You’ve cleaned out your refrigerator, taken out the trash, and checked under appliances for spills—but you just can’t seem to track down that odious smell coming from your kitchen. Your garbage disposal is the likely culprit. While garbage disposals offer convenient cleanup, food debris can get caught and mold can grow, leaving you with a less than pleasant odor. Here are three quick tricks to banish the smell.

1) Scrub the outside of your garbage disposal.

While most assume the smell is coming from inside their sink, the visible portion of the garbage disposal can catch small particles, and mold often grows where the flange meets the sink basin. Use a scrub brush, dish soap, and hot water to clean the area.

2) Make deodorizing ice cubes.

With just a couple of ingredients from your kitchen and an ice cube tray, you can make an easy DIY deodorizer for your garbage disposal. Chop citrus peels into half-inch sections and place them in an ice cube tray. Pour vinegar over the peels and let the cubes freeze. Grinding up the ice cubes will get rid of gunk, while the high acidity from vinegar will kill most bacteria and mold. The citrus adds a clean, fresh scent.

3) Banish odors with baking soda and vinegar.

For stubborn odors, turn to baking soda and vinegar. Pour about half a cup of baking soda into the smelly garbage disposal, then follow it with vinegar. The bubbling chemical reaction will loosen stuck food particles, while the vinegar’s acidity eats away at mold and bacteria. Allow the mixture to sit for 10 minutes, then rinse with hot water.
