How to clean the scale in the electric kettle

The scale in electric kettles is mainly formed by the deposition of minerals in water (such as calcium, magnesium, etc.). Scale not only affects the heating efficiency of the electric kettle but also may affect the taste and health of drinking water. The following are some effective methods to remove scale from electric kettles:

1. White vinegar method:
   Fill the kettle with water and add white vinegar at a ratio of approximately 1:1.
   Turn on the electric kettle to heat until it boils, then turn off the power and let it soak for about 1 hour.
   After soaking, use a sponge or soft cloth to wipe the inner wall of the kettle, and the scale will gradually fall off.
   Finally, rinse thoroughly.
2. Citric acid method:
   If there is citric acid powder or tablets, add an appropriate amount of citric acid to the electric kettle according to the product instructions.
   Add water, heat until it boils, then turn off the power and let it soak for a period of time.
   After soaking, use a sponge or soft cloth to wipe the inner wall of the kettle, and the scale will gradually fall off.
   Rinse clean.
3. Carbonated beverage method:
   Pour carbonated beverages (such as cola) into the electric kettle and let it soak for a period of time.
   After soaking, use a sponge or soft cloth to wipe the inner wall of the kettle, and the scale will gradually fall off.
   Rinse clean.
4. Hot water soaking method:
   Fill the electric kettle with water and add an appropriate amount of edible alkali (such as baking soda).
   Heat until it boils, then turn off the power and let it soak for a period of time.
   After soaking, use a sponge or soft cloth to wipe the inner wall of the kettle, and the scale will gradually fall off.
   Rinse clean.
5. Toothpaste method:
   Use ordinary toothpaste and apply it on a soft cloth or sponge.
   Wipe the inner wall of the kettle with toothpaste, especially where the scale is thick.
   After wiping, rinse with clean water.
   When cleaning the electric kettle, make sure there is no residual detergent in the kettle to avoid affecting the hygiene of drinking water. In addition, regular cleaning of the electric kettle can effectively reduce the formation of scale. If the scale problem is serious, more frequent cleaning may be required.
