Citric acid – (C₆H ₈O₇) pH 2 – is a great addition to your list of natural cleaning ingredients as it’s low pH means it is very acidic which means it’s very good for removing things like calcium (limescale), rust, and other minerals. It’s also useful for killing mould and mildew and can be used as a preservative.
Citric Acid is a natural acid compound which is naturally found in many citrus fruits and up until around 1920 citric acid was made from these fruits. However, since then almost 90% of citric acid is now produced by mould-based fermentation (e.g., Penicillium or Aspergillus Niger) of sugars
As soon as you mention the word mould it starts raising alarm bells. However, when producing citric acid commercially the mould is carefully filtered out of the final product, leaving it safe to consume and use around the house.

This is super easy and you will be amazed at the results.
Pour a jug of hot water into the toilet bowl and tip in one to two cups of Citric Acid, sprinkling a lit bit around the bowl as well

When you’re ready just give the toilet bowl a good scrub with a brush and flush.

However, although natural cleaning ingredients are far less toxic and much better to use at home remember that even with natural cleaning ingredients you still need to take care when using them.
There is a slight risk of respiratory symptoms, such as a cough, shortness of breath, and a sore throat, especially in asthmatics, when using citric acid powder. Take precautions to avoid inhalation of the crystals. As it is a mild acid, it can cause eye irritation. Keep away from the eyes. If it comes in contact with eyes, remove any contact lenses and rinse eye(s) with water for several minutes.
