How To Clean A Garbage Disposal Safely And Effectively

A garbage disposal is an indispensable kitchen appliance that efficiently shreds food waste into smaller pieces, making it easier to flush down the drain.

Keeping your garbage disposal clean is essential to ensure its longevity and optimal performance.

In this article, we will walk you through the steps on how to clean a garbage disposal effectively and safely, along with some tips for maintenance and troubleshooting common issues.

Understanding The Garbage Disposal

What Is A Garbage Disposal?

A garbage disposal, also known as a waste disposal unit, is a motorized kitchen appliance installed under the sink. It is designed to break down food waste into tiny particles, allowing it to flow through the plumbing system without causing clogs.

How Does A Garbage Disposal Work?

The garbage disposal unit is equipped with sharp rotating blades or impellers that grind and shred the food waste. When you turn on the disposal, the impellers begin to spin rapidly, chopping up the food waste that comes into contact with them.

Safety Measures Before Cleaning

Before you start cleaning your garbage disposal, it is crucial to prioritize safety. Here are some essential safety measures to follow:

  • Turn Off And Unplug The Garbage Disposal: Before attempting any cleaning, make sure the disposal unit is switched off and unplugged to prevent accidental activation.
  • Use Safety Gloves: Wear protective gloves to shield your hands from potential cuts or abrasions.
  • Avoid Harsh Chemicals: Refrain from using harsh chemicals that can damage the garbage disposal or harm the environment.
  • Use Proper Tools: Use appropriate tools for cleaning to avoid damaging the disposal unit.

4. Freshen With Citrus Peels

Drop a few citrus peels, such as lemon or orange, into the garbage disposal. The natural oils from the peels will leave a pleasant scent and help combat any lingering odors.

5. Clean With Baking Soda And Vinegar

Pour half a cup of baking soda into the disposal, followed by one cup of white vinegar. The mixture will create a foaming action that helps remove grime and neutralize odors. Let it sit for a few minutes before rinsing it with cold water.

6. Disinfect With Bleach

If your garbage disposal still has persistent odors, you can disinfect it by pouring a mixture of one tablespoon of household bleach and one gallon of water into the unit. Let it sit for a few minutes before rinsing thoroughly.

7. Use Commercial Garbage Disposal Cleaners (Optional)

If you prefer a commercial cleaning solution, various garbage disposal cleaners are available in the market. Follow the instructions on the product label for safe and effective use.

Maintaining A Clean Garbage Disposal

To maintain clean and odor-free garbage disposal, follow these tips:

  • Run Cold Water: Always run cold water while operating the disposal to prevent fats and oils from solidifying and causing clogs.
  • Avoid Fibrous Foods: Refrain from putting fibrous foods like celery, onion skins, or corn husks into the disposal, as they can jam the blades.
  • Regular Cleaning: Clean your garbage disposal at least once a week to prevent buildup and keep it in top condition.

Troubleshooting Common Garbage Disposal Issues

1. Garbage Disposal Is Not Turning On

Check the power connection and reset button if your garbage disposal is not turning on. If it still doesn’t work, there might be an electrical issue, and you should contact a professional.

2. Garbage Disposal Is Making Strange Noises

Strange noises may indicate that there is something stuck in the disposal. Turn it off, unplug it, and try to remove the obstruction with tongs or pliers.

3. Garbage Disposal Is Draining Slowly

A clog in the drainpipe may cause slow-draining disposal. Use a plunger or a drain snake to clear the blockage.
