What drain cleaning actually fixes

A clog almost always traces back to one of three places, and where it sits tells us how to clear it. Kitchen lines slow down from cooked grease and food that cools and hardens on the pipe wall. Bathroom drains (sinks, tubs, showers) clog from hair, soap, and toothpaste building into a mat. A main line that backs up, where more than one fixture gurgles or drains slowly at the same time, points further downstream, often to the sewer lateral that carries waste out to the street.
We start by figuring out which of these we are dealing with before we run any equipment. A single slow sink is a local problem. Several fixtures backing up at once, or a toilet that bubbles when you run the washer, is a main-line problem, and the two get handled very differently.
