i supposed you could wash it in a mix of 1/4 pint of 90 % pure iso propionyl ) and a 1/2 tea spoon of WD 40 so it gets the finest film of light volatile oil possible as it will evaporate .I see. Thanks.
And what does the so inclined Forist do now, if he wants to make something like that workable and functional again?
Dismantle it, use penetrating oil, make it workable, degrease it with alcohol, dry it with warm air and reassemble it?

Years ago watch makers used 7/8 white spirit and 1/8 of 3 in one oil after degreasing the instrument in a Trichloroethylene (TCE) bath & then in trich vapours . They also used it in the bath when small ultra sonic cleaning baths came along . It is carcinogenic even if used in the refrigerated lip trich. baths. ( no longer used in most places )
I'd try a pure silicone oil and some isopropanol ... see if it mixes well and use that or a very fine grade lock lubricating powdered graphite once it's been isopropanol cleaned .
Don't get any of the isopropanol on the instruments crystal as it's likely to dissolve it or leave it badly frosted .
