5 Things You Should Never Mix With Vinegar When Cleaning

This post contains affiliate links.

Many online natural cleaning recipes frequently advise you to mix vinegar with other ingredients.

This may encourage you to do a little bit of experimenting of your own. 

When this happens, you run the risk of turning perfectly harmless ingredients into a potentially deadly cocktail or, at best, a useless sludge.

With this in mind, here is my list of five things you should never mix with vinegar when cleaning… 

Points 1 & 2 have lengthy explanations attached to them as they are touted heavily by many websites. However, in my experience, I find their advice misleading.

1. Baking Soda – Never Mix With Vinegar When Cleaning

The two most popular online recipes requiring you to mix these two ingredients are a multipurpose spray cleaner and an effective drain cleaner.

Unfortunately, both of these recipes are not your best cleaning options, and here’s why…

Look out, here comes the science stuff!

When baking soda and vinegar are mixed, hydrogen ions in the vinegar react with the sodium bicarbonate ions in the baking soda and start a chemical reaction.

This initial reaction is the formation of two new chemicals: Carbonic acid and Sodium acetate. Carbonic acid is what you find in most fizzy drinks, and it is the fizzing reaction that is unblocking your drains.

Like the carbon dioxide bubbles found in fizzy drinks, the carbon dioxide bubbles that form result from the carbonic acid decomposing into water.

This bubbling gas then rises to the top of the mixture and is evidenced by the fizzing and frothing you see and hear. (It is this action that displaces the blockage in your drains).

The result of this visually explosive chemical reaction is water (H2O) and sodium acetate (C2H3NaO2).

Consequently, the net result of all this activity is a solution of foul-tasting salty water.

Not a natural household multipurpose cleaner as advertised. However, many people refuse to see the natural chemistry at work.

Now, who would want to clean down all their surfaces with slightly salty water? 

So, What Should We Be Doing?

The simple truth is that you are far better off using a neat or 50/50 mix of vinegar and water.

Simply spray this onto a cloth, and apply this to the surface to be cleaned.

This stronger recipe will sterilize the surface and begin breaking down the light grease deposits.

Once done, you can then apply the baking soda as the abrasive and finish by rinsing off the residue with a damp cloth. 

However, this may leave a white residue and is still less effective than using a multipurpose cleaner that includes Castile soap.

If you are going to use vinegar and baking soda, then that is the way you should be doing it. 

However, a lot of online gurus don’t give you this information. Instead, they tend to follow the flow of everyone else’s advice and refuse to do any practical research of their own. 

For me, the truth is that baking soda and vinegar react chemically because one is a base, and the other is a weak acid.

This means that when they are brought together, they immediately begin canceling each other out.

(Basic schoolboy science).

2. Castile Soap – Never Mix With Vinegar When Cleaning

Another much-touted recipe for natural homemade cleaners that I see very often puts the soap and vinegar together sharing the same container.

This is never a combination that works well, and if you were wondering why not, then here’s the reason why.

Lookout, another science bit coming up!

Vinegar is an acid, and castile soap is a base. So when you mix them, the great grease-cutting ability of the soap and the vinegar’s disinfectant quality are canceled out by each other.

Moreover, the vinegar has “unsaponified” the soap, which means it is reduced back to its original oil composition.

What you have in your bottle is an oily curdled mess.

This mixture then clogs the spray or cloth you are using and leaves a deep claggy coating over whatever it is you attempt to clean.

How To Clean With Vinegar And Soap

A far better way to use these two items is to use a Castile soap-based multi-surface cleaner to remove the grease.

Once done, wipe down with a damp cloth and then use a vinegar solution to disinfect the cleaned area.

This is a superior method to the neat, or 50/50 mix, followed by a damp cloth wipe-down method mentioned at the beginning of this post.

Many cleaning tasks can be completed this way, but please always use them separately and don’t mix them.

Alternatively, use Sal Suds. Unlike Castile soap, Sal Suds is a detergent and can be combined with vinegar.

This is achievable because it has a different chemical composition compared to Castile soap.  

One word of warning is that Castile soap becomes “unsaponified” whenever it comes into contact with acids. So please check that your essential oils or other additives are plant-based and not juice-based.

3. Hydrogen Peroxide – Never Mix With Vinegar When Cleaning

Vinegar and hydrogen peroxide are both effective disinfectants, so what happens when the two are combined?

A combination of vinegar and hydrogen peroxide produces peracetic acid.

Peracetic acid is highly corrosive, and although its toxicity is relatively low, it can still cause irritation to the throat, skin, eyes, and nasal membrane.

It is a highly effective bleach for these reasons.

But to be honest, it is far safer for you to keep these two ingredients apart.

4. Bleach – Never Mix With Vinegar When Cleaning

 As I have already demonstrated in this article, it is never a good idea to mix your cleaners, or as my old chemistry teacher used to say…

“Chemistry is an insane thing, and what you don’t know could kill you!”

Never has this been more true than when you mix vinegar and bleach.

The effect of mixing these two products is the production of chlorine gas.

This gas is a killer, and here’s why!

Chlorine gas was first used on the infamous day of April 22, 1915, in WW1

It produces a greenish-yellow cloud that smells of bleach and immediately irritates the eyes, nose, lungs, and throat of those exposed to it.

It kills by asphyxiation at high enough doses, so never mix vinegar and bleach under any circumstances.

vinegar + Bleach = Toxic Chlorine Gas.  

5. Bleach, And Water – Never Mix With Vinegar When Cleaning

Vinegar + Bleach + Water = Hydrochloric and Hypochlorous acids.

Foul-smelling and bad for clothing.

The chemical substance of Hydrochloric acid is the aqueous (water-based) solution of Hydrogen Chloride gas.

It is a strong, highly corrosive acid, clear in color with a strong, pungent smell.

It is also the major component of gastric acid, which is naturally produced by cells in the human body to aid digestion.

When vinegar, bleach, and water are mixed in a washing machine, Hydrochloric and Hypochlorous acids are formed.

These acids may be weak due to the large water content in the machine, but they still have the potential to be dangerous.

Both of these acids are foul-smelling and corrosive, therefore direct contact should be avoided.

In summary

Next time you feel like mixing things to see what happens, remember this post, then stop and reconsider your actions.

THE RESULT MIGHT NOT BE THE ONE THAT YOU EXPECT!
