100% food grade citric acid
A safe and easy way to descale your kettle
There are many ways to descale a kettle
(Some more successful than others)
The limescale in your kettle is mostly chalk, calcium carbonate (CaCO3), which is a base.
To remove a base you ideally need an acid. Agreed, you could use a stronger base to remove the limescale. Bicarbonate of soda, aka sodium bicarbonate, sodium hydrogen carbonate (NaHCO3) is commonly claimed as being useful for descaling a kettle, but then again you could scrub your garden path with a toothbrush. Its not ideal, its going to take a while - there are more efficient ways.
You could also use a base/acid combination such as baking powder. Baking powder is a usually a mix of sodium bicarbonate (a base) and cream of tartar (tartaric acid). The two when added to water fizz away producing carbon dioxide. When added to limescale the baking powder will fizz away with the limescale as well, but removing the limescale will be a slow old job as its busy doing something else.
So, its best to use an acid, and there are several available.
Hydrochloric acid, this stuff is just dangerous, its not suitable for a domestic enviroment. Avoid!
Phosphoric acid, is a powerful descaler, but its not a nice chemical to work with:
Vinegar, which contains acetic acid. Its safe and is a common item in most kitchens, but vinegar has a few drawbacks:
Lemons, which do actually contain citric acid. They're safe and also another common kitchen item, but lemons also have a few drawbacks:
However, when purified and concentrated Citric Acid has some useful properties.
