I would try to find out what the shoe polish is made of before
trying to remove it.  That said, I would guess it is composed
primarily of wax and carbon black.  You have been using mostly polar
solvents to remove what is probably a non-polar material.  I would
suggest you might have better luck with a solvent that is less polar
and better at dissolving wax, such as toluene or xylenes.  Of course
you need to use personal protective gear when using these solvents.
I hope this helps,
