OK - DeOxit as a contact cleaner (there are several formula) contains 95% volatile hydrocarbons and propellants if applicable, and 5% proprietary ingredients. These latter may or may not be Oleic acid, but they are reactant with various oxides of common conductive materials such as silver, copper or tin.

As long as all or part of that 5% has not reacted with one or another oxide, it will remain active. The salts produced by its reactions are, emphatically, conductive. DeOxit *MUST* be removed from whatever it goes into in order to prevent down-the-line problems. If used on a pot, the pot should be rinsed in a _lubricating_ cleaner. CRC, amongst others, makes such a material, spray or pump.

So, use DeOxit. Allow it to work while exercising the pot (or switch). Rinse & lubricate. Done.
