How To Unblock Drain With Caustic Soda Link

When NaOH comes into contact with water, it undergoes an exothermic reaction (it generates significant heat). This heat serves two purposes: it melts congealed fats and grease, turning them into a liquid soap-like substance. Simultaneously, the extreme alkalinity breaks down the chemical bonds of the organic matter, essentially "digesting" the blockage and turning a solid plug into a liquid or sludge that can be flushed away.
