Jeff We have found that using a specific saponifier at 10% and a low pressure high flood cleaning approach at 145 F works very well at removal of the low residue (No-Clean) solderpaste residues and wave solderflux. This is done without brushing and works with a 2-3 min wash contact timing. We have rescue cleaned many a board this way. So it can be done. Contact me offline and I can give you the details.
