searched and oddly no threads with this as a title, hence the redundant phrases.
i've read in other threads about cleaning the high z areas with various flux removers, just isopropyl, or even acetone. IME, in line with others' here, is that the flux removers leave significant sticky residue (in spite of cleaning with toothbrush and multiple rinse cleanings, etc.), and isopropyl doesn't seem to leave the residue, but also requires a lot more cleaning iterations and brushing to break down the flux. i'm now interested in trying acetone, but only want a small quantity of it, just a few oz, and most drug stores seem to have added (a drinking deterrent?) denatonium benzoate. no idea what amount is included in the Walgreen's "100% Acetone" bottles...
can anyone comment on whether or not DB is problematic in this application? plan is to do a cleaning with isoprop after the acetone eats away the flux and hopefully nothing else, then finally a conformal coating and be done with it. if any seasoned folks have better methods they'd like to share, i'm all ears.
