why does my kitchen sink smell bad and what can i do about it?

Try pouring baking soda and vinegar down it.

Good luck!

I am guessing it has some old food trapped in the pipes or garbage disposal…..Try filling the sink with hot water and Pine Sol then drain or turn on the garbage disposal…..good luck

If you have a garbage disposal, run some lemon wedges and ice cubes down it from time to time. The lemon clears the smell and the ice keeps the disposal blades sharp

Yes,try to grind some of the orange feel it may help

Other than the other answers about disposal smell inside, I would check to see if there are any leaks, becuase sinks start to smell when you have a small leak somewhere even up to the coupler that goes through the wall or floor. Check all your pipes very carefully with a flashlight and dry paper towell. Also check the floor inside the cabinet, If you have cabinets around your sink, there may also be something like a dead mouse between the cabinet floor and the real floor…

Pour some diluted clorox down disposal while running. then flush with water.
