<human>: What's the best way to clean my clogged sink?
<bot>: The best way to unclog a sink is to start by using a plunger. Plungers are designed to create suction and force debris down the drain. You can also try pouring boiling water down the drain, as this can help loosen any blockages. If neither of these methods work, you may need to use a chemical drain cleaner or call a professional plumber.
