Citric acid is one of the most widespread acids in the plant world. It can be found in almost all fruits, woods, funguses and even in tobacco. Lemon juice is composed of citric acid, between 5% and 7%. It has many uses such as a descaling agent (descaling, removing and dissolving limescale) and making lemonade. It is completely biodegradable too.
Use with caution, reading the label before use is required.
For small and large domestic appliances descaling. Dilute 1 or 2 tablespoons of citric acid in 1L of cold water and use this solution to descale coffee machines and kettles. Rinse with clear water afterwards. You can also use this solution to descale taps, showerheads or pressure reducers. To remove limescale from your washing machine, put 6 to 8 tablespoons of acid in the drum and run on a cycle (90°C).
