What Not to Put Down Your Garbage Disposal

Ah, the garbage disposal. Whether you’re a new homeowner or have been living in your house for years, it is important to understand what should and should not go down your garbage disposal. While some things may seem harmless enough, they can cause a major headache (and an even bigger plumbing bill) if you’re not careful. Let’s take a look at the basics of garbage disposal safety and what not to put down there. 

Grease & Oil

Grease and oil can seem like an easy way to quickly get rid of food leftovers. However, these liquids harden when cooled and accumulate in your pipes over time. If too much builds up, it could lead to clogs or even pipe damage. In addition, grease and oil can also cause motor burnout if poured directly into the disposal unit itself.

Fibrous Foods & Starchy Foods

Fibrous foods like celery strings as well as starchy foods like potato peels, pasta or rice tend to clump together when they hit water which can easily create clogs in your pipes that are nearly impossible to remove without professional help. To avoid this problem altogether, simply throw fibrous and starchy foods somewhere other than the kitchen sink!

Eggshells & Coffee Grounds

Eggshells and coffee grounds are two more items that should not go down the drain. Both of them have rough surfaces which means that they can easily scratch the sides of your garbage disposal unit or catch onto something else causing a blockage in the system. Additionally, coffee grounds have a tendency to stick together creating unwanted buildup inside the unit over time.

Fruit Pits & Seeds

Fruit pits are another item that should never be placed into your garbage disposal due to their hard outer shells that could potentially damage blades over time if used too often. Also keep in mind that seeds from fruits like avocados contain fatty oils which could lead to clogs if they end up stuck in your pipes so it’s best just to avoid putting any fruit pits or seeds down altogether!  


Overall, it’s important to be mindful of what you are putting down your garbage disposal so that you don’t end up with any costly repairs or replacements later on down the line. While some kitchen scraps may seem small enough for your garbage disposal right away, certain items like grease and oil, fibrous foods and starchy foods, eggshells and coffee grounds should all be thrown away elsewhere instead! By following these simple tips you can keep your garbage disposal functioning smoothly at all times!
