Sort of related question - I am experimenting with a batch cleaner for WS
flux removal. I am using DI water for the wash and rinse cycle. I have
not "blown off" the excess water, just placed the assembly in a dry
chamber. The assemblies have "water-spots" on them. Do you have any
experience with this problem? I heard of an additive but can not readily
find information or suppliers of such a product.

Thanks for your help.
