Helps shift limescale in hard water. Hard water contains a whole lot of mineral ions – mostly calcium & magnesium ions. citric acid works by grabbing (chelating) these ions & stopping them forming limescale.
 
Please note that citric acid can become clumpy when exposed to air. It’s fine to use – just break up with a spoon before use.
