I remember this stuff back in the 1980s. It came in spray cans as contact cleaner. One crew where I worked had 20-litre drums of it. We used to bath circuit boards in it. It got rid of dust, oil, water, just about anything. It could cure intermittent faults even. Technician in a can, some called it. But since it is unmerciful to the ozone layer, it was banned in most nations. (I have heard there is a thriving blackmarket trade for it though.) Has anybody found something that works as good as the ole TF?
