soap allows to dissolve fats in small droplets of soap (micelles). Surface tension arises from affinity to the surface, like oil still doesn’t like teflon pans, despite being hydrophobic. So no, you can’t find one size fits all liquid. (Aside from supercritical fluids, but they require pressures - and sometimes are used in dry cleaning! so this might be your answer)

I’ve gotten coke on my nvme drive, after dunking it in distilled water couple of times and drying at 60 it worked 👌 the main thing which might fry anything is the case when voltage controls from battery/wall get bypassed. The chips in production are washed with deionized water on some steps, no problem. The structural damage comes from 7v+ voltages and prolonged exposure. (But something like data integrity can go to shits, that’s just chance. P.s. Obviously, you can’t heat up or wash battery).

they get more and more electrons, which are weaker and weaker bound, thus form metals
