Warning: The following is for total OCD nutbags only:

I always clean my solder joints mechanically; then I "pacify" them with alkaline flux buster; then I coat the joints with a couple of applications of very saturated "natural" shellac.

Paul, there is something I wanted to ask you but have kept forgetting. When I apply your shellac cover trick, 
I noticed that with time (days) the shellac layer over the joint becomes bubbled, not smooth and semi transparent as in the beginning, but
develops  millions of frozen bubbles in it. They do not open up so I guess the air protection is still there but.... Is that normal? I use chemically pure isopropyl to dilute shellac into a very thick mix.
