Limescale buildup results from hard water, where calcium or magnesium is dissolved. When the kettle boils, insoluble calcium carbonate forms from the water which spills into the appliance and remains until the kettle is thoroughly cleaned.
Although there are products specifically designed to remove limescale, many people prefer not to use chemicals when cleaning their homes.
However, according to users on Reddit, you can easily clean limescale using just two natural ingredients.
Posting on a dedicated forum, a user named abir_valg2718 recommended using citric acid and baking soda.
The user said: “Mix [citric acid] with water, do not put a lot, put the minimum and boil.

How to clean the inside of your kettle with citric acid
Boil a kettle half full, then turn it off and unplug it.
Next, add between one and two tablespoons of citric acid.
Leave the critical acid to act for approximately 20 minutes.
Pour out the water and rinse the kettle several times before using it again.
You may need to apply a little elbow grease for more stubborn buildup, but the citric acid should do most of the work.
How to clean rust from kettle parts with baking soda
Baking soda can then be used to clean the rust.
The white powder’s alkaline properties work to break down organic buildup and dirt, while its mineral structure acts as a mild abrasive.
Simply mix water and baking soda into a thick paste, then apply to rust stains.
Let the paste sit for about an hour before stripping the rust.
Then rinse the area and dry thoroughly.
