How to Maintain and Descale a Kettle

The kettle makes it possible to boil water: the water being more or less calcareous, any kettle ends up scaling up. When scale accumulates in the bottom of your kettle, or on the pouring spout, the filter, the edges… it must be descaled with white vinegar.

This descaling should be carried out regularly: the accumulation of limescale at the bottom of the kettle makes it less efficient and can increase the boiling time of the water. Maintaining your kettle will prevent many breakdowns and extend its life.

A kettle is a staple appliance in many households, used daily to boil water for a variety of needs. Over time, however, limescale can build up inside the kettle due to the minerals present in the water. This buildup can affect the performance of your kettle and the taste of your drinks. Regular maintenance, including descaling, can keep your kettle in optimal working condition. Here’s a comprehensive guide on how to maintain and descale your kettle.

How to Maintain and Descale a Kettle

Part 1: Maintaining Your Kettle

Routine maintenance can prolong the life of your kettle, ensuring it remains reliable and efficient. Here are some steps you can follow:

  1. Regular Cleaning: Always unplug the kettle and let it cool down before cleaning. Wipe the exterior with a damp cloth and mild detergent, then dry thoroughly. Never submerge your electric kettle in water.
  2. Inspect Regularly: Check your kettle’s cord, plug, and body for any signs of damage. If you find any, stop using the kettle and consult a professional.
  3. Empty After Use: To prevent mineral buildup, it’s a good idea to empty your kettle after each use. This practice also avoids unnecessary reheating of water, saving energy.

Part 2: Descaling Your Kettle

Descaling involves removing limescale that accumulates over time from the heating element and interior surfaces of your kettle. Here’s a simple method using household ingredients:

  1. Prepare Your Solution: Fill your kettle halfway with equal parts white vinegar and water. The acid in the vinegar is great for breaking down limescale.
  2. Soak: Let the solution sit in the kettle for 1-2 hours. For heavy limescale buildup, you might need to leave it overnight.
  3. Boil: After soaking, close the lid, plug in the kettle, and let it boil. This will help dislodge any stubborn scale.
  4. Rinse: Discard the vinegar solution, rinse the kettle thoroughly with clean water, then fill it with water and boil again. Discard this water, too. Repeat this step until you no longer smell vinegar.
  5. Clean the Outside: While the kettle is unplugged and cool, wipe the outside with a cloth dampened with the vinegar solution, then with a cloth soaked in clean water, and finally, dry it.

Part 3: Preventive Measures

Taking some preventive measures can help delay limescale buildup:

  1. Use Filtered Water: Filtered water typically has fewer minerals than tap water, reducing limescale.
  2. Regular Descaling: Depending on your water hardness and kettle usage, regular descaling every 1-3 months can keep your kettle in top condition.
  3. Dry After Use: As mentioned earlier, emptying and drying the kettle after each use can prevent limescale and rust.


Proper maintenance and regular descaling are key to extending the lifespan of your kettle, keeping it efficient and improving the taste of your hot beverages. By following the above steps and preventive measures, you can keep your kettle free of limescale and in good working condition for years to come.
