What Can I Not Put in the Garbage Disposal?

Garbage disposals are a wonderful invention that makes cleaning up after meals much easier. However, not everything should go down the disposal. Putting the wrong things in can damage the appliance and cause clogs in your pipes. In this blog, we'll cover some of the things you should avoid putting in your garbage disposal to keep it running smoothly.

Grease or Oil

It's tempting to use your garbage disposal as a way to dispose of cooking grease or oil, but this is a big no-no. The grease will solidify as it cools, leading to blockages and sewer backups. Instead, pour the grease into a container and throw it away in the trash once it's cooled down.


While eggshells are biodegradable, putting them down the garbage disposal is not the way to dispose of them. The membrane lining inside the eggshell can wrap around the disposal blades and damage the motor. It's best to throw them away in the trash.

Fibrous Foods

Stringy, fibrous foods like celery, asparagus, and banana peels can cause clogs in your garbage disposal. They can wrap around the blades and cause the motor to burn out over time. If you need to dispose of these kinds of foods, throw them away in the trash or compost them.

Coffee Grounds

Coffee grounds may seem harmless, but they can create blockages in your drain. They can clump together in the pipes and cause a clog. Instead, throw them away in the trash or use them in your garden as a soil conditioner.

Garbage disposals are an incredibly handy appliance to have in your home, but they require some care and attention to keep them running smoothly. Remember to avoid putting grease, eggshells, fibrous foods, coffee grounds, or non-food items down the disposal. Following these tips can help prevent clogs and damage to the blades and motor, saving you time and money in the long run.
