How do you clean the vent on the side of the sink where dishwasher drains?

To clean the vent on the side of the sink where the dishwasher drains, first, ensure the dishwasher is turned off and unplugged. Remove any visible debris or buildup around the vent using a damp cloth or a soft brush. If the vent is removable, take it off and rinse it under warm water to clear out any blockages. Reattach the vent once it’s clean and dry, ensuring a tight fit to prevent leaks.
