USE DISH SOAP
Squeeze around 5-7 drops of dish soap (dawn)into the toilet. Then let it sit there for 15-20 mins. Then add some warm water into the bowl and let it sit there. Give it some time and your toilet will begin to unclog.
Do the same thing I did with the dish soap except for this time just use 3 cups of vinegar.
This method isn’t really all that effective but you can still try. Just use the toilet brush to clean inside the drain and hopefully it helps to clear it.
Just pour around 1 cup of Drano max build-up remover into the bowl and let it sit there until your toilet is unclogged.
