Our citric acid is food-grade and safe to eat, but it is also a highly helpful home product, thanks to its strong acidity, which makes it an excellent cleaning agent. With its strong acidity, it performs an outstanding job of removing quicklime, especially since it is non-toxic to humans; and because it is very water soluble with no odour, it comes off quickly and without streaks! Citric acid is produced naturally in citrus fruits and is frequently used in sweets due to its acidity; unlike sweets, citric acid is highly useful because of its strong acidity quality. Citric acid is ideal for cleaning kettles and other food-handling equipment and supplies because of this.
