Mark,

We use a Westkleen Trition model board wash.  We have been using Loncoterge.  Have you
had any experience with this?  What is your opinion?  Or could you suggest anything
better?  We primarily use Kester pastes/solder.  Engineering tells me that we wouldn't
need saponifier at all except for one board which uses a very active flux.

Also, I have another question:  In our rinse cycle we have been getting cloudy water &
a residue that kind of looks like apple sauce ( I wouldn't dare taste it to see if it
is apple sauce thou. ;)  I know we need to get a sample sent out for analysis to
determine what it actually is, but have you ever experienced anything like this?

Thanks in advance,
Rob Watson
