Have you ever found yourself in a situation where your garbage disposal is suddenly not working as efficiently as it used to? You might have a common culprit: eggshells clogging your disposal. Don't worry, you're not alone, and we're here to help you understand why this happens and how to prevent it.
Why Eggshells Clog Garbage Disposals
Eggshells might seem harmless, but they can cause significant issues for your garbage disposal. The problem lies in the membrane that lines the inside of the eggshell. This membrane is tough and rubbery, and it can wrap around the disposal's impeller blades, causing them to jam or stop working altogether. Additionally, eggshells are sharp, and over time, these sharp edges can damage the blades, reducing their effectiveness.
Signs of Eggshell Clogging
Before we dive into how to unclog your garbage disposal, let's look at some signs that eggshells might be the cause of your disposal's troubles:

- Gurgling noises when you turn on the disposal
- The disposal doesn't spin or spins slowly
- Water drains slowly from the sink
- The disposal makes a humming noise but doesn't grind
How to Unclog Your Garbage Disposal
If you suspect eggshells are clogging your garbage disposal, here are some steps you can take to unclog it:
Manual Method
If your disposal is jammed, you can try to manually turn the impeller blades. First, make sure the disposal is unplugged. Then, locate the Allen wrench that came with your disposal (it's usually stored under the sink) and insert it into the hole at the bottom of the disposal. Turn the wrench back and forth to try and free the blades.
Plumbing Snake
If the manual method doesn't work, you might need to use a plumbing snake. Insert the snake into the disposal and feed it down the drain. Once you feel resistance, turn the snake to try and dislodge the clog.

Baking Soda and Vinegar
For a more natural approach, you can try using baking soda and vinegar. Pour a cup of baking soda into the disposal, followed by a cup of vinegar. The mixture will fizz and help to break up the clog. Let it sit for about 30 minutes, then run hot water down the drain to flush out the clog.
Preventing Eggshell Clogging
Now that you know how to unclog your garbage disposal, let's look at some ways to prevent eggshells from clogging it in the first place:
- Don't put eggshells down the disposal. Instead, compost them or throw them in the trash.
- Run cold water while using the disposal. This helps to keep food particles moving and prevents them from clumping together.
- Regularly clean your disposal with citrus peels. The acid in the peels helps to break down grease and food particles.
- Don't put hard or stringy foods down the disposal. These foods can wrap around the blades and cause jams.
Remember, prevention is always better than cure. By taking these steps, you can keep your garbage disposal running smoothly and avoid the hassle of unclogging it.
When to Call a Professional
While these tips can help you unclog your garbage disposal, there are times when it's best to call a professional. If your disposal is making strange noises, leaking, or not turning on at all, it's a good idea to contact a plumber. They have the tools and expertise to diagnose and fix the problem safely and effectively.
In conclusion, eggshells can cause significant issues for your garbage disposal, but with the right knowledge and tools, you can keep your disposal running smoothly. By understanding why eggshells clog disposals and taking steps to prevent it, you can save yourself time, money, and frustration in the long run.
