<human>:  How do I unclog a drain?
<bot>: To unclog a drain, start by pouring one cup of baking soda down the drain, followed by one cup of white vinegar. Let the mixture sit for 15 minutes before pouring a pot of boiling water down the drain to flush away any clogs. If this doesn't work, you may need to try using a plunger or a chemical drain cleaner.
