A viral TikTok hack using citric acid removes limescale from kettles in seconds, according to a user who tested the method. The hack requires only citric acid, a common kitchen staple, and water.
How the Citric Acid Hack Works
The user, a working mum, filled her kettle halfway with water, added two teaspoons of citric acid, and boiled it. After letting it sit for 15-20 minutes, she poured out the water to find the kettle completely free of limescale. She then rinsed thoroughly and boiled plain water to remove any residue.
Why Citric Acid is Effective
Citric acid is a natural, non-toxic, food-grade acid that reacts with limescale (calcium carbonate) to dissolve it. Unlike vinegar, it is odourless. The hack is safe and ideal for regular descaling.
Step-by-Step Guide
- Fill the kettle halfway with water and bring to a boil.
- Add 1-2 teaspoons of citric acid; it will fizz immediately.
- Let the mixture soak for 15-20 minutes. For heavy scale, reboil briefly and soak longer.
- Pour out the solution, rinse the kettle thoroughly with fresh water, then boil a full kettle of plain water to discard any residue.
According to the user, the hack saved time and effort, making the kettle look brand new. She recommends not leaving the citric acid solution for too long to avoid forgetting it before making tea.
