Use caution when cleaning delicate models with high-pressure water
systems.
WARNING: Caustic soda may cause chemical burns, scarring and
blindness. Mixing it with water generates heat that could ignite other
materials.Take adequate safety precautions; always use nitrile gloves
when handling caustic soda and models soaked in it.
