The answer to 'garbage disposal maintenance' is to perform regular cleaning and inspection of your garbage disposal to keep it running smoothly. This includes running the disposal regularly, flushing it with hot water and baking soda or vinegar, and checking for any clogs or damage.
It's recommended to clean your garbage disposal once a month by running hot water and grinding up ice cubes or lemon peels to help remove built-up gunk and odors. You should also check the blades periodically to ensure they are not dull or damaged. If you notice any issues with the disposal, such as leaks, unusual noises, or slow draining, it's best to call a professional plumber to inspect and repair it.
