Can you clean a collector's knife with a stainless steel cleaner?
I have a lot of hunting knives collector / leaves I put on ebay and I wanted to know if cleaning the knife marks diminish its value?
Generally yes, it will. If the blades are oxidized or otherwise poor condition, perhaps it would be nice. \ In general, for any collection (coins, guns, knives, jewelry, etc) the patina on the surface is most desirable for collectors. They can take it away if they want a.

Transfats and cell membranes -- do the cells repair the damage? Or are the molecules forever "mutated" ?
http://www.fi.edu/brain/fats.htm
Studies show that the trans fatty acids we eat do get incorporated into brain cell membranes, including the myelin sheath that insulates neurons. They replace the natural DHA in the membrane, which affects the electrical activity of the neuron.
Trans fatty acid molecules disrupt communication, setting the stage for cellular degeneration and diminished mental performance.
Normal fatty acids have a natural curve to their molecular shape. When they fit together in vast numbers, enough space still remains so that the membrane has the proper structure it needs to function at its best.
However, if these same fat molecules are changed by manufactured food processes, or if they are heated for long periods – as in deep frying – they mutate into a form rarely found in nature. Now their molecules are straighter, narrower, and no longer have their original curved shape.
Yeah, cells constantly do recycle their membranes, so eventually those phospholipids will get used in vesicles or such. Also, i don't think changing the shape of a few phospholipids will affect it that much, unless the entire plasma membrane is in a different shape phosphlipid, which would screw up the fluidity of the membrane.
