Deoxit Gold...Not Just For Tubes?

It's clearly not just for tubes and says so on the literature that comes with it. I use it a couple of times a year, but to tell the truth, I really dislike the sound of the system right after I use it. I just do it for maintenance purposes.

That's why I mentioned the old tubes with steel pins cleaned to "gleaming". A couple of the tubes I've gotten like that were absolutely shrill and unlistenable - very out of character from what I had come to expect of an RCA. One set was RCA 12AY7 black plates, another was RCA 12AX7 gray plates. 

Helps with PC connections.

Thanks for the feedback! I will start applying and see where it takes me.

Hi, first post here; I used Deoxit Gold G100L (100% solution in a glass bottle) and it was a bad experience. I carefully applied a small quantity of liquid as for instructions on all my gold plated connectors on interconnects and speaker cables. I wiped off with a clean soft paper and I was shocked for the result. The sound became harsh, bright in a negative way, cold, thin, coarse. I waited some days for a change, but the sound remained the same. On Naim forum I read of other people that had similar experience with 100% solution; so I cleaned two times all connectors with IPA (isopropyl alcohol) 99,9% and the sound came back as pre-Deoxit. The same experience on the audio system of a friend of mine. My advice: if You have high quality connectors plated with gold or rhodium, please don’t use Deoxit Gold G100L, just use IPA one or two times every year. Stop. If You have oxidized connectors no contact cleaner or contact protector will help; the solution is just change the connectors. Technically, Deoxit Gold is an insulator with a dielectric constant of 2.3 (similar to polyethilene); as we know an insulator can not increase conductivity. On their pdf papers Caig speaks of quantum tunnelling as the ’magic’ that permit to an insulator like Deoxit Gold to decrease contact resistance...but in this way of thinking the same apply to the oxide barrier on top of which the Deoxit Gold is applied. They don’t explain in details.
