<human>:  How do I clean a clogged drain?
<bot>: To clean a clogged drain, you will need to identify the cause of the clog. If it's a simple clog of hair or mild soap scum, you can use a plumbing snake or an auger to break up the clog. If the clog is caused by grease, pour a kettle of boiling water down the drain to dissolve it. You may also want to try using a chemical drain cleaner to clear the clog.
