[Boatanchors] Cleaning rotary switch contacts

[Jim Wilhite]

DeOxit D5 will wear off or evaporate in a few months, or has for me.  Good 
for a while but be prepared to re-do it.  I don't know about the Pro Gold, 
anyone have experience with it?

I use the D5 to clean the contacts then use denatured alcohol to clean again 
then apply a product called Stabilent.  I did a receiver with an oscillator 
wafer that was giving trouble about a year ago and haven't had to touch it 
since,  Just run the switch through its travel one time and it comes right 
in.

Stabilent is used on computer boards and other very sensitive contacts and 
all reports from industrial users are positive.  After redoing the contacts 
with D5 and Pro Gold for several years, I switched.  Others may comment on 
the Pro Gold as desired.  Stabilent is a concentrate that is mixed with 
alcohol at a 10:1 mixture and applied only to the contacts.  If you dip the 
switch in it, don't worry it is very stable as the name implies. It only 
remains on the metal contacts.  The product adheres to the metal and the 
alcohol evaporates.

Stabilent does not evaporate on metal as others do and coats the contacts 
with an enhancer to provide a low current path.

Not for high voltage contacts...meaning above 500 volts or so.
