Or professional. I have given up trying to keep the glycerin inside my Autometer fuel pressure gauge.
I have disassembled it enough to drain the liquid but I would like to remove the film with a solvent.
Hot soapy water does not work, has anybody been successful at this?

glycerin is soluble in water and alcohol so if water ain't cutting it go to Alcohol. Methyl/Denatured even Rubbing (isopropyl) will work

Thanks for the suggestions. I'll let you know how it works.

Here's my report:
Soapy hot water and household rubbing alcohol just turned the glycerin to small globs of jelly.
So I tried lab type isopropyl and it still did not dissolve the glycerin but it sure did remove the lettering from the gauge face.
Lesson learned.
