Does baking soda and vinegar actually unclog a bathroom sink?

Yes, for slow drains caused by soap scum and minor buildup. Pour 1/2 cup baking soda down the drain, follow with 1/2 cup white vinegar, wait 15 minutes, then flush with boiling water. It will not dissolve hair clogs — those need mechanical removal with a zip tool or disassembly of the P-trap.

How do I remove a hair clog from a bathroom sink without taking the drain apart?

Try a plastic drain zip tool (also called a drain snake or hair grabber) — insert it into the drain and pull back the barbed edges to catch hair. For most bathroom sinks, 3-4 passes remove 90% of clogs. If that fails, the P-trap under the sink needs to be opened.

How do I open the P-trap under the bathroom sink to clear a clog?

Place a bucket under the trap. Unscrew the two slip nuts (hand-tight or a light wrench) holding the curved pipe. Slide the trap off and dump the contents into the bucket. Clear debris from inside the trap and from the pipe opening in the wall. Reassemble by hand-tightening the slip nuts — do not overtighten or the plastic threads crack.

Can I use chemical drain cleaner in a bathroom sink?

Avoid it. Chemical drain cleaners (Drano, Liquid-Plumr) damage PVC pipes over time and create toxic fumes in a closed bathroom. They also leave a residue that makes future clogs more likely. Mechanical removal — zip tool or P-trap disassembly — works better and does not damage your plumbing.
