WD-40 is the universal organic solvent....I'll bet inorganic life could evolve on a planet that is 2/3 covered by the stuff. Simply great for getting the stickers off the back of ceramic dishes and such.....Hmmm, I wonder if WD-40 will be the necessary ingredient for nanorobots to evolve into macrobots? Perhaps WD-40 is what astronomers really should be looking for, not water. Also, less chance of an inorganic WD-40 based species coming to Earth and stealing all our water.
