What Should You Never Put in a Garbage Disposal?

Posted October 16, 2017

While garbage disposals are incredibly convenient for managing kitchen waste, not everything belongs in them. Misusing your disposal can lead to clogs, damage, and costly repairs. Knowing what not to put in your garbage disposal is key to keeping it running smoothly and prolonging its lifespan. Let’s dive into what you should avoid and why it matters.

Why Does It Matter?

Garbage disposals are designed to handle small amounts of food waste, but they aren’t indestructible. Misusing your disposal can lead to a host of problems, including clogged pipes, damaged blades, and even motor failure. Understanding the limitations of your garbage disposal can save you time, money, and the hassle of calling a plumber during the busiest times of the year.

Items You Should Never Put in Your Garbage Disposal

While many items are safe for your garbage disposal, several common household materials can cause serious issues. Here are some items to avoid:

1. Grease and Fat

It might seem logical to pour grease or fat down the disposal since it’s a liquid, but this is one of the biggest mistakes homeowners make. Grease solidifies as it cools, creating a sticky residue that can build up over time and cause significant clogs. Instead, collect grease in a disposable container and throw it in the trash once it solidifies.

2. Fibrous Vegetables and Fruits

Vegetables like celery, asparagus, and corn husks, as well as fruit peels like banana skins, are problematic because their fibrous texture can wrap around the disposal blades. This can cause the motor to overheat and even damage the blades. Compost these materials if possible, or throw them in the trash.

3. Starchy and Grainy Foods

Foods like pasta, rice, and coffee grounds may seem harmless, but they can expand when exposed to water, leading to clogs in your pipes. Grainy materials like coffee grounds can also form sludge that clogs the drain. Dispose of these items in your compost or trash instead.

4. Animal Bones

While garbage disposals are robust, they aren’t built to handle hard materials like bones. Bones can damage the blades or get stuck in the disposal, rendering it inoperable. Instead, use bones to make a broth or stock, and discard them in the trash once you’re done.

5. Eggshells

There’s a common myth that eggshells are good for sharpening disposal blades, but this isn’t true. The membrane inside the shell can wrap around the blades, while the shell fragments can accumulate and contribute to clogs.

6. Non-Food Items

It should go without saying, but non-food items like plastic, paper, and metal have no place in your garbage disposal. These materials can severely damage the blades and motor, requiring expensive repairs or replacement.

How to Maintain Your Garbage Disposal

To keep your garbage disposal running smoothly, follow these maintenance tips:

  • Run Cold Water: Always run cold water while using the disposal to help flush food particles down the drain.
  • Clean Regularly: Use a mixture of baking soda and vinegar or grind up ice cubes and citrus peels to clean and deodorize your disposal.
  • Avoid Overloading: Feed food waste into the disposal gradually to avoid overwhelming the system.
  • Inspect Periodically: Check the disposal and surrounding pipes for leaks or signs of wear and tear.

What to Do if Your Disposal Is Clogged or Damaged

If your garbage disposal is clogged or malfunctioning, avoid using chemical drain cleaners, as they can damage the appliance and your plumbing. Instead, try these steps:

  1. Turn off the disposal and unplug it.
  2. Use a flashlight to inspect the interior for visible obstructions.
  3. Use tongs or pliers to remove any debris—never use your hands!
  4. Reset the disposal using the button on the bottom of the unit.

If these steps don’t resolve the issue, it’s time to call a professional plumber to inspect and repair the system.
