What Causes Kitchen Sink Smell?

Food Is The Main Reason Causes Sink Smell

The kitchen sink, arguably the dirtiest spot in the house, is frequently overlooked. Food particles become stuck in the drain, producing an unpleasant stench to rise. 

Grease or fat accumulation in the drain might potentially be causing the moldy or rotten egg odor. The odor is revolting, and you will want to get it out of the kitchen as quickly as possible. 

Thankfully, there are several options for getting rid of that noxious odor. To keep your kitchen smelling clean and fresh, try these workable tricks.

6 Ultimate DIY Ideas: How To Get Rid Of Kitchen Sink Odor?

1. Use soapy water to soak the sink

A food deposit accumulated on the sidewalls or base of the sink after leaving dirty dishes in the kitchen sink for too long can cause sink odors. 

It would be best if you soaked the sink to get it sparkling clean and smell-free: Fill the sink full with warm water and one teaspoonful of dish detergent, then place a sink plug in the drainage. 


To release the food debris, swirl the liquid of the basin with a rubber glove until the detergent has fully dissolved, then leave the solution for 15 minutes. Next, pull out the sink stopper and switch on the trash disposal to discharge the loose debris down the drain.

2. Remove any clogs from the trash disposal fans or the drain

If your kitchen sink continues to stink, look for a hard food scrap or dropped utensil in the drainage. Utensils may trap food particles and avoid them going through the trash compactor if they become caught in the pipe or between the fans of the disposal. 

These trapped foods release smells if not removed before they decay. Unplug the trash disposal before eliminating these obstacles. Do not let the garbage start running when your hands are in the sink! 

Then, using a flashlight, search through the lengths of the drain pipe for any blockages around the disposal unit’s rotors at the top. If you come across something, carefully remove it using needle-nose pliers.

3. Use vinegar and baking soda

Use Baking Soda And Vinegar To Get Rid Of Sink Odor

With each disposal, the sidewalls of the drain can gather tenacious oil and dirt. While a bristles brush won’t reach all the drain, a mixture of white vinegar and baking soda will help scrape away the muck. 

Set aside a pot of water that has been brought to a boil. Meanwhile, add one baking soda cup into the drain, followed by a vinegar cup. Allow five to ten minutes for the mixture to effervesce in the sink, then pour the hot water down the drain. 

The astringent vinegar, abrasive baking soda, and hot water scrub the drain walls together. To remove any leftover baking soda, open the cool water for a minute.

4. Scrub the flange of the sink

The metal sink flange, which connects the trash disposal to the drain, is a frequent collection point for food waste. Because it is hard to wipe away, scrubbing is required to eliminate it. 

To begin, disconnect the trash disposal system from the wall. After that, squeeze some dollops of liquid soap onto the head of a dish brush, lightly dampen the brushes with tap water, and scrape the top of the flange with the wand lowered into the drain pipe. 

Run the water tap for thirty seconds after cleaning the sink flange and flush out any loose debris.

5. Using salt and ice, clean the disposal impeller plate and blades

Food waste can build and eventually produce an unpleasant odor because the trash disposal blades and the revolving impeller plate are all engaged in mashing food. 

Drop two ice cubes and one salt cup down the sink drain to sanitize the impeller plate and blades. Turn on the garbage disposal while the water tap is flowing until the ice thoroughly melts.

Any food waste and residue on these two parts should be unfastened and lifted by the absorption of salt and ice. The food residue—along with its foul odor—goes down the drain.

6. Use citrus fruit peels to deodorize the waste disposal

Citrus Fruit Peels 

Occasionally, crushed food particles struggle to exit the disposal and become trapped on the walls. As a result, they decay in the basin and emit an awful stench. 

Citric acid, which may be found in the peels of lemons, oranges, and citrus, dissolves food residue from the sink drain walls and masks an unpleasant stench with a sweet scent. 

To do so, release the acid, drop a few citrus peel fragments into the drain and spin the trash disposal for thirty seconds.
