The Baking Soda Method
Baking soda is a must-have at home. In addition to its cleaning properties which no longer need to be proven, it is also an ally of choice in the fight against traffic jams. To use it, heat water, without boiling, and add half a cup of baking soda. For even more effective results, add half a cup of white vinegar to the mixture. Pour everything into the clogged toilet and lower the lid. The whole thing should create completely harmless foam for a few minutes. Come check in from time to time. Once the water level has dropped, flush and wash your toilet to remove all traces of baking soda from the walls.

The lemon juice method
Powerful degreaser and formidable antibacterial, lemon is perfect for this exercise. Likewise, citric acid, which contains the power of almost 10 lemons, also does the job very well. It is particularly useful if tartar is the cause of your clogged toilet. Pour a mixture of citric acid (or lemon) and baking soda into the bowl and let the magic happen. If all goes well, you should see the standing water become covered in bubbles. Exactly as with the method above, let the products act and the water level drop before flushing.
