A garbage disposal feels like it can handle anything — until it can't. A few habits make the difference between a disposal that lasts over a decade and one you're replacing every few years.
It's a disposal, not a trash can
The biggest misconception about garbage disposals is that they're built to handle anything that fits down the drain. In reality, they're designed for small amounts of soft food scraps, not fibrous, starchy, or hard materials. Treating it more selectively goes a long way.
Do
- Run cold water before, during, and after using the disposal
- Cut larger food scraps into smaller pieces before putting them in
- Run it regularly, even with just water, to keep parts from seizing up
- Use a bit of dish soap and water occasionally to help clear odors and residue
- Reset the unit (usually a button underneath) if it hums but won't spin
Don't
- Don't put fibrous foods like celery, corn husks, or onion skins down it
- Don't dispose of coffee grounds, eggshells, or large amounts of rice or pasta
- Don't pour grease or oil down with it, even while it's running
- Don't put hard items like bones, fruit pits, or glass down the disposal
- Don't run hot water while grinding — it can soften grease and let it coat pipes
Quick tip: If your disposal hums but doesn't spin, don't force it repeatedly — that's often a jam that needs to be cleared safely rather than powered through.
