Aluminum etching solution can be used for both cleaning and inspection where an alkaline bath made of sodium hydroxide (NaOH) is typically used for cleaning or etching aluminum parts.

Aluminium chemical etching process 

The process involves etching aluminum parts to assess the grain size, prepare the surface for subsequent FPI (pre-pen etch) and detect surface defects.
