Yup. it's Stabilant 22, manufactured by DW Electrochemicals in Ontario, Canada.
It's some sort of polymer that conducts but only in a real thin film. Seems to take several years to wear off contacts. Stabilant 22 is the straight stuff that you blend with alcohol yourself, Stabilant 22A is pre-blended with alcohol.
Since it takes an incredibly tiny amount to do its thing, a 50 Ml bottle will last you a long, long time. I apply it with lintless swabs or with a small diabetic-type of syringe.
It doesn't work for long on switches that carry power as the arc when operating fries the stuff off. It does work great on bandswitches, meter switches and worn-out carbon pots. It's kind of slimy, like silicon oil so it lubricates nicely. I use it on computer cables, switches, wipe down the contacts on computer memory boards, and it's terrific in automotive applications. It really is a contact enhancer, working in a similar way to mercury-wetted contacts.
