Citric acid is one of the most common plant acids. Osmose's Non-Toxic Citric Acid Powder has a place of choice in every home for cleaning and descaling. It is mainly used for descaling household appliances and removing limescale from bathrooms and washrooms.
For taps, showerheads and water reducers: Mix 2 to 5 tablespoons of citric acid with water. Scrub the limescale-affected areas with this solution and leave to act before rinsing. For smaller objects, you can leave them to soak in this solution for half a day, then rinse.
