I suppose it depends on what sort of materials are on the pcb's etc but

I would be trying some suitable solvent like acetone or white spirit.

More costly but probably less time involved. It would need some capital

expenditure for a cleaning bay too.



** Acetone and white spirit attack many plastics - plus the fumes are harmful.

PCBs that have solder flux all over them need to be washed in solvent ( ie denatured alcohol) after being washed in hot water .

FYI: I have often imagined a bath full of Freon agitated by ultrasonics as the perfect answer.
