When you put soap in the toilet, it will float to the bottom of the toilet because it is denser than the water.

After that, this will help soften and dissolve any waste material that could cause a clog in the toilet.

Also, it will unclog the toilet if it is clogged and loosen up the toilet to enable easy flushing. Furthermore, you get to see a bit of foam each time you flush after you put soap in the toilet.

Foam appearance during toilet flushing is always a result of remnant soap in the toilet system, which activates during flushing.

#1. How to Unclog a Toilet Using Soap?

It requires some time because it needs time for it to dissolve all the dirt and muck that’s clogging the toilet.

Hence, patience comes with it by exercising patience for the clog dissolving action to occur. 

Below are the process for unclogging the toilet with soap:

  • It would be best to have hand gloves, some pots of slightly hot water(that you can bare dipping your hand into), and dish soap.
  • Firstly, turn the water valve behind the toilet in a clockwise direction to prevent water overflowing. Turning the valve in a clockwise direction will automatically switch the water supply to the valve. 
  • Secondly, gently and slowly pour a pot of mildly hot water into the toilet bowl. Then, leave it for 15 minutes for the heat to sink in to begin the dissolving process. 
  • Thirdly, pour about 1 and ½ cups of dish soap into the toilet bowl. Afterward, allow the soap to dissolve the clogs and lubricate the pipes and barriers of the toilet for close to 15-20 minutes.
  • Then, gradually, slowly, and cautiously pour another pot of mildly hot water into the toilet bowl. After that, leave it to settle for another 15 minutes to let the hot water and dish soap work together. The heat from the hot water and the dish soap’s dissolving properties will combine to unclog the toilet successfully. 
  • Lastly, switch on the water valve by turning it counterclockwise. Then, proceed to flush the toilet to finish the unclogging process. However, repeat the whole process if the toilet does not unclog immediately.

Meanwhile, it is crucial to be careful when carrying out this toilet unclogging procedure to prevent splashing hot water on yourself.

Also, do not pour boiling water into your toilet to prevent cracking and destroying your toilet pipes.

Meanwhile, soap works effectively in dissolving oil and water waste materials which is why it can break down poop.

Also, soap has unique features that quickly dissolve water, oil, and semi-solid substances.

In addition, it has unique structural molecules (polar head and non-polar tail structures) and solubility, further promoting effective dissolving.

Meanwhile, poop comprises 75% water and 25% solid or semi-solid matter. Therefore, soap can easily break down poop with time due to feces’ mainly 75% water content.
