How to Unclog a Garbage Disposal
How Do Garbage Disposals Work?
Garbage disposals help minimize drain clogs by breaking up foods that are disposed of down the drain. A garbage disposal is attached to the underside of a kitchen sink drain and contains an electric motor and blades that break down food.
The blades chop up food scraps into small pieces before they reach the drain pipe where the particles are flushed down the drain with water from the tap.
It’s important to use your garbage disposal as directed by the manufacturer and to run water down the kitchen drain while using it. For more information on how to unclog your garbage disposal and how your specific garbage disposal works, consult the owner’s manual.
How Do Garbage Disposals Get Clogged?
Food particle buildup causes most garbage disposal clogs. A clogged garbage disposal can also occur when something that shouldn’t go down the garbage disposal does. Knowing how to unclog your garbage disposal immediately can prevent clogged disposals and other disposal issues later.
Keep reading to find out the general guidelines unclogging garbage disposals, and learn about garbage disposals, including what should and shouldn’t go down your garbage disposal.
What Can You Put Down a Garbage Disposal?
You can avoid a clogged garbage disposal by knowing what can and cannot go down a garbage disposal. Typically, garbage disposals can handle food scraps, like pieces of fruit, cooked meat and vegetable scraps.
However, there are certain biodegradable items that shouldn’t be put down a garbage disposal. These include fibrous scraps like celery, onion skin and cornhusks. While these are all organic matter, pieces can get tangled in the blades.
You should also avoid putting oils and fats like bacon grease, butter and cooking oils down the drain as they can coagulate and cause blockages that lead to clogged disposals. The same goes for putting pasta, rice and some starchy vegetables down the garbage disposal. These foods can expand when wet and create a paste that causes garbage disposal clogs.
Keep items like banana peels and hard items like fruit pits or bones out of your garbage disposal. And, always avoid putting nonfood items like paper scraps or cigarettes in the garbage disposal.
Coffee grounds can also cause trouble in a garbage disposal. Putting coffee grounds down your disposal might seem like a good way to make your kitchen smell good. However, grounds will quickly build up at the bottom of your drain and create a thick sludge that can lead to a clogged disposal.
If you’d like to deodorize your drain, it’s best to put small pieces of citrus peel down your garbage disposal. There are also garbage disposal drain cleaning products designed to deodorize drains, like Disposal & Drain Cleaner. Just drop one quick-dissolving pack into your garbage disposal for a clear drain and fresh citrus scent.
How Do You Unclog a Garbage Disposal?
So, how do you fix a clogged garbage disposal? If your kitchen sink isn’t draining and seems jammed, you can plunge it using a kitchen plunger to dislodge the debris that’s clogging your disposal. (Note: A kitchen plunger is different than a toilet plunger.)
To plunge the drain, tighten a clamp over the rubber part of the drain line to your dishwasher, which can be found under your sink.
Place the plunger over the clogged sink drain and fill it with water (approx. 3–4 inches). Hold a wet rag over the adjacent drain and plunge vigorously for several minutes.

Also, when you’re working to unclog your garbage disposal, never put your hand down your kitchen sink drain in an effort to reach the clog or something else that may be stuck. If something like a piece of silverware falls in by accident, turn the disposal off and use tongs to retrieve the item.
