What can I use to remove paint spots on statues?

[sith lord utinni!]

I got the GG dewback/sandtrooper statue the other day and I noticed that on the side of the base there is some black paint , atleast thats what I think it is. It isn't very thick either but noticeable. I was wondering if there was some kind of paint remover or other item I could purchase to clean off the black without harming the sand colored base. Any help would be greatly appreciated.
