How to Unclog Toilet with Baking Soda and Vinegar?

It is a known fact that blocked toilets create a lot of inconveniences. It becomes even more frustrating and annoying when you don’t have a plunger to clear this mess. What to do in this kind of situation? 

When you can’t find a plunger or an auger, you can unclog the toilet with kitchen chemicals i.e. baking soda and vinegar. Baking soda and vinegar are natural chemicals that react to form carbon dioxide, water, and pressure. This helps to clear the soft toilet blockages. To make this solution more effective, we often add hot water to the bowl.

Further, in this article, we will get to know in detail the complete procedure of unclogging a toilet with baking soda and vinegar.

Unclogging the Toilet with Baking Soda and Vinegar [4 Simple Steps]

Before we discuss this method, note that it is only effective if you have a soft stoppage. That means it won’t clear something that was accidentally flushed down the toilet such as a children’s toy or a solid phone. In case, you have a foreign object that is lodged in the toilet, this method won’t work.

Items You Need to Unclog the toilet

In this particular home remedy, you will need to grab a few items.

  • A cup of baking soda and vinegar
  • A Kettle full of hot water
  • Gloves and Mask (optional)

Step 1: Add a cup of Baking Soda to the toilet

Start by sprinkling the baking soda directly into the toilet bowl. Pour at least one full cup of baking soda. Using more than a cup won’t hurt anything; if you want to add more, that’s just fine.

Step 2: Add a Gallon of Hot Water

Heat water a gallon of water in a kettle till it starts boiling. Then pour the water into the toilet bowl. At this step, the water and heat may dissolve the clog. However, that’s not always the case. If the water starts to drain slowly, and you see the blockage clearing, then that’s fine. Otherwise, you need to move to the next step.

Step 3: Pour two cups of vinegar into the toilet

Start pouring vinegar directly into the toilet bowl. You will notice the ingredients working together and creating a fizz. The fizzing is due to the chemical reaction between vinegar and baking soda. Stop pouring if fizziness gets too high. However, it is the vigorous reaction between these two chemicals which dissolves the clogs and clears the toilet.

Step 4: Leave the Vinegar & Baking Soda Mixture

Allow the ingredients to work by letting them sit for about 2 hours. This passing time also allows the chemical reaction to complete. However, in some cases, you start to see results in a few minutes.

Once you see that the water level starts dropping, flush the toilet twice or thrice. The pressure will force the clog to drain out.

How do Vinegar and Baking Soda Dissolve Clogs?

Baking soda and vinegar are a terrific duo for cleaning out grit, filth and opening toilet clogs. This is because each material has its unique cleansing capabilities.

Baking soda, our kitchen staple, is made of a naturally occurring mineral, sodium bicarbonate. Being basic in nature, it may dissolve acidic mineral deposits and organic substances such as grease.

Vinegar is also a common kitchen item. It is chemically composed of acetic acid and water. Acids are very good at dissolving various substances in them. However, acetic acid is not very strong; its dissolving power is limited. That is why it is used in conjunction with baking soda.

Now, when vinegar (acetic acid) and baking soda (sodium carbonate) react in the toilet bowl, carbon dioxide and water are produced. The reaction is vigorous and produces carbon dioxide and water. You would see the formation of bubbles in water as a result. Furthermore, a lot of pressure is produced which forces the clog to clear.

Advantages of Using Baking Soda Vinegar Duo

Now, let’s talk about a few advantages of using this chemical duo.

  • Homebased Products: Both of them are home-based products and are easily found in our kitchens. Vinegar is something you use in most cooking meals.
