How to Clean a Garbage Disposal

Cleaning your garbage disposal regularly is crucial for keeping your kitchen fresh and avoiding clogging or odors. Here’s a step-by-step guide to help you:

Materials You’ll Need:

  • Garbage disposal cleaner (or household alternatives)
  • Ice cubes
  • Salt
  • Citrus peels
  • Baking soda and vinegar
  • Dish soap
  • Soft scrub brush

How to clean garbage disposal?

Step 1: Disconnect the Power

Before cleaning your sink disposal, ensure it’s turned off or disconnected from the power source. Safety first!

Step 2: Clean the Splash Guard

The splash guard (the rubber flaps at the opening of the sink garbage disposal) often traps food and grease. As a result, if you don’t wash the splash guard, you may get a foul odor. To clean it: 

  • Use a soft scrub brush or toothbrush.
  • Apply dish soap and scrub the underside thoroughly.

Step 3: Remove Visible Debris

Shine a flashlight into the garbage disposal and use tongs or pliers to carefully remove any large pieces of food or debris stuck inside. Avoid using your hands to prevent accidents.

Step 4: Pour in Baking Soda and Vinegar

To neutralize bad odors, create a simple garbage disposal cleaner using common household ingredients:

  • Pour ½ cup of baking soda into the disposal.
  • Follow up with 1 cup of vinegar.
  • Let the mixture fizz for a few minutes before rinsing with hot water.

This combination helps break down grime and naturally deodorize your sink garbage disposal.

Step 5: Clean the Blades with Ice and Salt

Grinding ice cubes and coarse salt can help remove grease buildup and sharpen the blades of your garbage disposal. Here’s how:

  • Fill the disposal with a cup of ice cubes.
  • Add ½ cup of coarse salt.
  • Turn on the garbage disposal and run cold water.

This helps clean the blades, removing stubborn food particles that regular rinsing may miss.

Step 6: Freshen the Disposal with Citrus Peels

To give your garbage disposal a fresh smell, run a few citrus peels (like lemon or orange) through the unit. The natural oils in the peels help eliminate lingering odors and leave a pleasant scent.

Step 7: Regular Maintenance

Regularly cleaning your garbage disposal will extend its lifespan. Use a garbage disposal cleaner or natural cleaning solutions like baking soda and vinegar monthly to maintain cleanliness. If you notice performance issues, you may need to check for clogs or obstructions.
