\"How<\/p>\n

Why should you clean your garbage disposal?<\/span><\/h2>\n

It\u2019s easy to overlook your garbage disposal; until it starts to stink or clog. Regular cleaning helps your unit last longer and keeps your kitchen from developing unpleasant smells.<\/span><\/p>\n

\u201cKitchen sinks are where all your important food preparation takes place,\u201d says Tony from <\/span>Homeworks Cleaning Service<\/span><\/a> in <\/span>Philadelphia, PA<\/span><\/a>. \u201cKeeping the garbage disposal functioning optimally and smelling fresh keeps customers happy and impressed with our cleaning service.\u201d<\/span><\/p>\n

Beyond odors, a dirty garbage disposal can lead to stubborn clogs or even damage the appliance. According to Yaqub Najimi of <\/span>Farmingdale, NY<\/span><\/a>-based eco-friendly drain product makers <\/span>TubShroom<\/span><\/a>, \u201cBuilt-up gunk can lead to overheating or complete shutdowns; which can be a safety risk if not handled properly.\u201d<\/span><\/p>\n

How often should I clean the garbage disposal?<\/span><\/h2>\n

A good rule of thumb is to clean your garbage disposal once a week if you use it frequently, or every two weeks if you use it less often. Regular maintenance can prevent odors and keep blades sharp; especially if you know <\/span>how to make homemade cleaners<\/span><\/a> to have on hand.<\/span><\/p>\n

How to clean garbage disposal: 4 expert-approved methods<\/span><\/h2>\n

Before doing anything, always turn off the power to the unit by unplugging it or switching off the breaker. As emphasized by several experts including Jessie Cannizzaro, a master plumber from <\/span>Wauwatosa, WI<\/span><\/a>-based <\/span>Milestone Plumbing<\/span><\/a>, \u201c\u201cPower down and avoid accidents by making sure everything\u2019s off before reaching inside.\u201d<\/span><\/p>\n

\u00a0Once the power is off, use tongs or pliers to remove any visible debris. Then you\u2019re ready for a deeper clean using one of these proven methods:<\/span><\/p>\n

\"Pour<\/p>\n

1. Ice cube + salt scrub method<\/span><\/h3>\n

Grinding ice cubes with salt is a powerful way to loosen and scrape away grime from inside the unit. \u201cPour 2 cups of ice and a handful of coarse rock salt into the disposal,\u201d says Rosanne Scott from <\/span>Premium Rooter Plumbing<\/span><\/a> in <\/span>Hutto, TX<\/span><\/a>. \u201cRun cold water and turn it on for 10-15 seconds. This safely breaks up grime.\u201d<\/span><\/p>\n

Carol Doak, owner of <\/span>Mini Maid Gainesville<\/span><\/a> expands on this by recommending: \u201cAdd 5-6 ice cubes, at least 1\/2 cup of salt, and a cup of white vinegar. Turn on the disposal and run with cold water for 1-2 minutes.\u201d She also advises scrubbing the splash guard with dish detergent and a pot brush afterward.<\/span><\/p>\n

Natalie Hernandez, showroom manager of <\/span>High Touch Remodeling<\/span><\/a>, located in <\/span>Los Angeles, CA<\/span><\/a>, also endorses this method. \u201cDrop in a few ice cubes and a handful of coarse salt, then run the disposal with cold water for 30 seconds. Finish with a slice of lemon or splash of white vinegar.\u201d<\/span><\/p>\n

2. Lemon and citrus peel method<\/span><\/h3>\n

For a fresh scent, citrus fruits are a go-to <\/span>kitchen cleaning hack<\/span><\/a> that naturally deodorizes your garbage disposal.<\/span><\/p>\n

Jamie Coppock of <\/span>Black Rok Kitchen Design<\/span><\/a> shares their take on this method. \u201cPut a few small ice cubes and run it for a few minutes. This will sharpen the blades. Finally, a few squirts of lemon juice in the garbage disposal will freshen everything up.\u201d<\/span><\/p>\n

Natural living blogger, Marlene Campanale of <\/span>Every Purpose Home<\/span><\/a> in <\/span>Nashville, TN<\/span><\/a> offers a creative twist. \u201cFreeze distilled white vinegar and a few drops of lemon essential oil in ice cube trays. Place 2-3 of the frozen cubes into the disposal, sprinkle in a generous amount of baking soda, and pour warm water over everything. Let that fizz undisturbed for 5 minutes; the ice cubes scour the blades and the baking soda\/vinegar finish lifting the grime.\u201d<\/span><\/p>\n

\"How<\/p>\n

3. Vinegar and baking soda fizz method<\/span><\/h3>\n

One of the most popular answers to how to clean garbage disposal is the fizzy reaction of vinegar and baking soda. It breaks down stuck-on food and neutralizes odor.\u00a0<\/span><\/p>\n

Jim Allen from <\/span>Speedy Appliance Parts<\/span><\/a> in <\/span>Corydon, IN<\/span><\/a> instructs, \u201cPour half a cup of baking soda into the drain, followed by a cup of white vinegar. Let it sit for 5-10 minutes, then turn on the disposal and flush with hot water.\u201d<\/span><\/p>\n

Tim Kariev of <\/span>San Diego, CA<\/span><\/a>-based <\/span>SpeedMates Home Services<\/span><\/a> agrees, adding, \u201cThis not only neutralizes odors but also helps remove buildup inside the unit.\u201d<\/span><\/p>\n

Thunderbird Plumbing Victoria<\/span><\/a> also follows the same method, \u201cPour a half cup of baking soda down the drain, followed by one cup of vinegar; let it fizz for about 5-10 minutes. Rinse with hot water.\u201d<\/span>
\n<\/span><\/p>\n

However, keep in mind that hot water alone is not effective at clearing gunk, especially when grease is involved. Cold water should be used during grinding to prevent soft fats from melting and coating the pipes. Use hot water only during the final rinse, once debris is already loosened.<\/span><\/p>\n

4. Flush with a cleaning pod or product method<\/span><\/h3>\n

Cleaning pods can simplify disposal maintenance, especially when you\u2019re short on time.<\/span><\/p>\n

Gina Brooks from plumbing repair manufacturer <\/span>Danco, Inc<\/span><\/a> suggests, \u201cDrop a Liquid Rhyno Garbage Disposal Cleaning Pod monthly into your disposer, run warm water for two minutes and let it sit for an hour. These pods are formulated with a premium blend of supercharged bacteria and are infused with a fresh lemon scent.\u201d<\/span><\/p>\n

Renuv<\/span><\/a>, an eco-friendly appliance cleaning solutions company in <\/span>Hilton Head Island, SC<\/span><\/a>, recommends a similar routine. \u201cRun warm water, drop in a Renuv pod, and turn on the disposal; it foams up to scrub away grime and leave behind a clean, citrus scent.\u201d<\/span><\/p>\n
