Re: Liquid Rosin Flux
I've still got some of the fluxite brownish stuff as per that green tin, it really works well on old stuff and makes a satisfying sizzle. I'd agree it should be washed off with IPA though. The LA-CO stuff that farnell sells is similar in effect, cuts through anything.
Recently I had the flux from Rapid, sold as Stannol Rosin flux. It's not brilliant. Good for surface mount and bright components but hopeless with old tarnish. I used to have some Fry's Powerflow in the yellow tin; its aimed at plumbers I think. Viciously effective on old overheated joints. However I once removed an SMD processor from a board using it, forgot about it during an extended wait for a new chip from abroad, and when I came to it, the pcb pads had all gone green and took me an age to get it back to copper. I was always taught to wash a board after soldering, with trichloroethane in the old days and now IPA,no matter what method was used, and I still do on all but the cheapest repairs.

Re: Liquid Rosin Flux
Yes, we used to slosh Trico (Arclone) around on everything, in those innocent days
