Human: What is the best way to clean a clogged sink? Assistant: 
The best way to clean a clogged sink is to use a plunger. Place the plunger over the drain and pump up and down several times, then remove it and pour a mixture of baking soda and vinegar down the drain. Let the solution sit for about 15 minutes before rinsing with warm water. If necessary, repeat this process until the clog is cleared.
