I suppose the correct answer is "it depends" [thank you Dewey], but... 

If it were my shop I would not allow it. My unsubstantiated thinking is that
if the saponifier is still on there after final rinse then what else is
still on there? Saponifier should be the easiest thing to get off so if it's
not coming off then I'd be concerned about other stuff.

Also what sorts of conductive paths (hi pot failures) will the saponifier
produce should this assembly see high humidity and temperatures?

Subject: [TN] Saponifier residue

May 5, 2008

I have the following question:  If a saponifier is used with a DI cleaning 
machine to clean PWAs and the cleaning does not remove all traces of the 
saponifier, is there any concern, including sugsequent exposure, to a humid 
environment?  Any technical reports on this subject?
