Mine do the same thing. I was assuming it was staining from some minerals in the water, and was actually planning on replacing them next year since they're fairly inexpensive.

I just think the get yellow with the choline, and age. You can try rubbing some vitamin c tablets on them to see if they turn white. It would not be worth doing an ascorbic acid stain treatment if that is the only yellow you have. Just crush up some vitamin c and put it in a sock and rub.
