I'm running across more and more components (e.g. tube sockets, coupling-cap leads) which have gold flashing or plating. A quick web search opened my eyes to the problems associated with gold-contaminated solder joints. I'm trying to find the best way to remove this layer so that I can assemble circuits which won't deteriorate after just a few months.
Some technical papers recommend repeatedly tinning and wick-wiping the surfaces, others recommend multiple passes through a solder pot to prepare the components for final assembly. I have been mechanically removing the gold flashing with a Scotchbrite pad or wire-brushing with a Dremel tool, but this is tedious at best.
Anyone know of a quick chemical means of stripping gold without damaging the substrate? I'm increasingly frustrated with the time wasted removing gold flashing, which seems to serve no purpose other than marketing hype.
