Hi
I only want to tell you 1 kilo 35% H2O2 costs 4eur and some cent here.
if anyone wants to regenerate his cucl bath "fast".
i assumed it much more expensive but today i had some spare time and went
to a shop for chemicals.
they also didn't ask any questions (somebody sayd there are problems
sometimes).
see no reason for running a bubbler and long time regeneration plus longer
etching times.
i also bought methylorange, 100ml solution 11eur... will last for a
lifetime.
regards
stefan
