<human>:  How do I unclog a kitchen sink?
<bot>: To unclog a kitchen sink, start by making sure the sink is clear of any debris. Next, fill the sink with hot water, and use a plunger to loosen the clog. If the plunger doesn't work, then pour a mixture of baking soda and vinegar down the drain, allow it to sit for fifteen minutes, and then flush with hot water. If the clog persists, you may need to use a commercial drain cleaner or call a plumber.
