Caustic soda

    'tother day I chanced to look in the back room of a local DimSum restaurant and saw bags and bags and bags of caustic soda - like a skid of it.

    What use would a restaurant have for hundreds of pounds of caustic soda? I looked it up on Wiki and found only two uses that make sense:
    - washing or chemical peeling of fruits and vegetables
    - most yellow coloured Chinese noodles are made with lye-water

    Still, hundreds of pounds?

    Well, I know caustic soda is often used to clean ovens. It removes grease well.
