Your kitchen’s garbage disposal is one of those small appliances that makes life easier, managing food scraps and keeping your kitchen clean. But while it can handle a lot, it’s not indestructible.
What You Can Put in the Garbage Disposal
1. Soft Fruits and Vegetables
Peels, small pieces of fruit, and soft vegetables like zucchini, tomatoes, and apples are perfectly fine. These break down easily and wash away without damaging the blades or causing buildup.
2. Cooked Meat Scraps (in moderation)
Tiny bits of cooked meat (like what’s left on a dinner plate) can safely go down the disposal. Just avoid sending large chunks or fatty cuts that could clog the drain.
3. Small Amounts of Rice or Pasta
While it’s best to throw most grains in the trash, a small amount that slips into the sink won’t hurt. Run cold water to help flush it through, as these foods tend to expand when wet.
4. Citrus Peels
Lemon, lime, and orange peels not only grind well but also help freshen your disposal. The natural oils act as a mild cleanser, reducing odors.
5. Ice Cubes
Tossing in a few ice cubes every now and then helps sharpen the disposal blades and remove debris buildup. Some people even mix in a few rock salt granules for extra scrubbing power.
6. Dish Soap and Cold Water
After running your disposal, let cold water flow for 15–30 seconds to rinse away residue. Cold water keeps fats solid so they can move through the pipes more easily, preventing buildup in your plumbing.
What You Can’t Put in the Garbage Disposal
While the disposal is tough, it’s not designed to handle everything. Putting the wrong items down can dull blades, clog drains, or burn out the motor—leading to inconvenient (and sometimes expensive) garbage disposal repair.
1. Grease, Fat, and Oil
It might go down as a liquid, but it solidifies once it cools, coating your pipes and causing blockages. Always pour cooking grease into a jar or container to cool and toss it in the trash instead.
2. Fibrous Vegetables
Celery, corn husks, asparagus, and onion skins can wrap around the blades and jam the motor. These stringy fibers act like rope, tangling in the disposal and stopping it from turning.
3. Coffee Grounds
They seem harmless, but coffee grounds can clump together and create a dense, sludgy buildup in your pipes. Over time, that can cause slow draining or full blockages.
4. Eggshells
While some people think eggshells sharpen the blades, the truth is the thin membranes inside them can stick to the sides of the unit or wrap around moving parts.
5. Bones and Fruit Pits
Chicken bones, rib bones, and fruit pits (like those from peaches or avocados) are too hard for the blades and can damage the grinding chamber. Even small fragments can jam the motor.
6. Potato Peels and Starches
Potatoes, pasta, and rice create a sticky, glue-like paste when ground up, which can cling to the inside of your disposal and pipes.
7. Non-Food Items
It might sound obvious, but items like paper towels, plastic, metal, or glass should never go down your disposal. Even small utensils can slip in unnoticed—always check before turning it on.
How to Keep Your Garbage Disposal Running Smoothly
Run cold water before, during, and after each use to keep everything moving smoothly.
Feed items slowly, rather than dumping a full plate of scraps in at once.
Clean it regularly by grinding a few ice cubes and citrus peels, followed by a rinse with baking soda and vinegar.
Listen for unusual noises like grinding or humming—these could indicate something is jammed or worn out.
Even with proper care, disposals wear out over time. A little care and attention go a long way toward keeping your kitchen sink in top shape.
