Does Coca Cola really remove rust?

Coca Cola is a sugary fizzy drink that many people blame for contributing towards the world obesity epidemic.

This video shows how Coke can be used to remove rust:

What’s in cola that makes it remove rust?

pH is an indicator of how acidic or alkaline a substance is.

Pure water has a neutral ph level of 7.

If a substance has a ph of less than 7 then it is acidic, if it is greater than 7 then it is alkaline.

ph Level of Coca Cola

Coca Cola has a pH level of 2.8.

The ph level of Coca Cola is 2.8 according to This means that it is acidic.

Coke is so acidic that it can dissolve a nail in four days, and it is slightly more acidic than vinegar.

That could be why the manufacturer adds such a lot of sugar (or artificial sweetener in the case of Diet Coke) to make it palatable.

Is Coke safe to drink?

Carbonated drinks are known to irritate the stomach, so any fizzy drink isn’t great for our health.

Coke contains approximately ten teaspoons of sugar, this causes a leap in insulin levels within the body.

It is also high in caffeine, which can lead to an increase in blood pressure.

The phosphoric acid in Coke binds to calcium, magnesium, and zinc in the gastrointestinal tract.

This could prevent minerals from food being absorbed effectively by the body, and may be eliminated through urination.

Coke also contains E211 (Sodium Benzoate), which is an anti-fungal, and anti-bacterial agent.

According to research from Sheffield University sodium benzoate may have a “deactivating effect” on DNA.

More research needs to be done to fully understand the long term effects of drinking high sugar acidic beverages.

Possible dangers of drinking Coca Cola regularly:

  • Leeching of calcium from bones
  • Acid reflux
  • Damage to the stomach lining from the acid

How Coke effects the acid/alkaline balance in the human body

Over-acidity can weaken every one of the systems in the body.

Some health experts claim that all disease stems from having too much acid in the body.

You can test the PH level of your own body using pH test strips.

A healthy pH range is between 6.5 and 7.5 all day.

If your pH level is below 6.5 then you may want to reduce the amount of acids you are consuming in your diet.

This could include reducing the amount of acid beverages, such as Coke, and acids on your food such as vinegar.

People who have too much acid for too long may develop acidosis, a condition where the body is attempting to neutralise the acid by leeching out calcium, sodium, potassium, and magnesium from vital organs and bones.

Acidosis is linked to obesity, bladder and kidney conditions, immune deficiency, free radical damage, hormone problems, premature ageing, joint pain, low energy levels, slow digestion, and yeast/fungal infections.

To help the body neutralise an acidic diet, nutritionists recommend taking mineral supplements that include magnesium and calcium, eating more green foods, and plenty of water.

Some very alkaline foods include  watermelon, mango, papaya, asparagus, onion, vegetable juices, parsley, spinach, broccoli, and garlic.

Lemons, grapefruit, and limes although acidic also have an overall alkalising effect on the body.

Is Coca Cola a good rust remover?

You may have decided not to consume cola drinks any more.

So, what can you do with all the cans and bottles left in your cupboards?

Coke is a carbonated drink with a high sugar content, so it is very sticky, and therefore not a good cleaning product.

Additionally, the acid content is high, so although it will remove the rust, it can also tarnish the metal which isn’t so desirable either.

However, if you do have bottles of unwanted cola in your household, you can try it for the following household purposes:

  • Removing greasy stains and blood stains from clothes
  • Loosening rusty bolts
  • Cleaning oil from garage floors – let it soak, then hose off
  • Kills slugs and snails
  • Cleans burnt pans – let it soak then rinse off
  • De-scales a furred up kettle
  • Cleans car battery terminals
  • Cleans tile grout
  • Removes chewing gum from hair
  • Removes or fades hair dye
  • Removes marker stains from carpets
  • Cleans a toilet (best use for it I think!)
