Do you know that you can actually unclog a toilet using common household items without the help of a plunger or snake?

A clogged toilet can be a very difficult problem to deal with. Homeowners who do not keep a plunger handy, will oftentimes find themselves in a huge inconvenience. But with the help of two simple household items, you might actually be able to get rid of the clog without having to use a plunger and without the help of expensive drain cleaning products.

Vinegar and baking soda are natural cleaning agents, when combined together, they can actually produce a chemical reaction that you can use to your advantage. Used frequently in volcano experiments by elementary students, one can actually use the fizzing reaction produced to release stubborn clogs from your drain and toilet.

If you have used these two items to unclog a sink, the same principle will be used for the toilet. You need however, to make sure that both ingredients are measured precisely, and that the reaction will stay within the toilet bowl.

Here’s what you need to do.

See how stubborn the clog is and start measuring

You need to check how bad the clog is. For minor clogs, you can use equal parts of baking soda and vinegar. Prepare the ingredients ahead of time. For minor clogs, prepare the full amount of baking soda and vinegar so you can use them all at once. For severe clogs, you can use smaller amounts of both items in several increments. Just make sure that you measure the ingredients carefully and that you try your best to avoid having an overflow.

Put baking soda into the toilet first

For minor clogs, you can pour the full amount of baking soda into the toilet bowl. For severe clogs, you can use ¼ cup of baking soda first and then increasing it to ½ cup after.

Pour the vinegar

Depending on how much baking soda you used, you now need to pour the exact same amount of vinegar into the toilet. Take note that as soon as you do so, the fizzing action will immediately begin.

Although the fizzing will begin and end quickly, you need to let both items work together by allowing it to sit for a few minutes before you go to the next step.

A kettle of hot water

After a few minutes, you can then pour a kettle of hot water into the toilet. This will help you see if the clog has now been released.


If the clog is still there, you need to repeat the previous steps. In most cases, you will hear the clog release with a quick suction sound. If the clog has been released, you need to flush the toilet at least two times more so you will know that the toilet is now back in order.

If the toilet does not unclog after repeating the process again and again, you may need to hire a plumber to deal with this problem for you.

Safety reminder: Please take note that you should never pour vinegar or baking soda into the drain before or after using Drano or any other drain cleaners.
