How to Clean Your Garbage Disposal

DIY and professional solutions to stinky, greasy, dirty garbage disposals.

Garbage DisposalA garbage disposal is a really nice kitchen appliance to have. It saves you from having to choose between scraps stinking up your trash can or clogging up your pipes. However, even if you are very careful about what kinds of foods you put down the disposal, you may still end up with odor problems. Here are some garbage disposal cleaning tips that should help.

Flush with Hot Soapy Water

One of the most common causes of odors in the garbage disposal and in the pipes connected to it is congealed grease. Even if you know never to pour liquid grease down the garbage disposal, a little bit of grease will sneak down the drain whenever you wash greasy dishes. You can help flush this grease away before it has a chance to build up by periodically flushing the unit. Simply fill the sink with a few inches of hot soapy water, then pull the plug and turn on your garbage disposal.

Grind Ice and Salt

Food can cause odor problems when it adheres to the blades of your garbage disposal. To clean and sharpen your blades, pour two cups of ice into the unit followed by one cup of rock salt. Run cold water and the garbage disposal until the ice and salt is all gone.

Scrub the Splashguard

Many nasty odors as well as germs can hide on the rubber skirt or splashguard between the bottom of the sink and the top of the garbage disposal. Get an old toothbrush and squirt some grease-fighting dish soap or other degreasing cleaner onto it. Then give your splashguard a good scrubbing. Don’t forget to scrub the back of the splashguard too.

Odor-Busting Options

After cleaning your garbage disposal to remove the source of bad odors, you can also give it a pleasant odor with one of these options:

  • Citrus peels
  • Baking soda & vinegar
  • Diluted bleach
  • Borax
