Human: How do I fix a clogged sink? Assistant: 
Start by looking for any debris or debris buildup in or around the sink's drain. If you have found anything, use a pair of sturdy pliers or a drain snake to carefully remove it.  2 Next, turn off the water supply to the sink and remove the stopper. If the sink still remains clogged, use a plunger to create a vacuumed pressure and try to dislodge any buildup causing the blockage. 3 If that doesn't work, you may need to use a chemical cleaner. Make sure to follow the instructions carefully and wear protective gloves and a mask to protect yourself. 4 After that, pour boiling water down the drain slowly to help clear the last of the clog. Then, run some cold water for a few minutes to help clean the pipes.
