This is often the most effective first step. Ensure there is enough water to cover the cup of the plunger to create a proper seal.
However, it cannot pass through a . If water sits on top of the clog, the caustic solution will react at the interface, creating a crust of semi-reacted material that hardens and seals the blockage tighter. how to unblock drains with caustic soda
Fat + NaOH → Glycerol + Soap (water-soluble) Hair (protein) + NaOH → Water-soluble amino acid salts This is often the most effective first step
– After flushing, pour a cup of white vinegar down the drain to neutralize any remaining NaOH. Then flush again with cold water. If water sits on top of the clog,
Caustic soda (NaOH) is a strong alkaline chemical. In drain cleaners, it appears as dry white flakes, pellets, or a liquid gel. It works not by dissolving organic matter physically, but by creating a highly exothermic (heat-producing) chemical reaction that hydrolyzes fats, grease, and hair.
The following PPE is mandatory and must be worn throughout the entire process:
Unlike a plunger (pressure) or snake (mechanical), caustic soda works via:
