Contact cleaners/What's good?

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.

PS: Iso-propyl Alcohol is widely used in industry as a solvent, so it will definitely remove the major grunge on dirty equipment, but definitely not a good choice for tweeking important connections on your system.
