Full Answer

Determining how to remedy a smelly drain depends greatly on the specific cause. Running hot water down the drain is a good remedy for food that is lodged in the garbage disposal, as the hot water helps to dislodge the food as well as kill the bacteria that is causing the odor. Additional natural remedies include baking soda and lemon juice.

For kitchen drains that are mildly clogged, there are over-the-counter drain cleaners that safely dissolve grease and debris build up. If home remedies and over-the-counter products do not remove the smell, homeowners can call in a professional. Backed up sewer gas smells like rotten eggs emitting from the drain, and it can quickly lead to a more serious plumbing issue. Professional plumbers have special cameras and equipment that travel deep into the drain pipes, allowing for an accurate assessment of the issue and quick repair.
