You might try some navel jelly, no idea how well it would work on graphite, but it works on everything else.
the only two other things i know of, #1 Aqua Regia (a combination of nitric and hydrochloric acid) used for dissolving metals. isnt something you use without knowing exactly what your doing with it.
#2 i've been told peroxide can bleach out graphite, the purer the better, but i have no idea how long it would take. Also remember the purer the peroxide is, the more careful you have to be with it.
