Before you unclog the particles, follow this guideline to ensure safety and a rewarding outcome.

  •  Get rid of the food particles with tongs or pliers
  • You can now plug the disposal back in
  • Run a sufficient amount of water.

2. Flush the garbage disposal with hot water

If running the garbage disposal with cool water is not enough, try running the garbage disposal with hot water. Perceiving bad smell from the insinkerator is what you should not let linger for another day.

The garbage disposal is often clogged with food crumbs and would need a bit of push for the pipe to clear the clogs.

So, if your insinkerator smells terrible and you do not know how to get rid of it, the second thing you need to do is use hot water to flush the disposal so it releases the food particles.

3. Soak your disposal in soapy water

Do you want your disposal to smell nice again? Then soak the removal in soapy water. There is no better way to eliminate a foul smell than using good soapy water. Provided the detergent you used exudes a compelling fragrance, your disposal would smell nice again.

  • Plug the disposal drain
  • Depending on the size of the garbage disposal, fill the sink with 4 to 6 inches of water. Add two teaspoons of liquid dish detergent
  • Create suds by mixing the water with the soap
  • Let the soapy water sit in the disposal for sometime
  • Turn the disposal on and allow it to run for sometime
  • Turin of the disposal when you satisfied with the outcome
  • Use a brush to scrub off stubborn particles. Scrub the outside part of the disposal too
