[R-390] Current thoughts on washing

[quartz55]

I have this stuff called '8070 Electrical 88' made by 'Crown'.  It must be really ancient, and there's not much left in the can.  But I use it on anything that needs cleaning, water displaced, etc.  It says on the can 'displaces water and moisture, improves electrical properties, prevents corrosion, protects metal, lubricates'.  I've got no clue what it is, but it works wonders on switches and even slug tuned coils.  I wish I could find some more of it.  Comes out of the spray can and seems to sort of foam up and then evaporates and leaves a slightly greasy/silicone feel to it.  It hasn't melted anything yet.

But I'm sure that's not going to be much help.  I just thought I'd relate.
