Removing scale (or mineral deposits) from a glass kettle is relatively easy and can be done using natural, non-toxic methods. Here’s a step-by-step guide:

1. Vinegar Solution (for Light to Moderate Scale)

Vinegar is a natural acid that breaks down mineral deposits effectively.

What you’ll need:

• White vinegar or citric acid
• Water

Steps:

1. Fill the kettle: Pour a 50:50 mixture of water and white vinegar (or use citric acid) into the kettle, enough to cover the scale buildup.
2. Heat the solution: Boil the mixture in the kettle, allowing it to sit for about 5-10 minutes once it reaches a boil.
3. Let it sit: After boiling, turn off the kettle and let the solution sit for about 30 minutes to an hour (longer for tougher buildup).
4. Scrub gently: Use a soft sponge or cloth to gently scrub away any remaining scale. Be sure to avoid harsh abrasives to prevent scratching the glass.
5. Rinse thoroughly: After cleaning, rinse the kettle several times with water to remove any vinegar or citric acid residue.

2. Lemon Solution (Natural and Fragrant)

Lemon is another great natural remedy due to its acidity.

What you’ll need:

• 1-2 lemons
• Water

Steps:

1. Squeeze the lemon: Cut the lemon(s) in half and squeeze the juice into the kettle, adding the lemon peel if desired for extra cleaning power.
2. Fill with water: Add enough water to cover the scale.
3. Boil: Boil the mixture, then let it sit for 30 minutes to an hour.
4. Scrub and rinse: Scrub gently, then rinse the kettle thoroughly.

3. Baking Soda Paste (for Tough Scale)

Baking soda is a gentle abrasive that can help with tougher buildup.

What you’ll need:

• Baking soda
• Water

Steps:

1. Make a paste: Mix 1-2 tablespoons of baking soda with a small amount of water to create a thick paste.
2. Apply to the scale: Apply the paste directly onto the areas with heavy scale buildup.
3. Scrub gently: Use a non-abrasive cloth or sponge to scrub the area.
4. Rinse thoroughly: After scrubbing, rinse with water to remove the paste.

4. Commercial Descalers

If natural methods aren’t effective, you can use a commercial descaler specifically made for kettles. These products are formulated to dissolve scale buildup quickly. Be sure to follow the manufacturer’s instructions and rinse thoroughly after use.

Tips:

• Regular Maintenance: Regularly clean your kettle to prevent heavy scale buildup, especially if you have hard water.
• Avoid Abrasive Tools: Do not use steel wool or harsh abrasive pads, as they can scratch the glass surface.

With these methods, your glass kettle should stay clean and free of scale.
