Are you experiencing an unpleasant odor in your kitchen that won’t go away? The culprit might be closer than you think – your kitchen sink. Drain Express delves into this common household issue

The Root Cause of Sink Smell

Your kitchen sink, a central plumbing feature, may harbor odors due to improper disposal of food and grease. These substances can get trapped in the pipes, leading to decomposition and unpleasant smells.

Grease Buildup in Drains

Pouring cooking grease or vegetable oil down the drain creates a residue that traps debris and emits a foul odor. To combat this:

  • Pour a cup of baking soda then, followed by vinegar, into the drain.
  • Let it sit for ten minutes.
  • Boil a pot of water and pour it down the drain to flush out the residue.

Dirty Garbage Disposals

Food scraps caught in garbage disposal blades can rot and smell. To clean:

  • Run cold water and the disposal for 20 seconds.
  • Add two cups of salt and a cup of ice to the disposal.
  • For extra freshness, use citrus rinds or lemon juice and vinegar.

Issues with the Kitchen P-Trap

A sewer-like smell could indicate a problem with the kitchen sink’s trap. Ensure the trap is filled with water to block sewer gases. If the smell persists, clean the trap thoroughly.
