Tetrion Caustic Soda - 500g



Tetrion Caustic Soda is the traditional answer for clearing blockages in drains and pipes, and for heavy duty cleaning.


  • To unblock drains or pipes, add the contents of the tub to approx. 7 litres of cold water. Stir well.
  • Pour immediately and carefully down the drain.
  • After 30 mins, flush with boiling water. Repeat if necessary.

As a general cleaner:

  • Mix 1-2 tablespoons in approx. 5 litres of cold water and apply. Rinse after use.

Note: Caustic Soda must never come into contact with acrylic, aluminium or galvanised surfaces. Never use with any other cleaning chemicals. Avoid acids.
