Stabilant 22 is the concentrate and the Kit as previously mentioned allows you to do a proper dilution with alcohol and is then referred to as Stabilant 22A. I use pure Isopropyl (99.9%) from Amazon. It is a proven contact enhancer used in avionics, NASA, auto industry, etc. It does have a detergent and lubricating action.
The alcohol evaporates very quickly leaving the Stabilant on your connectors, etc. I use it on every connection in my system. Using a very small brush is ideal. Overapplication is not the intent and will just waste the product. Nothing is equivalent or performs better.
Michael Dayton Wright invented Stabilant 22 and was famous for his XG10 Electrostatic Loudspeaker and so many other electronics and conventional loudspeakers. A brilliant fellow that I had the pleasure of knowing for many years. I believe that he held degrees in electrical, mechanical and chemical engineering from MIT.
As a sidebar trivia, he was the first to use black enclosures for his electronics! His family continues to produce Stabilant 22. There are a number of papers that detail its actions in great detail.
