Ice, Lemon Peels or Vinegar: What Actually Cleans a Garburator?

Ice, lemon peels, vinegar or a tablet: what actually cleans a garburator

Each one does a different job. Ice scrubs, citrus covers smells, vinegar and baking soda fizz, and a cleaner tablet cleans the residue itself. Maker quotes were checked October 20, 2026.

What InSinkErator, Moen and Waste King actually say

Word for word, from the three garburator makers we checked:

Ice cubes in a garbage disposal: a scrub, not a sharpener

• It does scour. Hard bits knock loose food stuck where they're ground, at the turntable and grind ring.
• There's nothing to sharpen. InSinkErator's FAQ says its units "don't have blades or knives": lugs throw food against a stationary grind ring.
• How: cold water on at a medium stream, garburator on, a handful of ice. GE adds a tablespoon of rock salt.

Lemon peels in a garbage disposal: good for the smell, not the residue

Citrus covers drain smells; it doesn't remove what's causing them. InSinkErator's own words are "freshen up," and it says a smell usually means food buildup. Feed peels in gradually with the water and unit running: its manual says not to fill the disposer with a lot of peels at once. Leftover peels from juicing are free; a whole lemon cost 97¢ at Walmart.ca on October 20, 2026.

Vinegar and baking soda in a garbage disposal: mostly fizz

Vinegar is an acid and baking soda is a base, so they neutralize each other. The fizz is carbon dioxide from that reaction, not scrubbing. What's left is mostly water and sodium acetate, a salt.

• The popular recipe comes from GE Appliances: 1/2 cup of baking soda, then 1 cup of white vinegar, 10 to 15 minutes, then a hot-water flush. InSinkErator, Moen and Waste King don't mention vinegar at all.
• InSinkErator's own version is baking soda only: half a sink of warm water with 1/4 cup, then run the unit as you pull the stopper to wash loose particles away.
• Never with bleach. Health Canada warns that bleach reacts with any cleaning product containing an acid, including vinegar, and gives off toxic gases.

A cleaner tablet: what InSinkErator's manual describes

A tablet is the one option made for the residue itself. BLITZ Disposal Cleaner & Deodorizer foams through the grinding chamber, where food residue and grease build up, and leaves a light citrus scent. Its product page lists citric acid, sodium carbonate and foaming surfactants: the surfactants lift grease, which an acid alone doesn't.

• How: a thin stream of hot water, one tablet, garburator on while it foams, then a few seconds of rinse. Two tablets for 3/4 and 1 HP motors; one or two for 1/2 HP.
• Hot water is fine here. InSinkErator says no hot water while grinding food, but "it is OK to drain hot water into the disposer between grinding periods," which is when the tablet goes in.

Finish with the rubber splash guard flaps, where Waste King says most odours start: power off and scrub their underside with baking soda and warm water. Full steps, with the safety rules: how to clean a garburator safely.

Get 24 tablets, about a year of cleans

Garburator cleaning myths, and what not to do

• "Hot water flushes the grease." InSinkErator: "Don't use hot water when grinding food waste." GE explains why: cold water firms up grease so it gets chopped and flushed.
• No chemical drain cleaner. InSinkErator and Waste King both rule out caustic drain cleaners, and Moen says lye or chemical drain cleaners "cause serious corrosion of metal parts."
• Never mix products. Not vinegar or a citric acid tablet with bleach, and not a tablet in a sink that still holds a drain cleaner.

Cost per clean, at regular prices (October 20, 2026)

Regular online prices on Walmart.ca, not sales; amounts per clean are our estimates. Prices move and vary by store.

Over a year, BLITZ costs less than the weekly fizz. At one tablet twice a month, a box is $24.95 a year. Vinegar and baking soda every week come to about $26 a year (52 × 50¢), for a fizz that no garburator maker we checked recommends.

A garburator cleaning routine that works

1. Every use: cold water, and grind until you hear only the motor and water.
2. Now and then: ice and a few citrus peels, for the smell.
3. Every week or two: power off, scrub under the splash guard.
4. Twice a month: one BLITZ tablet with a thin stream of hot water.

Frequently asked questions

Do ice cubes sharpen garbage disposal blades?

No. Garburators have no blades: lugs push food against a fixed grind ring. Ice only scours.

Are lemon peels good for a garburator?

For the smell, yes: InSinkErator suggests citrus peels to freshen drain smells, fed in gradually. They don't remove the buildup behind the smell.

Can I clean a garburator with vinegar?

It won't hurt as a rinse, but InSinkErator, Moen and Waste King don't mention it, and with baking soda the two mostly neutralize each other. Never use vinegar with bleach.

Why does my garburator still smell after ice and lemon?

The smell usually comes from food buildup under the splash guard or grease in the grinding chamber. Scrub the splash guard by hand and use a cleaner tablet for the chamber. If the sink drains slowly, deal with that first: Moen says a slow-draining unit can smell on its own.

Will a cleaning tablet fix a clogged garburator?

A BLITZ tablet is made to clean and deodorize the grinding chamber. A clog is a drain problem and a jam is a motor problem, each with its own fix: see garbage disposal cleaner vs drain cleaner.
