<human>:  How do I unclog a drain without using resorting to chemical solutions?
<bot>: The most effective way to unclog a drain without using chemical solutions is to try using hot water and a plunger. Begin by running hot water down the drain for several minutes, then use a plunger to loosen up the clog and help it pass through the drain. If that does not work, try using a drain snake or a wire hanger to loosen and remove the blockage.
