Treated my interconnects with Deoxit D5 today

I go with the 'you used too much' theory. Any of these products brush on and WIPE OFF. if you can see or feel it IT IS TOO MUCH LEFT ON. What is really wanted is a few molecules thick left on the metal. not enough to be swimming in the stuff.If you just wipe everything off with a paper towel. gently, wiping a few times each area.. Should get you to the right amount left on.To reach INTO male RCA, I use a Q-Tip puling  most of the cotton off, then flatten it a bit so it will go in-between the barrel and pin. I would NOT try to clean inside the female RCA unless you slathered a lot into them. If so and need to clean in the female RCA, I suggest pipe cleaners.

I have been using Deoxit D5 cleaner and ProGold G5 Conductivity and Conditioning Enhancer for overs 10 years without any sound degradation. For future cleaning, I would recommend following kit that has everything you need to clean the contacts,

Glad to hear it Whitestix!
Nothing worse than having this horrible gut feeling that somehow you screwed your own system up!

Maybe as a few have said it was a simple case of if a little is good, more must be better!

Enjoy the music.

Uber,
Thanks, friend, for the comment. Maybe I put on the Deoxit a tad to thick, but it has now settled down to its former wonderful sound.  I am hearing sweet wonderful music again!  No good deed goes unpunished, in my case.  

If you feel you put it on a bit thick now is the time to wipe it off. I find Craig products v good but accept Stabilant 22 is probably best. When I run out of Caig Pro I’ll give Stabilant 22 a try; unless there’s some consensus that the Stabilant would make a difference :)
