The answer to 'how to clean garbage disposal' is to regularly clean and maintain your garbage disposal to keep it running smoothly. This involves running it with water and baking soda or vinegar, and occasionally using a disposal cleaning tool or brush to remove built-up grime and debris.
To clean your garbage disposal, first run it with hot water for a minute or two to help loosen any debris. Then, pour in a handful of baking soda or a cup of vinegar and let it sit for a few minutes before running it again with hot water. You can also use a disposal cleaning tool or small brush to scrub the inside of the disposal and remove any stuck-on food or grime. It's recommended to clean your disposal this way every 1-2 months to keep it functioning properly.
