A garbage disposal is a handy appliance in any clean kitchen, as it helps to quickly and efficiently dispose of food waste. However, without proper maintenance and regular cleaning, a garbage disposal can become a breeding ground for unpleasant odours and even blockages. So let’s dive in and learn how to keep your garbage disposal clean and fresh.

1. Understanding Your Garbage Disposal: Components and Operation

In order to effectively clean and maintain your garbage disposal, it’s crucial to have a solid understanding of its components and how it operates. By familiarizing yourself with the various parts and their functions, you’ll be better equipped to handle cleaning tasks and ensure the optimal performance of your garbage disposal.

Motor Unit: The motor unit is the powerhouse of the garbage disposal. It consists of an electric motor that drives the grinding blades. When you turn on the disposal, the motor spins the blades at a high speed, enabling them to break down food waste into smaller particles.

Grinding Chamber: The grinding chamber is the area where the actual grinding of food waste occurs. It houses the spinning blades that shred and pulverize the waste into fine particles. The grinding chamber is typically made of durable materials such as stainless steel to withstand the rigours of the grinding process.

Drain Connection: The drain connection is the point where the ground food waste is flushed out of the garbage disposal and into the sewer system. It connects the disposal unit to the kitchen drainpipe, allowing the waste to flow away.

Understanding these components will help you navigate the cleaning process more effectively. For example, knowing that the motor unit contains electrical components will remind you to disconnect the power supply before attempting any cleaning or maintenance tasks. Similarly, being aware of the grinding chamber’s location and function will allow you to target your cleaning efforts in that specific area.

2. Safety Precautions

Cleaning a garbage disposal requires certain safety measures to protect yourself from injuries. Here are some important precautions to keep in mind:

Disconnect the power: Always start by disconnecting the power supply to the garbage disposal. This can be done by either unplugging it from the electrical outlet or turning off the circuit breaker that supplies electricity to the disposal.

Avoid using your hands: Never attempt to clean the garbage disposal with your hands. The grinding blades are sharp, and there may still be residual food waste that could cause injury. Always use appropriate tools and utensils for cleaning.

Use protective gear: Consider wearing rubber gloves and safety glasses to protect your hands and eyes from any potential debris or splashes during the cleaning process.

3. Cleaning Process

Now that we have covered the safety precautions, let’s move on to the step-by-step cleaning process:

Remove visible debris: Start by inspecting the garbage disposal and removing any visible debris or large food particles. Use a pair of tongs or pliers to carefully extract any objects that may have fallen into the disposal.

Create a cleaning solution: Prepare a mixture of equal parts white vinegar and baking soda. This combination creates a powerful yet natural cleaning solution that helps to remove grime, grease, and unpleasant odours.

Pour the cleaning solution: Carefully pour the vinegar and baking soda mixture into the garbage disposal. Allow it to sit for about 15 minutes to break down any stubborn residue.

Scrub the grinding chamber: After the solution has had time to work, take a long-handled brush or an old toothbrush and gently scrub the inside of the grinding chamber. Pay special attention to the rubber flaps and crevices where food particles tend to accumulate.

Flush with hot water: Once you have thoroughly scrubbed the grinding chamber, turn on the hot water faucet and let it run for a few minutes. The hot water will help flush out any remaining debris and ensure a clean and fresh-smelling disposal.

Deodorize with citrus peels: To eliminate any lingering odors, drop a few citrus peels (such as lemon or orange) into the garbage disposal. Run cold water and turn on the disposal for a few seconds to grind the peels. The natural oils in the peels will leave a refreshing scent in the disposal.

4. Maintenance Tips

Cleaning your garbage disposal regularly is essential, but there are also some maintenance tips that can help prolong its lifespan and prevent issues:

  1. Avoid fibrous and starchy foods: Fibrous foods like celery and starchy foods like potato peels can clog the disposal. Dispose of these items in the regular trash instead.
  2. Run cold water before and after use: Always remember to run cold water for a few seconds before and after using the garbage disposal. This helps flush away any small particles and keeps the disposal clean.
  3. Sharpen the blades: Occasionally, you can sharpen the garbage disposal blades by running a few ice cubes through the unit. The ice helps to remove any buildup on the blades and keeps them sharp for efficient grinding.
  4. Use it regularly: Regular use of the garbage disposal helps prevent rust and corrosion. If the disposal is not used frequently, it can lead to unpleasant odors. So make sure to run it every few days, even if there’s no significant food waste.

5. Troubleshooting Common Issues

Despite regular cleaning and maintenance, you may encounter some common issues with your garbage disposal. Here are a few troubleshooting tips:

  1. Disposal is jammed: If your disposal is not working or making a humming noise, it might be jammed. Turn off the power and use a disposal wrench (or an Allen wrench) to manually rotate the blades and dislodge any trapped objects.
  2. Foul odours persist: If unpleasant odours persist even after cleaning, consider using specialized garbage disposal cleaning tablets or pods. These products are designed to break down residue and eliminate odour-causing bacteria.
  3. Excessive noise or vibration: Excessive noise or vibration during operation may indicate loose or damaged components. In such cases, it is advisable to call a professional plumber to inspect and repair the disposal.


Cleaning a garbage disposal doesn’t have to be a daunting task. By following the steps outlined in this article, you can clean your garbage disposal like a pro, ensuring its optimal performance and preventing any potential issues. Remember to prioritize safety, use the proper cleaning techniques, and maintain the disposal regularly to keep it clean, fresh, and efficient. With proper care, your garbage disposal will continue to serve you well for years to come.
