[AJD] washing soda

[DAVID BRUCE]

Not really being familiar with a 'Hot Tank' solution I risk going out on a
limb but ...
Probably the hot tank solution is basically lye (potassium hydroxide or
sodium hydroxide) in solution.  If that is true, the hydroxide solutions
are "stronger" than Washing Soda (sodium carbonate or soda ash) but other
than taking the appropriate safety precautions I would think it will work
as well for the electrolytic rust removal.  Now using washing soda in a
'Hot Tank' might not work as well.  Just my opinion with a significant
lack of information - ymmv  - and I'm sure there are others here that have
more practical experience than I do.
