If it is cleaned of oil, you can use a magic marker or Sharpie.
DyKem is a layout fluid that dries to put a very thin blue
layer on a material to be marked with a scribe.
There is also hi-spot blue, which gives a non-drying film
that is easily rubbed off. But, it dyes skin and clothing
pretty badly. Also known as Prussian Blue artist's oil
pigment. Either of these should work for the purpose.
