• To clean with ordinary vinegar: Fill your kettle with half a liter of ordinary
vinegar and wait for one hour. Then, pour away the vinegar and rinse it 2-3
times repeatedly with clean water.
• To clean with citric acid: Once you have boiled half a liter of water, add
25 grams of citric acid and allow it to wait for 15 minutes. Then, empty
the kettle and rinse it 2-3 times repeatedly with clean water. Repeat this
process, if necessary. Always add water when using citric acid, and do not
clean without water.
