Cleaning up yellowed/grubby plastic?

I spent the second half of 2002 in Norway (Troms?, in case anyone cares). I found myself missing peanut butter. I found there was a substance sold there as peanut butter, and it did bear a detectible resemblance to peanut butter - in fact, it was more or less identical to the homogenized peanut puree, doped to within an inch of its life with emulsifiers and preservatives and such until it requires a discerning tongue to detect the peanuts in its ancestry, that is sold in the cheaper and lower-class stores in North America. I did not, alas, find anything like real peanut butter (which to me means "ground-up peanuts", preferably ground up at the time and place of sale - while a bit of salt is an acceptable adulteration, I draw the line at anything further). I was told that the Norwegian appetite for peanut butter is almost entirely driven by the curiosity which TV depictions of peanut butter induce in Norwegians who inflict North American TV on themselves, and that after a few brief experiments, practically everyone abandons it. And, to be honest, given the substance that is presented to them under the name of peanut butter, I really can't blame them. To what extent this sorry state of affairs is representative of Europe at large, I am not competent to say. (Indeed, from personal experience I cannot speak to more than Troms?, though what I was told does seem to indicate it's representative of Norway.) /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse(a)rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
