D5 on interconnect connectors, speaker cables, and the 3 prongs on a power cable. And the connections on the components. Using a soft cloth, I clean the RCA jacks, XLR pins, speaker and amp binding posts.

I've never used a liquid on AC receptacles. Pulling the cable termination in and out to possibly better the contact is good enough for me.

Also, when I buy a tube, NOS or used, I let the pins sit in a bath of D5 liquid for about 15 minutes. Just enough liquid to cover the pins.

Thanks for the details regarding your experience using the D5.  

Personally, I never considered putting a cleaner into a female outlet (even one that is shut off at the breaker).  That seems to be asking for trouble.  More to the point, I am glad to know that you used it on the male, 3-prong plug.  That seems sensible.

One question: did you perceive an improvement or degradation ins sound-Q?

Cheers,

TBH, I've never sat behind my rack and treated the entire system as other members do. I kind of do it piecemeal so I'm not sure if I can hear a difference.. But the cleaner works very well. To answer your question, after cleaning the speaker cables and speaker binding posts I really believe there was an improvement in SQ. The cloth I used had some major black spots from removing tarnish. 

The Deoxit Gold coats the metal after cleaning and is said to increase conductivity. Many good reviews about this product. There are other contact enhancers that some members swear by.
