We have several Tectronics tube-type oscilloscopes, and on several modules we are having noise problems when we operate any of the multi-buttoned pushbuttons. Our suspicion is that this is a problem with dirty contacts, and our plan is to spray in some contact cleaner. BUT!!!.... we want to use a brand and formulation of contact cleaner that will minimize future dirt pickup problems. (GC Electronics' De-Ox-Id product has been questioned here because of the oil that is in the cleaner formula. The argument, valid or not, is that this oil might attract dust and make the problem worse.)
Can any experienced "old heads" out there recommend a particular type or brand of contact cleaner that is known to perform well for uses of this type? We'd love to hear about existing "best practice", rather than guess and end up with more problems down the road.
