I purchased two Steck castle walls from DS, and they were both
slightly discolored. They are a little bit brownish, rather than grey. It's really only noticable when they are intermixed with some mint condition Steck pieces I have.
My wife says I'm being too picky.

Nevertheless, I thought I'd ask....
Is there a way to remove this discoloration? If so, how?
I would imagine that this question has been answered on this forum, but I can't seem to find a thread about it. Perhaps I'm using the wrong search words....
