How to Unclog Your Garbage Disposal Quickly and Easily
Clear a disposal clog with tools you already have at home
Your garbage disposal does some heavy-duty work in your kitchen, especially when the dirty dishes are caked with leftovers. Most of the time, clearing out clogs in your garbage disposal is a fairly easy task. If your disposal isn’t draining properly, follow these easy steps to learn how to unclog the garbage disposal.
How to Prep to Unclog the Garbage Disposal
Make sure to address a clog in your garbage disposal as soon as it happens. If you run the motor while you still have a clog, you can burn it out and cause damage.
Before unclogging the disposal, turn off your disposal and unplug it if you can. You should also turn off the power source to your disposal in your electrical panel. Garbage disposal blades are sharp, and you don’t want to risk getting hurt.
Clear the sink of any dishes, food, and excess water. Make sure you have ample lighting to see down the disposal.

Try these methods for unclogging a stubborn garbage disposal.
Manually Check and Clear the Disposal
Shine a flashlight into the disposal to see what might be clogging it. Remember to keep your hands and fingers out of the drain. If you see anything in the disposal that may be causing the clog, use pliers or tongs to remove it. Turn on the power to the disposal and check to see if the clog is gone.
Plunge the Drain to Clear the Clog
Before you plunge the drain, clamp off the dishwasher connection hose if you have one. This step prevents dirty drain water from flowing into the dishwasher.
Place a flat plunger over the sink drain and push it down and up with moderate force. Plungers use water pressure to push the water down the drain, helping to loosen any food or debris clogging the disposal.
Pour in Baking Soda and Vinegar
Sprinkle ¼ cup of baking soda into the disposal, then pour a ½ cup of distilled white vinegar. Adding this combination will help dissolve any liquid fat or grease that may be causing the clog. Once the solution has five minutes to travel through, turn on the disposal again to see if the water drains.
Use an Allen Wrench or Wooden Handle to Loosen the Impellers
At the interior base of your disposal, there's usually a hex-shaped hole in the center called a flywheel hole. The hole connects to a shaft that can manually rotate the two impellers that push the food around in your disposal.
Insert a ¼ inch Allen wrench, also called a hex wrench, or use a similar tool that came with your disposal. Turn it clockwise and then counterclockwise five times until the blades spin freely in either direction. Remove any items that were causing the clog with pliers or tongs.
If your disposal doesn’t have a hexagon-shaped hole, use the wooden handle of a broom or plunger to loosen the impellers. Push the bottom of the wooden handle against the shaft and turn it back and forth until the clog is free, then remove any junk with tongs or pliers.
Reset Your Garbage Disposal
Reset your garbage disposal by finding the reset button near the bottom of your unit, often under the sink. Press it, then turn the power back on to test it.

Contacting a Pro
If you’ve tried the above solutions and your garbage disposal is still acting up, it might be time to call in a local garbage disposal repair professional. Garbage disposals last between 10 and 15 years, so if yours is that old, consider a full replacement—replacing your garbage disposal will cost about $400.
Why Is Your Garbage Disposal Clogged?
Your garbage disposal may be clogged due to:
Thick or gritty items: Some food debris, such as eggshells, starchy vegetable peels, fruit pits, nuts, and coffee grounds, can clog your drain.
Inorganic waste: Items that belong in your trash or recycling bin can clog your garbage disposal, such as paper, tinfoil, plastic, and food packaging.
Fat, oil, and grease: Putting grease, liquid fat, and oil down your disposal drain can cause clogs because they later solidify in the pipes.
Foreign objects: Silverware, dishcloths, rubber bands, and other foreign objects can clog your disposal and harm the blades.
Not enough water: Whenever you use the disposal, you should run cold water while it grinds food waste. Otherwise, a backup can happen.
7 Tips to Prevent Garbage Disposal Clogs
Repeated clogs can wear down your disposal and, at worst, break it. Here’s how to prevent future garbage disposal clogs.
Avoid putting items such as trash, bones, fruit pits, seeds, silverware, dishcloths, vegetable peels, eggshells, fat, oil, and grease down your disposal. These items are likely to clog your drain and break your blades.
Use a sink or drain strainer to catch larger items and prevent them from going into the drain.
Feed your disposal slowly without putting too many food scraps in at once.
Run cold water every time you use the disposal and keep it on for the full duration. Hot water can cause oils and fats to spread into the pipes and then harden into a clog.
Use your disposal daily so food particles don’t sit and have the potential to clog it or corrode the parts.
Run your disposal for at least 30 seconds after you grind the food to ensure everything is processed.
Review your disposal’s instruction manual for proper use, maintenance, and cleaning.
DIY Unclog a Garbage Disposal Vs. Hiring a Pro
While unclogging a garbage disposal can be simple, you may need professional help if you have a difficult clog. Only attempt to do this DIY while keeping your hands out of the disposal—you’ll know it’s time to hire a professional plumber near you if the job requires someone to put their hands in the disposal.
If you’re planning to unclog the disposal by yourself, the supplies for a DIY job cost about $5. If your garbage disposal is clogged and requires a professional, the cost to hire a local plumber is around $45 to $200 per hour. If they discover any major issues, your cost may go up, especially if you have to repair or replace the garbage disposal.
