That has got to be the easiest cleaning of HOS I ever heard. Flux remover, who knew? Another product I have used over the years for my stereo equipment is Hosa DeoxIT D5S6 Contact Cleaner + F5S-H6 Fader Lube. I have no idea if either would dissolve HOS oil but "Fader Lube" and "TV Tuner Cleaner" sound similar to me. And it is available. But pricey. I was wondering why would we use electrical cleaning products on gummed up loco gears but I guess it is to avoid harsh chemicals that could ruin wiring or plastic parts.
