How to unclog a sink drain?

Alright, I’ll give it to you straight—how I’d say it after years on the job. Slow bathroom sink? It’s almost always hair and gunk, nothing fancy. Here’s exactly what I’d do, in order: First thing—pull the stopper out. Most people skip this, but that’s where the problem usually is. Hair wraps around it and builds up with soap and toothpaste. Lift it out or twist it loose You’ll probably see a nasty clump—pull that out Rinse it, put it back, test the drain Honestly, that fixes it more than half the time. If it’s still slow: Grab a kettle and pour hot (near boiling) water down the drain. That helps melt soap buildup sitting further down. Still not right? Next step is under the sink—the U-shaped pipe (P-trap): Put a bucket underneath Unscrew both ends (usually hand-tight) Take it off and clean it out Don’t be surprised if it’s full of sludge—that’s normal. That step almost always solves it.
