The clear coating is called conformal coating.
I guess you've found out that there are different kinds of conformal
coatings,
silicone and urathanes. I have used Zip-Strip, a paint stripper, and it
'does not'
remove any markings from the IC's. The conformal coating bubbles up.
Use running water to wash the board off.

I took apart a UPS, and the PCB, including a significant portion
of the components on it are coated with some kind of clear and
shiny lacquer. This is nice for some things, but now I can't read
the markings on the chips. What kind of cleaner is best to clean
the coating from the chips?
