5. Pour salt down your drain
Let’s start with the simplest of simple home remedies: Salt won’t unclog stubborn clogs, but it will neutralize bad odors. And that’s sometimes all that matters.
To do this, put two tablespoons of salt down the drain and wait half an hour to an hour for the salt to work. Then rinse with cold water. This not only helps with current odors, but also prevents repeated odor formation.
