Chemical drain cleaner is the sugary cereal of plumbing: heavily marketed, briefly satisfying, quietly destructive. The clog is almost always hair and soap scum in the first two feet, or gunk in the P-trap โ both reachable with tools that cost less than one bottle of the caustic stuff.

Scan It FreePull the stopper (bathroom sinks: unclip the pivot rod under the sink first; showers: unscrew or pry the cover). Feed the barbed strip down, twist, pull. Brace yourself for what comes up โ that hair rope was your clog.
For grease clogs in kitchen sinks: a squirt of dish soap and a kettle of very hot (not boiling into porcelain) water dissolves what the zip tool can't grab.
Sinks/tubs want a flat-cup plunger, not the toilet flange type. Block the overflow hole with a wet rag for real suction. A dozen sharp pumps.
Bucket under, unscrew both slip nuts by hand or with taped pliers, dump the trap. Kitchen traps hide grease plugs; bathroom traps hide toothpaste sludge and the earring you lost in March.
Feed the drum auger into the wall pipe, crank at resistance, work through, pull back the debris. Rent a longer one for main-line-distance clogs.
Hair catcher in every shower ($5), no grease in the kitchen sink ever, monthly hot-water flush. If multiple drains slow simultaneously, that's a main line issue โ scan the symptoms with SpotFix AI to confirm before anyone sells you a $400 'hydro jet.'
