Never use a plunger if you have already poured commercial chemical drain cleaners into the sink, as the hazardous material can splash onto your skin and eyes.
Avoid using boiling water if you have PVC pipes, as it can soften the plastic or loosen the glue at the joints; use hot tap water instead.
Wear rubber gloves and eye protection when handling clogs or using chemical cleaners to protect against bacteria and caustic splashes.

Steps
1
Prepare the area by putting on rubber gloves and safety goggles. If the sink is full of standing water, use a bucket to bail it out until only 3 to 4 inches remain, which provides the necessary suction for plunging.
2
Remove the drain stopper by twisting it counterclockwise, pulling it upward, or using a Phillips #2 screwdriver to unfasten it. Use a paper towel to wipe away any visible hair or soap scum from the stopper.
3
Block any overflow holes or secondary basin drains with a wet rag to ensure an airtight seal during the plunging process.
Tip: If you don't block these holes, air and water will escape, making the plunger ineffective.
4
Place the flat-bottom plunger firmly over the drain to create a tight seal. Plunge up and down vigorously for 20 to 30 seconds, then pop the plunger straight up to break the seal and check if the water drains.
5
For moderate clogs, pour 1 cup of baking soda down the drain, followed by 1 cup of white vinegar. Cover the drain with a stopper or rag and let the mixture sit for 15 to 30 minutes before flushing with hot water.
6
If the clog persists, place a bucket under the P-trap (the U-shaped pipe under the sink). Use an adjustable 8-inch wrench or slip-joint pliers to loosen the slip nuts and remove the trap to manually clear any debris.
7
For deep blockages, insert the tip of a plumber's auger into the drain or the wall pipe. Crank the handle clockwise to feed the cable until you feel resistance, then rotate the auger to break through the clog and pull the cable back out.
8
Reassemble the plumbing by replacing the P-trap and tightening the slip nuts securely. Run hot water for several minutes to test the flow and check all connections for leaks.
9
If none of the manual or natural methods clear the blockage, call a professional plumber to avoid damaging the pipes with excessive force or improper tool use.
Pro Tips
Install a mesh drain screen or hair catcher to prevent debris from entering the pipes.
Regularly flush drains with hot water to prevent soap scum and grease from solidifying.
