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. Plungers are designed to create suction in order to break up any blockages that may be present in pipes or drains. You can also try using a drain snake, which is a long, flexible rod with a handle on one end and a brush on the other. Insert it into the drain and turn it in a circular motion to remove any debris that may be blocking the pipe. If neither of these methods work, you may need to call a professional plumber to help unclog your sink.
