Here is a step-by-step guide on how to clean a tea kettle:
1. Mix water and vinegar in a 1:1 ratio.
2. Pour the mixture into the kettle and let it soak for an hour.
3. Boil the kettle for a few minutes until any limescale separates.
4. Wash the kettle thoroughly with liquid soap and rinse a couple of times.
Alternatively, you can mix baking soda and white vinegar to form a thick paste, apply it to the kettle, let it sit for a few minutes, then scrub the kettle with the solution and wipe it off with a damp cloth. For a deep clean, mix baking soda, lemon juice, and water in the kettle, boil for 30 minutes, then rinse and dry thoroughly. Another method is to combine lemon juice or citric acid with water, bring to a boil, let it sit for 20 minutes, then rinse the kettle thoroughly.
