Garbage Disposal Do's and Don'ts for Tucson Homeowners

Garbage disposals are one of the most misunderstood appliances in the kitchen. They are not designed to process food waste broadly — they are designed to handle incidental scraps that make it into the sink while rinsing dishes. When they are treated as a catchall food processor, they fail faster, clog drains, and create odors. Here is the honest guide to running yours properly.

What Belongs in a Garbage Disposal

• →Small soft food scraps: cooked vegetables, fruits, small bits of meat
• →Ice cubes — help clean the grinding chamber and sharpen blades
• →Small citrus peels (lemon, lime) — neutralize odors naturally
• →Dish soap and cold water — run during and after every use
• →Cooked pasta and rice in very small amounts (never large portions)

What Never Goes in a Garbage Disposal

• →Grease, oil, or fat — even liquid form. It solidifies in the drain line and builds up over time into a blockage that no amount of hot water fixes.
• →Fibrous vegetables: celery, artichokes, asparagus, corn husks. The fibers wrap around the motor shaft and jam it.
• →Starchy foods in volume: large portions of pasta, rice, potato peels. They swell with water and turn into paste that clogs the drain.
• →Bones and pits — even "soft" bones can crack the grinding plate or jam the motor.
• →Coffee grounds — they are too fine, accumulate in the trap, and contribute to clogs.
• →Eggshells — a persistent myth says they sharpen blades. They do not. The membrane wraps around the shaft.
• →Non-food items of any kind — no labels, twist ties, or broken glass.

Proper Use Every Time

Always run cold water before, during, and for 15 seconds after running the disposal. Cold water keeps fats in solid form so they are ground and flushed rather than coating the pipe walls. Never run it dry — the water flushes the grinding chamber and carries waste down the drain line.

When It Stops Working

Before calling a plumber, check two things: the reset button (a small red or black button on the underside of the unit — press it firmly until you feel a click) and the Allen key port (also on the underside — use a 1/4-inch Allen key to manually turn the motor if it is jammed). If it hums but does not spin, it is jammed. If it is completely silent, the reset or the switch is the issue.
