<human>:  Can you tell me the best way to unclog a sink drain?
<bot>: The best way to unclog a sink drain is to start off by pouring some hot water down the drain to loosen the clog, then use a plunger to force the clog out. If that doesn't work, a chemical drain cleaner may do the trick. You can also use a pipe snake to try and break up the clog before using the chemicals.
