Garbage Disposal Do's and Don'ts Every Homeowner Should Know

Garbage disposals make kitchen cleanup easier—but they aren't designed to handle everything.

Knowing what should (and shouldn't) go into your disposal can help prevent costly plumbing repairs.

Foods That Are Safe

Most soft food scraps are fine in moderation, including:

• Small fruit scraps

• Cooked vegetables

• Soft leftovers

Always run cold water before, during, and after using your disposal.

Foods to Avoid

These items commonly cause drain clogs:

• Grease, fats, and cooking oil

• Coffee grounds

• Eggshells

• Pasta

• Rice

• Potato peels

• Bones

• Corn husks

• Celery

• Onion skins

These materials either expand, harden, or wrap around the disposal blades.

Don't Forget About Non-Food Items

Your garbage disposal should never be used for:

• Paper towels

• Plastic

• Metal

• Glass

• Produce stickers

• Twist ties

Even small objects can damage the unit or clog your plumbing.

Signs Your Garbage Disposal Needs Service

Call a plumber if your disposal:

• Frequently jams

• Makes unusual grinding noises

• Leaks underneath the sink

• Won't turn on

• Leaves standing water in the sink

• Produces persistent foul odors

Protect Your Plumbing

A garbage disposal is a convenience—not a trash can. Using it properly can extend its lifespan while helping prevent clogged kitchen drains.
