Soap making
Caustic soda can be used in soap making as a base, through a process called saponification, caustic soda when in contact with fats/oils results in soap. The caustic soda can be mixed carefully with water to produce lye water but precaution must be taken as this reaction releases heat and then the lye water can be combined with the relevant oils. Let the soap rest for 24 hours to harden.

Toilet/ Drain cleaner
Caustic soda has the ability to dissolve fats as it gets washed away with the solution which in turn rids the pipe of any grease. Hair can also clog the drains, but caustic soda easily hydrolyses the protein in hair which can help keep the drains clear.
Add 25g of caustic soda to 1 litre of water and stir gently with a wooden spoon. Do not use these containers and utensils for any cooking-related purposes later on. Avoid using your hands to stir the mixture.
Slowly pour into the drain, leave undisturbed for 30 minutes then rinse with 4 litres of boiling water. Repeat if necessary.
