Garbage Disposal Care: How to Make Yours Last Longer

April 27, 2026 — Burleson, TX Your garbage disposal works hard every day, grinding up food scraps so they wash safely down the drain. Like any hardworking appliance, it needs a little care to keep running smoothly for years. A few simple habits can mean the difference between a disposal that lasts a decade and one that quits after a couple of summers.

What Belongs in a Disposal — and What Doesn’t

The fastest way to shorten the life of a disposal is to feed it the wrong things. Stick to soft food scraps, and feed them in slowly. Safe to grind:

• Soft fruits and vegetables
• Small bits of cooked meat
• Citrus peels in moderation — they help freshen the unit
• Ice cubes — great for knocking buildup off the impellers

Keep these out:

• Grease, fat, and cooking oil — they cool, harden, and clog the drain
• Coffee grounds and eggshells — they build up a fine grit and sludge
• Fibrous foods like celery, corn husks, onion skins, and artichoke leaves
• Starchy foods like potato peels, rice, and pasta — they swell and gum up the chamber
• Bones, fruit pits, and seafood shells
• Anything non-food — twist ties, rubber bands, sponges, glass

The Right Way to Run the Unit

• Always run cold water before, during, and for at least 15 seconds after grinding. Cold water keeps fats solid so they get pulverized and flushed away.
• Feed scraps in a little at a time. Overloading the chamber strains the motor.
• Let it run a few seconds after the grinding noise stops, so the chamber is empty before you shut it off.
• Use the disposal regularly. Sitting unused lets parts rust and food residue harden inside.

A Simple Monthly Cleaning Routine

A clean disposal smells better and lasts longer. Once a month:

• Drop in a handful of ice cubes and a tablespoon of rock salt, then run with cold water. The ice and salt scrub the grinding components.
• Toss in a few citrus peels and grind with cold water for a fresh, natural scent.
• For deeper cleaning, pour in a half cup of baking soda, follow with a cup of white vinegar, let it foam for a few minutes, then flush with cold water for 30 seconds.

Skip the chemical drain cleaners. They corrode the seals, splash guard, and metal parts inside the unit.

Warning Signs to Watch For

Even with great care, disposals eventually wear out. Call a plumber when you notice:

• A persistent humming sound with no grinding — usually something is jammed
• Water leaking from underneath the unit
• Slow drainage even when nothing is clogged upstream
• Smells that come back right after cleaning
• Loud rattling or metallic grinding noises
• The reset button that won’t stay reset
