Liquid for removing pencil from wood crevices

i carve wood jewelry and i have many different crevices with pencil
in them that can be removed with sandpaper, but i am looking for a
possible liquid to remove, nothing that i know of, works. Is there
such a thing??,

Can you not gently wash the marks off with water and a
toothbrush…maybe a tip of mild soap…

Why don’t you want to use sandpaper? Waterproof and thousandth grit
polishes at the same time.
