Make Base (KOH) Baths to surface clean monoliths

[penguins4u2]

Before KOH bath submerging , need to pre-clean monoliths with ethanol & dry under vacuum.

• submerge in ethanol for ~ 5mins, repeatedly removing and resubmerging
• dry under vacuum at 100C for ~1hr

once dried, the monoliths are ready for KOH treatment.
