hai
if i want to remove silicate scale with acid or base week
what must i do?


what coumpound of chemical can I uses?????

thank's alot

Where is it and how severe is the deposit? What sort of substrate is the
silicate deposited onto, and what is the actual form of the silicate?

I think you can probably see where I'm headed.

The simplest answer is to use hydrofluoric acid, but that is a dangerous
application.

Automobile radiator shops can sometimes remove silicate deposits with
a hot high alkalinity bath.

The answer, if a good one exists, would depend upon the conditions.
