Frequently Asked Questions

Is limescale in my kettle harmful?

Limescale itself isn't harmful to health—it's just calcium carbonate. However, it affects taste and kettle efficiency.

Can I use lemon juice instead of vinegar?

Yes! Lemon juice contains citric acid and works well. Use the juice of 2-3 lemons mixed with water.
