Kitchen Sink Plumbing 101: Cleaning Your Garbage Disposal

If you have a garbage disposal as part of your kitchen sink, it is important to clean it to prevent foul odors from stinking up the kitchen. The foul odors come from grease, food particles, and other such things that get stuck to the inside of the garbage disposal and the kitchen sink plumbing.

There are several effective methods for cleaning the disposal to keep odors away and your disposal working great. To clean your disposal, you will want to gather the following cleaning supplies:

  • Grease-Cutting Dish Soap
  • Sponge
  • Vinegar
  • Baking Soda
  • Ice
  • Kosher/Rock Salt
  • Lemons or Limes

Once you have your cleaning supplies ready, the first and most important step is to make sure your disposal is off.

WARNING: Before cleaning your disposal, make sure to unplug it from the power outlet or shut off the breaker in your breaker box. Verify the disposal does not have power by turning it on. If you shut it off correctly, it will not turn on.

Step 1: Wash the inside of the disposal.

Wet the sponge in warm water and apply a liberal amount of grease-cutting dish soap. Scrub the inside of the disposal chamber. If you have a dual-sided sink, fill the non-disposal side with warm water to rinse the gunk out of the sponge. Reapply more dish soap if needed and repeat. Allow the dish soap to penetrate and cut through the grease for 5 to 10 minutes. Rinse out the disposal with warm water.

Step 2: De-gunk the hard-to-reach areas of the disposal.

Pour one-half to three-quarters of a cup of baking soda into the disposal. Slowly add an equal amount of vinegar into the disposal. You will hear the two interact and start foaming. Place the sink drain cover over the drain opening.

Allow the fizzing action to work for 15 to 20 minutes. Rinse the disposal out with cold water by allowing it to run down the drain for about 2 to 3 minutes.

Step 3: Remove difficult buildup from the disposal chamber.

Fill the disposal full of ice cubes. Pour in about one cup of kosher or rock salt. Plug the disposal back into the outlet or turn the breaker switch back on. Turn on the cold water so it trickles down the drain and turn on the disposal. The ice and salt “scrub” the inside of the chamber.

Step 4: Freshen up the disposal.

Take your lemons or limes and cut them into quarters. Be sure to remove any seeds and discard them. Drop the citrus pieces down the disposal and turn it on while running cold water down the drain. The oils in the citrus freshen up the disposal and drain and make it pleasant-smelling.

How frequently should I clean my garbage disposal?

It depends on how much you use it. If you use it every day, then you want to clean it every 1 to 2 weeks. If you use it a few times each week, then once a month is sufficient. Part of keeping your disposal clean is also paying attention to what you put in it.

You should never put any of these items into the disposal:

What Things Shouldn’t Go in a Garbage Disposal and Why?

Garbage disposals are wonderful appliances many homeowners have, as they help break down many different types of food wastes. When used correctly, they can prevent a clogged kitchen sink, compared to putting food waste down a sink drain without a disposal.

However, you need to remember, garbage disposals do not work with all types of food waste. This is a common misconception many homeowners take for granted. Unfortunately, they learn the hard way that their disposal was not designed for certain things when it stops working, a clog develops, or other problems appear.

Not sure if you are using your garbage disposal correctly? Then check out our plumbers’ list of things you should never put into a garbage disposal:

  • Rice and Pasta: Both rice and pasta will continue to absorb water, even after it is cooked to your preference. If you dump it down the disposal, the small bits that go down the drain will get bigger and can lead to clogs. Plus, pasta and rice can get stuck in the disposal’s drain trap.

  • Potatoes/Potato Peelings: Potatoes are starchy and can create a big mess in your disposal. Cold water and potatoes make a paste that is gummy and can create sink clogs. Potato peelings are equally starchy and also hard to grind up. Not to mention, any residues, if you do avoid problems, still smell very bad.
  • Hot Grease: Hot grease and cold water do not mix. The cold water causes the grease to cool and stick to the insides of the components on the disposal, as well as the drain pipes.
  • Bones of Any Size or Shape: Bones do not play well with your disposal. The blades might be able to crack and snap some smaller ones. Even if they do make it through the disposal, the bits and pieces can create a clog.
  • Coffee Grounds: The grounds may seem small and like they would go easily down the disposal. Yet this is not the case, and used coffee grounds can turn your sink into a big mess. The friction caused while running the disposal turns them into sludge.
  • Fibrous Vegetables: Vegetables that have fibrous strings in them, such as celery and asparagus, can cause problems for your disposal. The strings wrap around moving parts and components and can cause the disposal to overheat and stop working.
  • Corn Cobs/Silk/Husks: These things are rough on your disposal and only create more problems in the long run. The cobs will not break down easily and could create a clog. The silk and husks are stringy and will wrap around moving parts.

By avoiding putting these items into your disposal, not only will it last longer, but you also can avoid kitchen sink plumbing problems.
