  I'm building with some yard sale Lego, and have several elements that have orange stains on them. If I had to guess, I'd say something seeped onto the bricks while they were in storage. At this point I'll probably bury them inside my MOC, but I'm curious to know if there is a method to unblemish white Lego elements?

  Maybe you can try with toothpaste and a toothbrush as toothpaste is one of the mildest polishers.
