Citric acid is one of the most common acids among plants and is present in almost all fruits, in wood, in mushrooms and even in tobacco. Lemon juice contains 5% to 7%. It plays a central role in the metabolism of all living organisms; the human body produces about 2g per day and breaks it down again. It is also an anti-limestone (it descales, cleans and dissolves limestone) and a formidable antioxidant. Citric acid is completely biodegradable and is one of those basic household products that should be found in every home. Regulatory information: Dangerous – Respect the precautions for use.
