Garbage disposal smells like sewage! Best odor removal techniques

The garbage disposal is where you shred food waste into smaller pieces. Due to its work, some food debris and grease will stick on the sides.

As you continue using the appliance every day, it can lead to some foul smells, especially if you do not clean it. Sometimes the stench is so awful that you can compare it to that of the sewer. So, why does a garbage disposal smell like sewage?

The primary reason your garbage disposal smells like sewage is the food, grease, and oils in the appliance have not been disposed of well. Basically, the stench comes from rotting food. When the garbage disposal grinds waste into a slurry, it spreads on the inside of the cylinder chamber that contains grinding and spinning teeth. If you fail to remove the sludge after use, it will rot even more until it starts smelling like sewage.

How to get rid of sewer smell in a garbage disposal

If your garbage disposal smells really bad, you can use several techniques to remove the odor. Here are a few of them:

1. Clean the garbage disposal using water and dish soap

Cleaning with water and dish soap is one of the simplest yet effective techniques of removing rotten smell from your garbage disposal. Here are the steps to follow:

  • Boil some hot water and pour it into a container.
  • Place a steel or rubber stopper into the drain.
  • Fill the sink with hot water.
  • Add dishwashing soap.
  • Mix the liquids well.
  • Lift the stopper and run the garbage disposal.

The combination of hot water and dishwashing soap will wash away the slurry in the garbage disposal. It will work the same way as cleaning the dishes. The appliance will suck in the mixture and the soap and water will clean all the waste stuck on the grinding and spinning teeth.

2. Clean it using vinegar and baking soda

A mixture of vinegar and baking soda for smelly garbage disposal offers a non-toxic option of eliminating the odors in the appliance. It also breaks down the leftover food particles stuck in the grinding and spinning teeth. For the best results, use white vinegar. You can view its price here.
