10 Things to Never Put Down Your Garbage Disposal (and Why)

Updated November 19, 2024

Things to Never Put Down Your Garbage Disposal

Misusing your garbage disposal can lead to failures, clogs, or even motor burnout. Let’s explore 10 things to avoid, why it matters, and how proper upkeep can keep your garbage disposal running smoothly.   

First and foremost, avoid putting these 10 common household wastes down your disposal: 

1. Butters, Oils, and Greases

These liquid fats congeal in pipes, forming stubborn clogs and potentially costly plumbing repairs. Instead, let fats cool and congeal, then wipe them up with a paper towel and toss it in the trash. 

2. Coffee Grounds

Coffee grounds clump and create sludge—ideal conditions for a clog. Better uses: compost them or scatter them in your garden.  

3. Egg Shells

Myth: They sharpen blades. Reality: They wrap around the impellers and cause motor strain. Toss them instead. 

4. Stringy Foods (Celery, Onion Skins, Corn Husks)

These fibers wrap around impellers, causing jams and overheating. Save yourself the stress—and potential service call fees. 

5. Starchy Foods (Pasta, Rice, Potatoes)

Starch expands and forms gummy blockages. A clog that cascades into water damage can be hundreds of dollars to repair, depending on severity.  

6. Bones and Shells

These are too hard—even small ones can chip or jam the disposal.

7. Fruit Pits and Large Seeds

Like bones, these can rattle and damage internal components. Pitch them, not your appliance. 

8. Nuts and Oatmeal

Grinding nuts creates sticky “nut butter” and oatmeal becomes gummy. Clogs are inevitable, repairs are not cheap. 

9. Everyday Garbage

Paper towels, wipes, and plastics don’t belong in a disposal. They can damage blades or cause serious backups. 

10. Paint

Paint can harden in pipes, cause deep clogs, and pose environmental hazards. Always dispose at a hazardous-waste center—not down the drain.

Keep Your Garbage Disposal in Top Shape 

  • Run the disposal with cold water regularly. Avoid hot water which can soften fats.
  • Break larger scraps into small pieces.
  • Clean monthly using ice and coarse salt, then rinse with cold water, or try baking soda and vinegar for deeper cleaning. 
  • Avoid chemical cleaners. They degrade internal parts. 
  • If a problem isn’t easily solvable, consider whether a repair or replacement is more cost-effective—and don’t hesitate to check if your 2-10 Home Warranty covers the issue.
