BFG raised white letter

Just wondering if anyone has had the same issue as me. I purchased a set of BFG Radial T/A's from Jeg's and the raised white letters are anything but white. They are a light brown color and I can't get them white. I have tried just about everything including a SOS pad with no luck. Any other tricks out there.

Seems like a common theme with the BFG's lately, as there have been discussions about that here.
