Regarding the shine on the Oilzum fob, it was in very nice condition when I bought it, I think I may have rubbed it on a flannel cloth that had some residue from Simichrome polish. If fobs are very dull or dirty, I sometimes will use Simichrome and an old toothbrush to clean them. Just don't use the wife's. Everybody has their own favorite way,as in any hobby. Fobs are not as critical as coins. If it is one I may sell or trade, I don't clean it.
