Citric acid is a powerful, non toxic cleaning and preserving agent that is found naturally in lemon juice. Although in its anhydrous or granulated form, it is much more potent. It has loads of great applications for household cleaning, here are just a few.
We’ve all been there; take the last mouthful of your cup of tea and it’s full of crunchy pieces of limescale. Time to descale the kettle!
You can easily and quickly clean your kettle using citric acid. Simply add half a tablespoon of citric acid to a kettle full of water, boil, then rinse. If the limescale is especially bad, use a whole tablespoon of citric acid, or boil the kettle twice.
Once you're done cleaning the kettle, don’t throw away the mixture! Transfer to a heatproof bowl or tub big enough to house your shower head and allow it to soak in the solution for 10-15 minutes to remove any limescale buildup before rinsing off.
You can also make a really effective bathroom limescale spray by diluting 100g of citric acid into half a litre of boiling water. To this mixture you can also add 30ml of castille soap for scent and extra cleaning power. Allow to cool and transfer to a reusable spray bottle. Spray the solution onto taps, shower screens and plugholes; anywhere there is a build up of limescale. Let it sit for a few minutes and clean off. Depending on the stubbornness of your limescale, you may need to apply a couple of times.
You can also use citric acid to make a fizzing toilet cleaner, as outlined in this post.
Although it is non-toxic, citric acid is still a corrosive agent and can harm surfaces such as marble, limestone, copper and brass.
