Most homes in Edmond and Oklahoma City have garbage disposals, but there’s a surprising amount of controversy about what you can and can’t put down your garbage disposal.
When we had a plumbing department, I would constantly hear horror stories from our plumbing technicians about what they encountered in the field!
Food that shouldn’t go down your garbage disposal can gunk up the disposal and dull the blades, making it less effective. And of course, over time that can cause them to break! I recall breaking one or two garbage disposals as a child, which my parents were not happy about…
Based on what our plumbers shared and some online research, I’ve compiled a list of what’s generally okay and what’s not okay to put down your garbage disposal. I was surprised to find so much controversy online over what you can and can’t put in the disposal, so I would just say to err on the side of caution if you’re concerned about damaging your disposal.
- Small citrus peels (admittedly one of the more controversial items)
- Soft foods
- Small amounts of cooked vegetables or meat (like leftovers)
- Grease, fats, and oils (These will coat the blades of your disposal, making it work harder.)
- Eggshells (Ground-up eggshells mixed with grease can really gunk up your drain lines!)
- Vegetable peels
- Actual garbage (Paper, rubber bands, plastic, etc.)
- Rice and pasta (They expand when exposed to water, even after being cooked. Yikes!)
Or, think of it this way: If you could feed it to an infant, then it will probably be okay to go down your drain.
You should also run your garbage disposal with cold water when you’re grinding up food particles—that way the natural oils and fats in some foods won’t get stuck in your disposal blades. After running the disposal, though, it’s perfectly okay to run hot water down the drain.
I know we like to think of our garbage disposal as something that simply gets rid of the things we don’t want to scrape into the trash can (and to an extent that’s true) but it might help to also think about it like an appliance, too. Being careful about what you put down the disposal can help you maintain that appliance over the years.
