Hey ~Kat...

Look at these two web page from the Sharpie / Sanford Company >>

Stain Removal - General page

Removal of Permanent Inks page.


For Painted/Varnished surfaces - they suggest cleaning with
Rubbing Alcohol.

Also they mention AMODEX Stain Remover;
can't find a web site for Amodex Products.

Good Luck!
