Contact cleaners/What's good?

Regular alcohol is not good because there's lanolin in it (an oil). Denatured alcohol is OK though; recommended on tape heads, pinch rollers, etc. so that's good for contact cleaning too. Pro Gold also contains an oil film, which, although it theoretically prevents contact oxidation, the oil helps attract dust accumulation into a connector & you really don't want that. Kontact or Audioquest Ultraconnect are both good & pure non-residue cleaners. Although I'm not for sure, I believe that Caig DeOxit is non-residue cleaner too - can anyone confirm this?

i've used both kontact and craig's pro-gold. i like the former better than the latter.

I have had excellent results with Kontact. I use it at least four times a year if not more often. I have not seen any build up.

Bob B & Lak & Randal are absolutely correct, I strongly recommend Kontak, no residue left behind. To my hearing much better sounding that Caig products in direct comparison I did.

I have only used Denatured Alcohol. Does regular alcohol really have lanolin in it?? Lanolin is used in skin cream and some people are allergic to it. I doubt that when you go the the doctor with a cut or they are cleaning the skin to give you shot, they would use something that could would be harmful to some patients. There are two types of "regular" alcohol. Rubbing alcohol which may be what Bob is referring to; and there is also Iso-propyl which has no additives in it. (50 cents a 12 ounce bottle at your drug store). I have used Iso-propyl in an emergency only when no denatured is available. Iso-propyl is what you would have used is science / chemistry class is school.
