What do you do when a clogged sink won't drain?

You need to first identify the source of the clog. If it's something that can be easily removed, like food particles or hair, you can try using a plunger. Otherwise, you may need to turn off the water supply and remove the trap underneath the sink. Once the trap is cleared, you should be able to unclog the sink by pouring some baking soda down the drain followed by boiling water.
