Will a toilet eventually unclog itself?

Because most of the things that clog a toilet are water-soluble, eventually your toilet should unclog itself. However, it could take anywhere from a few hours to a few days, so you may want to speed up the process. A simple way to do that is to pour 1 cup (240 mL) of baking soda, 1 gallon (3.8 L) of boiling water, and 2 cups (470 mL) of white vinegar into the toilet. Let the mixture sit for at least 2 hours or as long as overnight. Then, take a plunger, place it over the hole in the toilet bowl, and give it a few good plunges. When you hear a suction noise and see the water level lowering, then flush the toilet. That should clear the clog and allow you to use your toilet.
