the goal is to salvage the pc boards complete so that maybe i can sort out enough
to reassemble one of the inverters.

so i guess i will go the alcohol route and a soft brissle tooth brush.

once clean and dry, i would assume i should coat them with something to protect
the boards and to aid in keeping further corrosion in check.

spray laquer, or is there a specific spray on finish to coat the boards?

also i need to make sure the two large transformers are clean and dry
i would suppose connecting them to some low voltage low current source
so that they can slowly heat up and assure they are dry.

how about some form of varnish to reseal them? maybe take them to a motor shop
to have them dipped?

i have tried to contact vanner service dept, but they have not returned my calls as of yet,, i suspect they really don't have much desire in supporting a 10 year old inverter.

thanks

It's called "Conformal Coating". The proper top-notch stuff we use for IS (intrinsically safe) mining gas monitoring equipment is not cheap. Most larger electronics suppliers will have some sort of aerosol lacquer (ask for Circuit Board Lacquer) for a reasonable price.
