Removing stain from nail polish remover off white paint ??

Thankfully it wasn't on my car but it is on a piece of car stereo equipment. I was removing an adhesive sticker that had been placed on top of it. That came off nicely but a few mintues later I noticed there is a slight yellow stain where I applied the liquid. Looking at the jar the fluid is slightly yellow in color itself.
The surface is flat and the finish is a shiny white and looks like paint on a car. I took some Mother's to it, I used the three step process, REMOVER / GLAZE / WAX .
This took a bit of the yellow out but its still there. It looks almost like the yellow residue from tabacco but lighter. I also tried rubbing alchohol [should have used that in the 1st place but found the other stuff first] and then bleach. Neither of which had any effect.
I thought nail polish remover was as harmless and rubbing alchohol ??
Any suggestions on how to get this off ?
