Electric kettles are a common household appliance, providing hot water in a matter of minutes. However, over time, the inside of the kettle can become coated with stubborn white mineral deposits that are difficult to remove.
This buildup is primarily caused by the presence of minerals such as calcium and magnesium in the water. When the water is boiled, these minerals precipitate and adhere to the walls and base of the kettle, forming a hard, white crust. This is especially prevalent in areas with “hard” water, where the problem can be more rapid and severe.

Strong Chemicals Can Be Harmful
Many people attempt to remove these deposits using various cleaning agents, from dish soap to strong chemicals, but to no avail. In fact, the use of harsh chemicals can damage the non-stick coating or even pose health risks.
White Vinegar – The Secret to a Spotless Kettle
There is a simple, inexpensive, safe, and effective solution: white vinegar. This common household product can quickly dissolve even the most stubborn mineral buildup.
Instructions:
- Pour approximately 300ml of white vinegar into the electric kettle.
- Add about 300ml of clean water.
- Plug in the kettle and bring the mixture to a boil as usual.
- Once the water has boiled, unplug the kettle and allow the solution to sit for 15-20 minutes to ensure it penetrates the mineral deposits.
- Discard the vinegar-water mixture and rinse the kettle with clean water. Repeat this process 1-2 times to ensure a thorough clean, and your kettle will be sparkling like new!
Citric Acid from Fresh Lemons Also Does the Trick
If you don’t have white vinegar on hand, fresh lemon is a suitable alternative. Cut a few thin slices of lemon and place them in the kettle with a moderate amount of water. Bring it to a boil and allow it to cool, just as you would with the vinegar. The natural citric acid in lemons effectively breaks down mineral buildup.

Baking Soda – A Safe and Gentle Cleaner
Baking soda is another excellent and gentle option. Simply dilute some baking soda and use it to soak and lightly scrub the kettle, achieving impressive results without any risk of damage.
Tips to Prevent Mineral Buildup
To minimize mineral buildup, it’s recommended to clean your kettle regularly, at least once or twice a month. Additionally, avoid leaving water sitting in the kettle for extended periods. After use, rinse and dry the inside of the kettle thoroughly.
By following these simple tips, you can maintain a spotless and long-lasting electric kettle, ensuring that the water you boil is always safe for consumption.
