Vitamin C will also clear your blocked fuel injectors and, if you ask it nicely, will darn your socks for you.
Additionally, Pauling wasn't the only person, or even the first person, to win two Nobel Prizes (though he was the first not to have shared either of them, FWIW):
Since the establishment of the Nobel Prize, four people have received two Nobel Prizes:
Maria Skłodowska-Curie: in Physics 1903, for the discovery of radioactivity; and in Chemistry 1911, for the isolation of pure radium
Linus Pauling: in Chemistry 1954, for the hybridized orbital theory; and Peace 1962, for nuclear test-ban treaty activism; he "remains the only person to have won two unshared Nobel Prizes."
John Bardeen: in Physics 1956, for the invention of the transistor; and Physics 1972, for the theory of superconductivity; and
Frederick Sanger: in Chemistry 1958, for structure of the insulin molecule; and in Chemistry 1980, for virus nucleotide sequencing.
