[Heathkit] cleaning wafer switches

[GARY HATTAWAY]

I've followed with interest the posts here warning of the dangers of Deoxit. I've been using it daily for almost three decades servicing all types of communications gear from broadcast to ham gear to land mobile radio to avionics and it has yet to cause me (or anyone I know) the sort of problems described in earlier posts. I've run into the same symptoms described, and heard the horror stories, but usually found a deeper issue with gear that was diagnosed as having "deoxit syndrone". Almost invariably, the switches, pots, relay contacts, etc were previously contaminated with or exposed to some other unsuitable solvent. This is in no way meant to offend and I hope none is taken, but I know of many equipment manufacturers who specifically endorse the use of (and even supply) Caig products as service aids for their products, and none that would endorse the use of brake cleaner.
