They generate less heat than caustics but are more aggressive on stubborn inorganic scale like uric acid crystals (in toilets). Best for: Toilets and severe bathroom clogs. Examples: The Works, Liquid Fire (industrial grade). Pros: Dissolves toilet paper and organic matter instantly.

How they work: Caustic cleaners create an exothermic (heat-producing) reaction. When the granules or gel hit water, the temperature inside the pipe can spike to near-boiling levels.
