If you’ve noticed white chalky build-up, slower boiling, strange tastes, or weaker coffee, your appliances are likely suffering from limescale. Descaling your electric kettle and coffee maker regularly keeps them efficient, hygienic, and long-lasting.

 

Why Descaling Matters

Limescale forms when hard water minerals (mainly calcium and magnesium) build up inside heating elements.

Problems caused by limescale:

• Slower boiling time

• Higher electricity usage

• Altered taste in drinks

• Reduced appliance lifespan

• Potential clogging in coffee machines

Most homes should descale every 1-3 months, depending on water hardness.

 

How to Descale an Electric Kettle

What You’ll Need:

• White vinegar or lemon juice

• Water

• Soft sponge or cloth

Method 1: Vinegar Method (Most Effective)

1. Fill the kettle halfway with equal parts water and white vinegar.

2. Boil the solution.

3. Turn off and let it sit for 20-30 minutes.

4. Pour out the mixture.

5. Rinse thoroughly 2-3 times.

6. Boil clean water once and discard to remove any lingering taste.

Method 2: Lemon Method (Natural Alternative)

1. Fill the kettle with water.

2. Add juice from one lemon (or 2 tablespoons lemon juice).

3. Boil and let sit for 20 minutes.

4. Rinse thoroughly.

💡 Tip: For heavy build-up, repeat the process.

How to Descale a Coffee Maker

What You’ll Need:

⚠️ Never mix vinegar with bleach or other cleaners.

How Often Should You Descale?

• Hard water areas: Every month

If your appliance has a descaling indicator light, don’t ignore it!
