Garbage disposals and disposals are plagued by numerous issues that necessitate repair. When the impeller blades inside the appliance become tangled with foreign things, they can become stuck. It is possible for the drain fittings to come free and cause water to spill under the sink. As an alternative, clogged drains can create back-up of water into the sink basin where the garbage disposal is placed, resulting in a flooded kitchen floor.

How to Clean a Garbage Disposal in 6 Steps - This Old House

Double basin sinks with only the disposer basin backing up are likely to have a clogged disposal’s drain fitting.


There are a few simple steps you can do to maintain your garbage disposal running smoothly. The maintenance of a garbage disposal is easy if you do the following five things:

  1. Cold water is better for your garbage disposal drain than hot water, which may seem paradoxical since hot water is excellent for breaking down food. However, the breakdown of fatty compounds in hot water may lead them to coagulate and form clogs lower down. You’ll be able to transfer fatty objects down the garbage disposal drain more readily if you use cold water, which will make them more solid.
  2. It may seem foolish to be urged to use your waste disposal on a frequent basis, but we may believe that doing so only when absolutely necessary will extend its lifespan. The exact opposite, however, is true. Regular use of the garbage disposal might lead to premature disposal replacement due to corrosion and rust. Using it also keeps the disposal’s parts moving, preventing trash from building up and clogging the systems.
  3. Keep recycling and trash bins out of the way: With a garbage disposal, you don’t get rid of your trash can or recycling bin. Even while a garbage disposal is a convenient addition to any kitchen, it isn’t a replacement for a typical trash can or recycling bin, since many items should not be thrown down the disposal. It is still advisable to throw away non-biodegradable food items in the garbage rather than recycle them.
  4. Keep it clean: A clean garbage disposal not only prevents obstruction and clogs, but it also keeps any unwanted aromas at bay. Regular cleaning with diluted dish detergent and water can help avoid trash from building up inside the mechanics, as will emptying it as often as possible.
  5. Make sure to cut up large meals before putting them in the garbage disposal to avoid clogging or blocking it. In order to get the most out of your garbage disposal, it’s best to break down large chunks of food into smaller pieces before placing them into the disposal.

NEVER Put These Items down the Garbage Disposal:

  1. A variety of materials, including glass, metal, plastic, and paper (including cigarette butts, fruit stickers, string ties, etc.).
  2. Fat, oil, or lard (including meat fat and cheese). Either repurpose or discard your grease by putting it in a metal or glass container.
  3. Fibrous or starchy vegetables (such as celery stalks, corn cobs, artichoke hearts, onion rinds, and potato hulls, for example) These hard vegetables should be avoided at all costs, even in tiny amounts.
  4. There are two options: pasta or rice (foods that expand when water is added).
  5. Foods that can break down into smaller pieces (such as small fish or chicken bones) should be avoided.
  6. Anything in huge quantities (large amounts of anything will cause a garbage disposal clog).

Walking on Eggshells:

Some plumbers advise against disposing of egg shells or coffee grounds in the garbage disposal, while others believe that doing so helps sharpen and clean the disposal, and that doing so helps reduce unpleasant aromas in the garbage disposal itself.

If you have a septic tank, however, you should also be aware that eggshell membranes and coffee grinds might block your pipes and drains as well. A little amount of eggshells and coffee grounds can be thrown down the garbage disposal, but it’s recommended to avoid doing so.

Go to your garbage disposal’s user manual for detailed directions on what to put in and out of your disposal.

Garbage Disposal Don’ts:

  1. When grinding is complete, do not switch off the water or garbage disposal. Wait 15 to 20 seconds after shutting off the disposal before turning the water off.
  2. Bleach or drain cleansers, for example, should never be used.
  3. Garbage disposals are frequently used to dispose of things like coffee grounds and egg shells, but doing so can lead to clogs and other issues. Avoid this at all costs.
  4. Keep in mind that your garbage disposal is not a trashcan, and that it should only be used for food scraps.
  5. Never put anything down the disposal, not even your hands! First, turn off the waste disposal’s power switch, which is found on the bottom of the unit. Disposal can be turned off at the main electrical panel if you can’t find a switch.

Garbage Disposal Do’s:

  1. With a forceful stream of cold water, grind food waste (it helps solidify any grease or oil).
  2. The following step is to flush the garbage disposal with hot water for 10-15 seconds after the disposal has been turned off.
  3. Smaller bits can be fed in one at a time instead of all together.
  4. To prevent rust and corrosion, run your waste disposal frequently.
  5. Make sure there aren’t any little objects around your waste disposal by clearing the area around it.
  6. Disposal units need to be shut off at the source before anything can be removed, so make sure you do this by either flipping the switch underneath your disposal unit or turning it off at the breaker panel.

Methods to Empty your Garbage Disposal

First, we need to remove the rubber fitting that prevents spoons and other items from falling into the waste disposal by loosening the screws.

To remove it, simply push it out with your fingertips. The end. Make sure the garbage disposal is turned off before removing the fitting. Your fingers could be in danger if you do this.

Let’s move on to the specifics.

  1. Take a flashlight and shine it into the garbage disposal drain to see if there are any objects that have become lodged inside. Use pliers or tongs, being cautious not to damage the grinder while removing whatever it is.
  2. You can use 2 cups of ice, 1 cup of rock salt, or a combination thereof to unclog your drain. Turn on the garbage disposal, and then run some cold water through it. During the process of grinding, the ice cubes and salt will clean the grinding chamber and remove any material that has been stuck to them.

You may also use ice cubes and salts to keep your garbage disposal in top shape and remove unpleasant aromas.

Methods to Remove Bad Odor

Run the garbage disposal for a few minutes with a lemon, orange, or other citrus fruit down the drain to freshen it up and make your kitchen smell wonderful. There’s nothing to worry about because the citrus acid’s got this covered. The blades will be cleaned and the odor will be eliminated.

If you don’t mind a little splashing, you may always replace the rubber fitting back in place when it’s removed.)

  • Sprinkle half a cup of baking soda into the drain hole and then pour a cup of vinegar on top of it. Allow it to settle for 10 minutes before slicing into it. Rinse the garbage disposal with hot or boiling water after it has been running for a few minutes.

Pro Tip:

Disposal grease will solidify and be more difficult to remove if you use drain cleaner bleach, which contains ammonia. Also, there’s a good chance they’ll spill out and get all over your clothes or your eyes, which would be a total disaster. Because of this, it is not suggested that you utilize it.
