In this article, I’ll take you through five simple steps to clean your garbage disposal and get rid of bad smells from your kitchen. You just need a few household items to start. Ready to freshen up your kitchen? Let’s dive in.

Why Does Your Garbage Disposal Stink Anyway?

What's that smell coming out of the sink ?

If you’ve ever noticed a bad smell coming from your garbage disposal, you’re not alone. It’s a common issue in many kitchens. The main culprits behind these unpleasant odors are usually trapped food particles and bacteria buildup. Here’s a closer look at why this happens:

  1. Trapped Food Particles: Every time you wash dishes or dump leftovers down the disposal, small pieces of food can get stuck in the blades. Over time, these tiny food pieces begin to decompose, which can lead to a pretty nasty smell.
  2. Size Matters: The size and power of your garbage disposal can play a big role in this. Smaller, less powerful, 1/3 horsepower disposals might save you money upfront but can get clogged more easily and struggle with tougher kitchen waste. On the other hand, 3/4 horsepower garbage disposer grinds food more finely and handles larger loads better, which helps prevent clogs and related smells.
  3. Bacteria Buildup: Kitchens are naturally a breeding ground for bacteria due to the moisture and organic material. Warm, moist environments like your garbage disposal are perfect for bacteria to grow. As these bacteria break down the food residues, they release foul-smelling gases.
  4. Lack of Cleaning: Regular cleaning is often overlooked when it comes to garbage disposals. Without routine maintenance, the combination of old food and bacteria can become overwhelming, and the smell can spread to other parts of your kitchen.
  5. Oils and Fats: Pouring oils and fats down the disposal is another no-no. They might go down as liquids, but they solidify as they cool, clinging to the sides of your disposal and pipes. This not only causes clogs but also contributes to unpleasant smells as these fats go rancid.

How to Clean a Garbage Disposal in 5 Steps

Cleaning your garbage disposal is straightforward and can significantly freshen up your kitchen. Here’s how you can do it in five simple steps:

1. Clean the Rubber Splash Guard

Start by turning off the power to your disposal at the circuit breaker to ensure safety. The rubber splash guard on top of the disposal tends to hold onto food particles and debris. Lift the flaps and use a small brush, such as an old toothbrush, dipped in soapy water to scrub underneath each flap. Make sure to rinse the splash guard well with water once you’re done scrubbing.

2. Wash Disposer with Hot, Soapy Water

With the power still off, fill the disposal with a mixture of hot water and dish soap. Let this sit for a few minutes to loosen any accumulated grime. Afterwards, turn on the water and briefly run the disposal to flush out the soapy mixture, helping to clean the interior surfaces.

3. Grind Ice Cubes and Rock Salt

To clean the grinding elements and sharpen the blades, fill the disposal with two cups of ice cubes followed by a cup of rock salt. Turn on the disposal to grind the ice and salt together. This process not only helps in removing the stuck-on debris but also sharpens the disposal’s blades.

4. Scour with Vinegar and Baking Soda

For a deeper clean and to deodorize, pour half a cup of baking soda directly into the disposal followed by a cup of white vinegar. The resulting fizzing action helps break down tough grime and neutralizes unpleasant odors. Let the mixture sit and work its magic for about ten minutes before flushing it down with hot water while running the disposal.

5. Freshen with Lemon Power

As a final step, freshen up your disposal by using lemon. Cut a lemon into quarters, ensuring the pieces are small enough to be safely ground by your disposal. With the disposal and water running, feed the lemon pieces into the unit. This not only helps clean your disposal further but also leaves a fresh, clean citrus scent in your kitchen.

FAQ’s

To eliminate garbage disposal smell, you can use a combination of ice and salt, baking soda and vinegar, or citrus peels. Start by running cold water and grinding ice cubes in the disposal to remove debris. For a deeper clean, pour half a cup of baking soda followed by a cup of vinegar down the disposal, let it fizz for a few minutes, then rinse with hot water. Citrus peels, like lemon or orange, can also be ground up in the disposal to leave a fresh scent.

To combat food waste smell, ensure you’re regularly removing and disposing of food scraps. For immediate relief, sprinkle baking soda in the bottom of your trash can or where the food waste is stored, as baking soda neutralizes odors. Using lemon peels or vinegar can also help. For long-term solutions, consider composting food waste to reduce the amount sitting in your trash.

First, turn off the power to the disposal at your circuit breaker. Disconnect the disposal from the drain pipe and the dishwasher inlet, if applicable. Support the disposal with one hand (they can be heavy) and use a wrench or a screwdriver to loosen the mounting ring that attaches the disposal to the sink.

To freshen your garbage disposal with lemon, cut a lemon into small pieces or wedges. With the water running, drop the lemon pieces into the disposal and turn it on. The grinding action will release the lemon’s natural acids and oils, cleaning the disposal blades and walls while leaving a fresh, citrus scent.
