In order to ensure that your sterilizer and bottle/ food warmer is working with 100% efficiency, you need to remove the limescale every 4 weeks and even more frequently for regions where the water is hard.
How to use:
Pour 10 gr (a dessert spoon of) descaling powder into the unit filled with 200 ml of water.
Run your sterilizer for a minute or two while its lid is closed.
Bottle/ Food Warmer:
Run your warmer for 10 minutes at highest temperature possible.
Then turn off and wait for 30 minutes.
Clean the inside of your product and activate it again at normal mode for few times and empty the water inside.
