Understanding Your Garbage Disposal

Before diving into the cleaning process, it’s helpful to understand a bit about how your garbage disposal works. Installed under your kitchen sink, garbage disposal grinds up food waste into tiny particles that can be flushed away through your plumbing. Over time, bits of food, grease, and other residues can build up inside the disposal and cause blockages or bad smells.

Why Regular Cleaning is Important

  1. Prevents Bad Odors: Food particles can get stuck in the disposal and decompose, causing foul smells.
  2. Maintains Efficiency: Regular cleaning helps ensure that your disposal continues to operate smoothly.
  3. Extends Lifespan: Proper maintenance can extend the life of your appliance.
  4. Prevents Clogs: Cleaning helps to remove build-up that can lead to clogs.

Materials You’ll Need

  • Dish soap
  • Baking soda
  • White vinegar
  • Ice cubes
  • Rock salt
  • Lemon or lime
  • A small scrub brush or old toothbrush
  • Rubber gloves

Step-by-Step Cleaning Process

1. Safety First: Turn Off the Power

Before you start cleaning your garbage disposal, ensure it is turned off. Unplug it from the outlet under the sink, or if it’s hardwired, switch off the appropriate circuit breaker. This is a crucial safety step to prevent accidental injuries.

2. Initial Rinse and Scrub

  • Rinse with Hot Water: Run hot water down the disposal for about a minute to loosen any grease or debris.
  • Scrub the Visible Parts: Use a small scrub brush or an old toothbrush with a bit of dish soap to clean the rubber splash guard. Pull the splash guard out slightly (most are removable) and scrub both sides. This area often harbors a lot of gunk.

3. Deep Cleaning with Baking Soda and Vinegar

  • Pour Baking Soda: Sprinkle half a cup of baking soda into the disposal.
  • Add Vinegar: Slowly pour one cup of white vinegar into the disposal. The mixture will fizz and bubble, which helps to break down the build-up.
  • Wait: Allow the mixture to sit for about 10-15 minutes. This gives the baking soda and vinegar time to work their magic.
  • Rinse: Rinse the disposal with hot water for a few minutes to flush out the loosened debris.

4. Ice and Salt Cleaning

Using ice and salt helps to sharpen the blades and remove any stuck-on residue inside the disposal.

  • Add Ice Cubes: Fill the disposal with ice cubes.
  • Add Rock Salt: Pour a cup of rock salt over the ice cubes.
  • Run the Disposal: Turn on the disposal and let it run for a few minutes with cold water. The grinding action of the ice and salt will clean the interior of the disposal.

5. Freshening with Citrus

Citrus fruits like lemons and limes can help to deodorize your garbage disposal naturally.

  • Cut Citrus: Cut a lemon or lime into small wedges.
  • Grind the Citrus: With the cold water running, drop the citrus wedges into the disposal one at a time and turn on the disposal. The citric acid in the fruit will break down grease, and the natural oils will leave a fresh scent.

6. Final Rinse

Finish the cleaning process by running cold water down the disposal for a minute or two. This helps to flush out any remaining debris and ensure everything is clean and fresh.

Tips for Maintaining Your Garbage Disposal

  • Run It Regularly: Even if you don’t have much to grind, run the disposal with cold water periodically to keep parts moving and prevent rust and corrosion.
  • Use Cold Water: Always use cold water when running the disposal. Cold water helps to solidify grease.
  • Avoid Certain Foods: Some foods should never go down the disposal, including fibrous vegetables (like celery), starchy foods (like potato peels), coffee grounds, and large bones. These can cause clogs or damage the disposal.
  • Grind Small Bones and Eggshells Occasionally: These can help to clean the disposal and sharpen the blades, but use them sparingly.
  • Flush with Cold Water: After each use, run cold water for at least 15 seconds to ensure all particles are washed away.

Signs Your Garbage Disposal Needs Attention

  • Persistent Odors: If smells linger despite regular cleaning, there might be trapped food particles you can’t see.
  • Slow Draining: This can indicate a clog in the disposal or the drain line.
  • Unusual Noises: Loud, unusual noises might mean something is stuck or there’s an internal problem.
  • Poor Performance: If the disposal isn’t grinding food effectively, it may need maintenance or repairs.

When to Call a Professional

If you’ve tried cleaning and maintaining your garbage disposal but it’s still not working properly, it might be time to call a professional. Persistent issues can indicate more serious problems that require expert attention.


Keeping your garbage disposal clean is crucial for maintaining a hygienic and efficient kitchen. By following the steps outlined above and incorporating regular maintenance into your routine, you can prevent unpleasant odors, avoid clogs, and extend the life of your appliance. Remember, safety first—always ensure the power is off before you start cleaning, and avoid putting your hands directly into the disposal. With a little effort and the right techniques, your garbage disposal will remain a reliable kitchen helper for years to come.
