If you stay in a property long enough you will run into a very common problem that most household will have to face at least few times in their lifetime, a clogged drain!
One simple remedy is to first take a 1/4 cup of baking soda and pour it in the drain. 2nd pour 1 cup of vinegar. Pour it in the drain and cover & wait 15 minutes, and then rinse with hot water.
This is more envirnomently friendly. Baking soda is not harmful to the envirnoment.
