by Ian Haynes

The kitchen is an area where you'll be cooking with fresh ingredients and making delicious meals; hence, it's vital to keep the kitchen area along with all of its equipment both clean and smelling fresh.  

The garbage disposal, in particular, is an area that you should be cleaning regularly. If you’ve noticed that your garbage disposal is smelling a little funky, this guide can help. Here, we’ll provide you with everything you need to know about how to make your garbage disposal smell better and more.  

Wondering why your garbage disposal is smelling bad? Here are the most likely causes:  

  • Decomposing Food And Grease  
    Even though garbage disposals are meant to help dispose of food down the drain, it doesn’t mean that you should be shoving all of your food down the garbage disposal. If you do, it’s possible that those food particles are decomposing while clogging up the pipes and producing a foul odor. 
  • Mold And Bacteria  
    While the top of your garbage disposal may look clean, it’s possible that the underside of the rubber section of your garbage disposal is growing mold. After all, a warm and moist environment is the perfect breeding ground for mold and bacteria.  
  • Sewer Gases Or Stagnant Water  
    All if not most sinks come with a trap that holds water and prevents sewer gases from rising out of the drain. If there are blockages within your vent or other problems with your vent, it could cause these sewer gases to seep into your kitchen. Stagnant water could also cause foul smells in your garbage disposal.

Homemade Solutions You Can Try (Pouring Down the Sink)  

To get rid of those nasty smells, here are some homemade solutions that you can try at home:  

Ice

Ice is great at getting rid of foul smells. As a bonus, ice can also help with sharpening the blades of your garbage disposal. It’s also something you don’t have to go out and purchase, as it’s likely that you’ve got plenty of ice at home. Simply fill your garbage disposal with ice, let your garbage disposal do its thing, and you should be good to go.  

Citrus

Another great homemade solution is citrus. Simply cut either a lemon, lime, or even an orange into small pieces and place them into the running garbage disposal. The fruit should help with washing away any foul odors and replacing it with a fresh citrus smell.

Vinegar and Baking Soda

You can’t go wrong with vinegar and baking soda. All you’ve got to do is turn on your garbage disposal before pouring down a cup of dry baking soda. Then, flush the baking soda away with a cup of distilled white vinegar. Wait for a little, and the foul smells should be gone.  

Bleach

If you're using bleach, make sure that it's a mild product and ensure that the water is running. Then, start by pouring just a little bleach down the garbage disposal as the cold water runs, and it should both erase the scent and help to dislodge any food particles that might be stuck in the pipes.  

Garbage Disposal Cleaning Products

5 Tips for Keeping Garbage Disposals Clean  

Here are a couple of tips on keeping your garbage disposal clean and preventing it from becoming smelly in the first place.  

  • 1. Clean your garbage disposal regularly  
    After you’ve used your garbage disposal, you should run it for at least five seconds until the grinding noise levels out. If you end up stopping the blades early, food will end up lodged in your garbage disposal and cause unpleasant smells. You should also occasionally (every two weeks or so) place ice cubes or lemon peels down your garbage disposal to keep it clean.  
  • 2. Avoid putting down certain foods   
    While it might be tempting to shove everything down the garbage disposal, certain foods are not suited for the garbage disposal. Such foods include potato and carrot peels, grease, coffee grounds, and eggshells. Fibrous and starchy foods, in particular, can wrap themselves around the blades and cause buildups.  
  • 3. Use cleaning products   
    You can use cleaning products such as a garbage disposal brush as well as foaming cleaners to keep your garbage disposal squeaky clean. These items don’t cost much and will help prevent your garbage disposal from emitting any foul smells. You can clean your garbage disposal every two weeks or so, or even every week if you’re using your garbage disposal often.  
  • 4. Replace rubber collars   
    Whenever your rubber collars start to tear or break apart, it's time to replace them. Fortunately, replacing rubber collars is a relatively easy process, and they're also inexpensive.  
  • 5. Consider using a ‘Disposal Genie’  
    Disposal Genies are great to have for your garbage disposal as they prevent large food particles from entering your garbage disposal. Due to its unique design, only small particles of food and water can flow freely into the garbage disposal.
