Unlike standard alkaline cleaners that use bleach or lye to dissolve hair, sulfuric acid is an aggressive dehydrating agent. When it touches a clog, it literally sucks the water out of the organic molecules, creating an exothermic reaction. This generates intense heat that melts grease and fat while chemically disintegrating hair, paper, rags, and soap scum.
In the end, sulfuric acid drain cleaner is a monument to human ingenuity and hubris. It solves a problem by threatening to create ten worse ones. It respects no material, no safety warning, and no homeowner's confidence.

If a single application of sulfuric acid does not clear the drain, do not add more. A deep-seated blockage, such as tree roots or a collapsed pipe, cannot be solved with chemicals. At this point, the pipe is filled with highly caustic liquid, making it dangerous for a plumber to work on.
