Carbolic acid soap has a leathery smell. It's mentioned several times (as the "scent of blue") in William S. Burroughs, where he remarks wistfully, "you can still get it, sometimes, in Mexico". HA! I say. Now, you can get it any place where Jamaicans shop, under the name "Carib Carbolic Soap". Got a bar, unwrapped, tossed it in my broom closet. Its strong deodorant properties neutralized the cat box, the trash, and half the apartment. (It's a BIG apartment.) Don't know if it's the same carbolic acid that was used in place of Phisohex, though....its smell is germicidal enough!
