WD-40 is not, in fact, made from fish oil. It is a petroleum-based product, as the smell alone should tell people. (I am not blessed with the keenest sense of smell, but even I can tell that it’s not fish oil in that can!) It does have a number of uses around the house, but perhaps not as many as some chain emails claim.
Why do I care about WD-40? No reason. Just getting ready to go “fishing” soon, and since this product has the word 40 in its name, and it is rumored to be made from fish oil, just felt like linking to one of the most useful sites on the Web (snopes.com). Nothing fishy here.
