    Citric acid as a household remedy

    Versatile and powerful against limescale

    Acids are the business when it comes to descaling. With their ability to dissolve lime, they’re just what you need to remove unsightly limescale deposits, water stains, and stubborn scaling.

    Citric acid: naturally powerful

    Using citric acid is a powerful, yet natural, way to tackle limescale. It is so called because it was first isolated from lemons, a citrus fruit, by chemist Carl Wilhelm Scheele in 1784. However, it is also found in many other fruits and even in living organisms. Why? Because citric acid is naturally produced during metabolism, including by humans.

    From sustainable raw materials

    It takes immense effort to obtain large quantities of pure citric acid from real lemons. That is why demand for citric acid among food and detergent manufacturers is met by fermenting molasses, a by-product of sugar production, or starch, for example. Therefore, citric acid is obtained from sustainable raw materials and is itself fully biodegradable.

    Fragrant—because there’s no smell

    Vinegar is another familiar household remedy used on limescale. It has a similar effect to citric acid and removes limescale through its acidity. However, vinegar has two significant drawbacks: its strong smell and its vinegary taste. Citric acid is odourless. It does have a sour taste, but this does not linger in appliances after rinsing. This makes citric acid an excellent choice when descaling and cleaning electrical devices, fittings, and surfaces.

    Food-safe descaling

    Citric acid is a small but important element of many foods. Juices, lemonades, and sweets contain citric acid, as do jelly and ready meals. Citric acid enhances the taste, inhibits microbial decay, and has an antioxidant effect.
    Citric acid is therefore suitable, in principle, for use in food. This also makes it an attractive limescale remover, especially for descaling household appliances that come into contact with food.

    HEITMANN Pure Citric Acid should not be used for food. Although it is pure citric acid, the fact that it is sold as a cleaning agent means that the filling process does not meet the guidelines for food production.

    Banish limescale: how to use HEITMANN Pure Citric Acid

    HEITMANN Pure Citric Acid comes in three different forms: a concentrated powder, predissolved in a bottle, and in a practical spray bottle (on sale from March 2020). The powerful and environmentally friendly formula in all three dissolves limescale throughout your home. We’ve compiled information here on how this works.
