cleaning contacts with caig pro gold

I am going to clean all of my contacts during my time off for christmas vacation. I was wondering what is the best kind to use. You can get it in a spray bottle or you can get it with a brush applicator. I will be cleaning interconnects power cables and rca inputs. Any suggestions would be helpful, as I have not cleaned my contacts in a few years. I am hoping that by doing this I will get improved sound, thanks
Get the Craig D5 spray
Remember to wipe off any excess if you use the Caig Pro Gold.
All you want is a near invisible film. not a glob of liquid.
This is one of those times a very little goes a long way, and a lot is BAD.
Basically put a trace on the metal, then wipe it off with a paper towel, lightly, once. Done.
Clean with Deoxit first,then Caig pro Gold.Elizabeth is right,just a tiny dab will do it.Too much and it acts like glue.
