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?

2I guess the first step would be to identify what the stuff actually is (the only idea that comes to mind being cat urine, since an unguarded box of small LEGO parts could be mistaken for a litter box by some); and then whether is comes of or not - I supposed you've tried regular cleaning options already? And are you sure it's orange spots, not simply sun-yellowed bricks?– JoubarcCommented Feb 10, 2013 at 21:00

1If it's really rust stains, oxalic acid may be worth trying...– PhiloCommented Feb 11, 2013 at 8:32

So far I tried a warm soapy water scrub with a soft toothbrush... Still have orange stains. Thankfully, there was no litter box aroma. I shy away from those yard sales. ;)– Major StackingsCommented Feb 11, 2013 at 23:32

Does it happen to look anything like this?– Ambo100 ♦Commented Feb 19, 2013 at 19:08

@Ambo100 Quite simular. Sorry, I should have posted an image. I'll do that soon.– Major StackingsCommented Feb 19, 2013 at 21:44

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