Tom, here’s the results of a quick Google search. You figure it out. Google is your friend.
"Nasty stuff, I can’t tell you the number of RCA jacks that I have seen that once had Tweek on them and the chemical damaged....looking at the jacks under magnification looked like the gold plating had been "blasted" off the substrate...."
"The name was "Tweek", a contact enhancer distributed by Sumiko. I still have a sealed sample in the original syringe packaging. Be very careful using this stuff as tended to gum things up and/or caramelize when dumped in places like tube sockets."
What exactly is the relationship between Stabilant 22 and Tweek? I have read a lot about poor results using the old Tweek product, such as the Soundstage! review from 2003 where Bill Cowan says (about Tweek),
"When it was used between dissimilar metals, a thick layer of black gook built up on the metal surfaces, and this could happen within a very short time frame. This gook was very difficult and sometimes even impossible to remove completely -- I managed to destroy the RCA plugs on a fairly pricey pair of interconnects trying to get it off. Since then, I�ve stayed away from contact enhancers, although I have made use of the Caig Pro Gold. But Pro Gold is billed as a preservative rather than an enhancer, and I�ve never had a problem with it causing any kind of chemical reaction on metal surfaces. For straight cleaning, I use either isopropyl alcohol, or when confronted with badly oxidized connections, Caig�s DeOxit. In both instances, the cleaner is applied and then completely removed, rather than left in place like Pro Gold or the H2L solutions."
"The information I found on Stabilant 22 states, it is a,
amorphous-semiconductive polyoxyethylene-polyoxypropyline block polymer with a molecular weight of about 2,800"
"What the heck is that? In liquid form, it appears to be primarily Isopropoal alcohol and is then called Stabilant 22A. If you guys are having success with it, then Stabilant 22 or 22A themselves must not cause a detrimental effect when left in-place over long periods of time like Tweek did, and it must not degrade as some believe the SST and Quicksilver do. Is this because it is polymer based vs. the organic oils (I believe are) used in SST and Quicksilver? Do you use it in its concentrated form or diluted with Isopropol alcohol? Any performance comparisions with ProGold?"
