How to stop kitchen sinks from smelling
Even the cleanest sinks can develop drain odours. (evier image by Charly from

Over time, kitchen sink drains can accumulate food residue and particles that do not wash away with soap and water. The food build-up attaches itself to the pipe itself and remains there, often causing an offensive odour. While it may be tempting to use commercial drain cleaners to remove the smell, it often will not work because the drain cleaners are formulated to run down to a clog and sit there, passing up smelly food particles on the way. There is a natural way to deodorise your drain with items you probably already have at home.

Skill level:

Things you need

  • Measuring cup
  • Baking soda
  • White distilled vinegar

  1. 1

    Rinse out your sink so that any food residue is removed from the sink itself.

  2. 2

    Pour 307 g (1 cup) of baking soda into a measuring cup and pour it directly into your drain.

  3. 3

    Fill the measuring cup with 437 ml (1 cup) of white distilled vinegar and pour it into the drain as well. The vinegar and baking soda both have deodorising and cleaning properties. When they are mixed, they foam up to break down the food residue in the drain.

  4. 4

    Allow the foam to sit in the drain until it starts to recede. Rinse it down the drain with cool water. You will notice a vinegar smell in place of the food smell, but it will dissipate within a couple of days and your drain will smell clean and fresh.

Tips and warnings

  • Add this drain cleaning process to your monthly chore list so that you can maintain you fresh smelling drain.
