Caustic Soda - 500g


Caustic soda is a highly corrosive chemical traditionally used for unblocking drains, sanitising urinals and cleaning basins and sinks. It is extremely cheap and very effective.

Handling Caustic Soda

This powerful chemical cleaner and steriliser should only be used by trained operatives wearing the correct protective clothing, as it can cause severe burns. Suitable clothing includes thick rubber gloves and protection for the eyes and face.

Using Caustic Soda

Caustic Soda is the chemical Sodium Hydroxide in a solid granular form which dissolves in water. It should always be added slowly to water, never add water to caustic soda. A 500g pack makes 5 litres for clearing blocked drains. It can also be poured onto an oil stain on concrete. Scrub with a brush, leave for 30 minutes then rinse away with cold water.

Storing Caustic Soda

Caustic Soda should be kept in a cool dry place, locked and out of reach of children. It must always be stored in its original packaging and never be transferred to another package. The original pack has a child-resistant lid and also contains information for medical staff in the event of accidents.
