EC7M is clean up solvent that can help to prevent white residue problem. It made from Orange shield. Good luck

we had a project like this once. switched to using "genosolve" chemistry (US source, expensive) in conjunction with a degreaser machine, works fine if you can spend the money.

White residue remaining after cleaning circuit board assemblies can be caused by a variety of chemicals and reactions. Rosin and water-soluble fluxes, circuit board resins and epoxies, component materials and other contamination all contribute to this complex chemistry. This paper discusses many of the sources of the residues that seem to be an ever-increasing occurrence.

In the past 20 yrs the solvent industry has gone through a great deal of change. In the early 1990s, CFC-113 and 1,1,1-trichloroethane were the workhorses of the industry. The Montreal Protocol to phase-out substances that deplete the Earth's protective Ozone Layer was implemented in the mid 1990s. After phase-out of the CFC solvents, the solvent industry fragmented to a variety of cleaning solutions. The electronics industry was a large user of CFC solvents and many of these applications changed to aqueous based cleaners (...) But those alternatives are now facing various problems: e.g. aqueous based cleaners use a lot of energy, require long drying times, use equipment that requires frequent maintenance, and require a large footprint; no-clean fluxes leave flux residues; and trichloroethylene and n-propyl bromide have toxicity issues. In response to these serious issues newer solvents and blends are being introduced in the marketplace
Flux spray coating on a PCB with uniformal thickness down to 5 microns, with clear edge definition and minimal overspray. Can coat large or shoot dots with the same jet.

cleaning is a full and important production step. But even with the so-called no-clean manufacturing, it may be that these components must be cleaned to avoid malfunctions
