How to Descale a Krups Electric Kettle

Tea lovers may choose a Krups electric kettle for heating and keeping their water piping hot. You must descale the Krups electric kettle regularly to prevent a buildup of scale deposits from hard water. Depending upon how hard your water is, this may be as often as once per month.

Step 1

Pour 2 ¼ cups of white vinegar into a measuring cup. The white vinegar must be 46 degrees F, so chill in the refrigerator until it is this temperature. Use the instant-read thermometer to measure the temperature of the white vinegar.

Step 2

Pour the white vinegar into the Krups electric kettle. Allow the vinegar to sit in the electric kettle for one hour without heating the kettle.

Step 3

Pour out the vinegar after one hour. Rinse the inside of the electric kettle six times with cool water.

Step 4

Fill the kettle with water to the maximum fill level and boil the water. Discard the water. Fill the kettle to the maximum fill level again and boil the water again. Discard the water without using it, then use your Krups kettle as usual.

Step 5

Citric acid is also an effective descaler. Place 2 ¼ cups of water in the kettle and boil the water. Turn the kettle off and add 1 1/2 tbsp. of citric acid to the hot water and allow it to sit in the kettle for 15 minutes. Follow Steps 3 and 4 to rinse the electric kettle.
