Hi All,
We're seeking a cleaning solution for our post cleaner, which is used after
HASL.  Our flux is "100% water reducible".  The many products available have
me somewhat confused: (Solvent vs. aqueous vs semi-aqueous) (defluxer vs
cleaner) (saponifiers) (flux residue & activator removal) (ionic
contamination removal).

Then a supplier told me that many of his accounts simply use store-bought
dishwasher detergent for HASL postclean.

I like this "simple solution" (literally), but I'd appreciate some TechNet
feedback on the subject- on or off-line.

Thanks,
Mark Hargreaves
