If you’ve noticed a white residue or film inside your Alkanatur water pitcher or on your glassware, don’t worry—what you’re seeing is a natural and completely harmless phenomenon called limescale, or calcium scale. It's one of the most frequently asked questions we receive, so let’s break it down clearly and simply.
💧 What Is Limescale?
Limescale is a chalky white deposit made primarily of calcium carbonate, along with smaller amounts of magnesium salts. These minerals naturally occur in water, especially in what's commonly known as "hard water." When water evaporates or is heated, these minerals are left behind on surfaces—like the walls of your pitcher or the inside of your kettle.
⚗️ Why Does It Happen in Alkanatur Pitchers?
Alkanatur filters are specially designed not just to purify water, but to enhance it. Our patented filter adds essential minerals such as calcium, magnesium, and potassium back into the water—minerals that are important for hydration, electrolyte balance, and overall health. This process increases the alkalinity (pH) of your water and boosts its antioxidant power, giving you water that’s both clean and functional.
But here’s the catch: because we're re-mineralizing the water for your benefit, you're more likely to see limescale form over time, especially if the pitcher isn’t cleaned regularly or if the water is left standing for long periods.
🧪 Is It Harmful?
Not at all. Limescale is completely safe and non-toxic. In fact, calcium and magnesium are vital for bone health, nerve function, and muscle contraction. The presence of limescale just shows that your water is mineral-rich—exactly what the Alkanatur system is designed to provide.
That said, we understand it’s not the most attractive look, and if left unchecked, buildup can make your pitcher less efficient over time.
🧼 How Can I Clean It?
Good news: limescale is easy to remove! For light buildup, a simple soak with a mixture of white vinegar and warm water will do the trick. For tougher spots, we recommend using our Resin Remover or Descaling Kit, specially formulated to safely clean your pitcher without affecting the filter or leaving behind any residue.
✅ Tips to Keep Limescale in Check:
- Rinse your pitcher regularly, especially if water has been sitting for more than a day.
- Use filtered water promptly instead of letting it stand for long periods.
- Clean the pitcher with vinegar or our resin remover once every 1–2 weeks.
- Dry thoroughly before refilling to minimize mineral deposits.
In Summary
Limescale in your Alkanatur pitcher is a natural sign of healthy, mineralized water. It may not be pretty, but it’s definitely not harmful. With regular care and the right tools, you can easily keep your pitcher clean and performing at its best—so you can continue to enjoy water that supports your body from the inside out.
