    Does anyone here have an ultrasonic jewelry cleaner? That would work nice too.

    As a trainee tech, I did that back in the 70's with some tubes for a Beckman Impedance Bridge .....The tubes were not at all impressed, nor was our Chief Engineer. Embarassed

    This was a stainless 18/10 spoon though with no oxides that the deoxit would dissolve - still  residue wise it was next to nothing - that little pink stain on the qtip was all that was picked up off the spoon.

    That spoon over the candle flame had me a little concerned for a bit there! LOL!

    Obviously, Roy, you were born with a silver spoon in your DeOxit.

    Those pics remind me of the Stones song Dead Flowers: "I'll be in my basement room with a needle and a spoon. And another girl to take my pain away. Take me down little Susie, take me down"

    286 deg C is the boiling point of light Oleic Acid at sea level (or whatever that trade-secret ingredient might be).
    829 deg C is the temperature of a paraffin-based candle flame.
    This method is not 'fractional distillation' - which would be necessary to separate two mutually soluble VOCs from each other. Otherwise, the lighter fractions can 'pull off' heavier molecules as they boil.
    Starting from a 5% initial concentration, the magic moment in any case would be very short indeed.

    Guys and gals - using DeOxit D5 in this application - TUBE SOCKET - is, to be as gentle as possible, contraindicated. But, do as you see fit.

    What's wrong with a little seriously de-natured alcohol (not the grocery-store grade) and a pipe cleaner?

    Not one little thing. I keep a set of miniature spiral brushes for the purpose - and use only 100% volatile solvents. Easier for small-pin tubes.

    Great minds think alike. Very Happy
    A caution, 80% (grocery store) de-natured alcohol has oils added to it. Not A Good Thing for tube pins or tape-heads. Metal to metal, nothing in between.
