I've used both of these.  Started with FeCl, switched to CuCl (made
from HCl+H2O2).  Why?  First, FeCl is getting hard to find locally.
Second, FeCl stains.  Third, CuCl can be air regenerated, so there's
less to throw away over time.

Neither of those are see-through, but I do put a strong light behind
the tank and can see enough.  I usually remove the board, rinse, and
inspect with a mag visor anyway.
