playpen,
I have just done very similar cleaning only last night on my Dual . I took out the headshell , disconnected the 4 delicate wire leads from cartridge pins , Deoxit with N5 type first then with 100 % solution to clean all 4 pins of cart, and the 4 brass clips of lead wires ( I used thin paint brush to apply it within the tiny holes), left them overnight for chemical actions of corrosion removal. Now since you mentioned , I will even clean with toothpick . It is kind a difficult to clean the inside surface of "clips" which is the real contact area. Then apply Deoxit Gold with brush. I did not thought of cleaning the " stylus tube", but will sure clean it tonight before reassembling it tomorrow.
