Caustic soda, also known as sodium hydroxide (NaOH), is a powerful alkaline chemical used to dissolve organic matter such as grease, fats, and hair that frequently cause blockages. While highly effective, it is also extremely corrosive and must be handled with significant care to avoid severe chemical burns or damage to your plumbing system. Safety First: Essential Precautions
Carefully pour down the drain. The reaction begins immediately – you will hear fizzing and feel heat. Cold water is critical; hot water causes violent splashing and toxic steam. how to unblock a drain with caustic soda
After the solution is poured, it must be left to work. A waiting period of approximately 20 to 30 minutes is generally recommended, allowing the chemical reaction to break down the debris. During this time, the drain should be left undisturbed. Once the allotted time has passed, the final step is to flush the system. One should pour a kettle of boiling water down the drain to wash away the dissolved organic matter and the residual chemical. This is followed by turning on the cold tap for several minutes to thoroughly rinse the pipes and ensure no caustic residue remains. Caustic soda, also known as sodium hydroxide (NaOH),
A: Baking soda is mild (pH ~8). Caustic soda is extremely alkaline (pH ~14). Baking soda works with vinegar for minor clogs; caustic soda dissolves grease and hair chemically. The reaction begins immediately – you will hear
