The Quick Answer
Descale your kettle every 1-3 months depending on water hardness. If you live in a hard water area, monthly descaling is recommended. Soft water areas can stretch to every 3 months.

|---|---|---|
| Kettle | Every 1–3 months | White chalky deposits on the heating element, Flakes floating in your boiled water |
Why Every 1–3 months? (The "Why It Matters")
Limescale buildup makes your kettle work harder, using more energy and taking longer to boil. Those white flakes in your tea aren't just unappetizing—they affect taste and shorten your kettle's lifespan.
Warning Signs You Waited Too Long
If you're noticing any of these signs, it's time to take action immediately:
- White chalky deposits on the heating element
- Flakes floating in your boiled water
- Water takes longer to boil
- Unusual noises during boiling
- Metallic or off taste in hot drinks

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.
