How do I clean a smelly bathroom sink drain?

What can I use to clean my smelly bathroom sink drain and get rid of the smelly odor from the bathroom sink drain?

Answer 1

You can get rid of bathroom sink drain smells by pouring some warm white distilled vinegar down the sink drain along with some baking soda until it bubbles.

Next get some water boiling in a  kettle or pan or whatever you have to get the water boiling in and pour the boiling water down the bathroom sink drain while the Vinegar and baking soda is bubbling.

This should stop the bathroom sink drain from smelling.
