Human: What's the best way to clean a clogged drain? Assistant: 
The best way to clean a clogged drain is to use a plunger. Start by plunging the plunger up and down several times, then pour some baking soda down the drain followed by vinegar. Let it sit for about 15 minutes before rinsing with hot water. If that doesn't work, try using an auger or plumbing snake to remove any obstructions.
