Deoxit for cables

How can cleaning contacts which, for me anyway, allows signal to get through, dull that signal? Do people actually think signal is transformed by simply allowing it to be signal? Is it more "signally?" 

theoretically it should help complete the mechanical connection and prevent oxidation/etc occurring.  hopefully making the connection even better for current and voltage transfer and over a longer period of time, which is sort of "better or more signally".

I think applying the term "theoreticaly" to a statement of the obvious (Contact cleaners clean the contacts. Who knew?) shows a clear disregarding of irony. Yping, you are an Irony Dodger.

Perhaps the Caig ProGold G5 Connector Enhancer is a different type of product than Deoxit 100 or D5 Deoxit. Are "connector enhancer" and "cleaner" synonyms?

It’s all explained on the Caig web site, fortunately. You know, Caig dot com.
