Caustic soda drain cleaners

Concentration and formulation matter

Raw chemical crystals and formulated consumer products are not interchangeable. Mixing, dissolving and heat generation can create splash and burn risks. Prefer a clearly labelled product with controlled dosing over improvised chemistry.

• Concentration and physical form
• Heat-generation warnings
• Pipe and fixture exclusions
• First-aid and spill instructions

Consider a mechanical method first

A removable trap, plunger or correctly chosen hand auger often provides a direct way to address a local obstruction without leaving corrosive material in standing water. If an engineer may need to attend, they must be told what has been added.

• Access to the trap
• Presence of standing water
• Whether a solid object may be involved
• Likelihood that the problem is beyond the fixture

3. 3

   Read all hazard and first-aid information

4. 4

   Use only the stated dose and equipment

5. 5

   Secure the remaining product in its original container
