Removing SUP705 with Caustic Soda

Soak 3D prints in a 1-percent solution of caustic soda (sodium hydroxide) to
remove support material from difficult-to-reach areas and to give the 3D print a
smooth, clean finish. The amount of time you soak the 3D prints in the solution
depends on how delicate it is and how much support material needs to be
removed, but it is typically between half-an-hour and several hours. In any
case, you should remove as much support material as possible before the
caustic soda treatment, and rinse the it thoroughly (with a water jet) afterwards.
Warning
Caustic soda may cause chemical burns, scarring and blindness. Mixing it
with water generates heat that could ignite other materials. Never pour
water into caustic soda. When diluting the solution, always add caustic soda
to water. Take adequate safety precautions; always use nitrile gloves when
handling caustic soda and 3D prints soaked in it.

under running water afterwards.
SUP706 will dissolve into the caustic soda and sodium metasilicate solution
and saturate it, reducing its effectiveness. Replace the solution when the
support material reaches 15% of the solution (after approximately one
month of average use).
