 Jeep, For many applications the Ideal product will work just fine, and should do no harm.  It is a contact cleaner only, which is the function of the aliphatic hydrocarbons.  If you look at the material safety data sheet (MSDS) for Ideal #40 610 you will see that it contains only hydrocarbons and tetrafluoroethane, which is the propellant.  Caig products contain a proprietary material that will treat surface oxidation and any number of other contact ills.  The isopropanol is probably in Deoxit because it is required as a solvent for the secret stuff.  In my experience and yours too, Deoxit works, and works well but in many cases cleaners such as Ideal #40 610 will work just as well.  I typically just use Deoxit, but it would reasonable to first try the Ideal product, and if it does not work, of if the contact fails again before too long, then use your Deoxit - save the Doxit for stubborn cases.

Because the active ingredient in Deoxit products is a trade secret there is no patent or other technical information available on it,
but the company has some technical information that explains in a general way about how the stuff works.

I think that they keep the price pretty high because it works so well.  Deoxit is nothing like a lot of the stuff that is peddled for the audio guys, like thousand dollar power cords and AC receptacles  or electronic boxes that you can use to "break in" your speaker leads!

Contact cleaners today are generally hydrocarbon mixtures because the chlorinated hydrocarbons that used to be employed (like carbon tetrachloride and trichloroethylene) are health and environmental risks.  The hydrocarbons are safer in these connections, but they are flammable.  Incidentally, I make use of charcoal lighter for a lot of cleaning in my shop - it is a hydrocarbon mixture similar to kerosene, but with the smelly components distilled off, and it is cheap.

As an analytical chemist I would like to know more about the chemistry of Deoxit, but I am happy enough to settle for the fact that it works!

Rick, NN2K forwarded your note to me, which is why I am copying him on this.
