Can Citric Acid Be Used for Cleaning?

Citric acid sounds intimidating, but you’re probably more familiar with it than you think. Chemically speaking, citric acid is an organic compound with the formula C6H8O7. 

But what is citric acid in practical terms, and can it be used for cleaning? Let’s find out!

 

What Is Citric Acid?

Citric acid is an organic compound that commonly occurs in citrus-based fruits like lemons and limes.

It is a popular cleaner because it can remove harmful bacteria, it can eliminate mildew, and can be used as a general disinfectant around the home. 

In addition to this, citric acid is very good at removing limescale that is caused by hard water.

So, where does citric acid come from?

There are two main ways to get citric acid:

  1. Naturally – The first way you can get citric acid is to source it naturally. This kind of citric acid typically comes from fruits like lemons and limes, and is harmless to humans, unless they’re eaten in vast quantities. 
  2. Artificially – The second way you can get citric acid is by manufacturing it. This is how a huge amount of citric acid is created around the world! Manufactured citric acid is created through a fermentation process, and this process involves the mould aspergillus niger metabolising a product like glucose. The end result of this entire process is a by-product known as citric acid. 

Of course, it’s worth pointing out that while citric acid is safe, you should avoid digesting too much of the natural product, because it may make you sick. 

And you should really avoid eating the manufactured version, just in case you get side effects. 

 

Can You Use Citric Acid When Cleaning?

Yes, you can use citric acid when cleaning your home. 

It’s a non-toxic item that can remove some of the toughest dirt in your house, and it’s not too expensive to get hold of citric acid either! It’s an all-round great product. 

Manufactured citric acid is also an ingredient in several well-known cleaning items. For example, you can sometimes come across this citric acid in dishwasher cleaners and multipurpose bathroom cleaners. 

So, you might’ve been using it around your house without knowing anyway.

Both citric acid and vinegar are natural and safe cleaners, and they are both good at cleaning items around the home. However, they both have their drawbacks. 

Some people prefer to work with citric acid because it’s more convenient to locate a lemon in a shop, and it smells better.
