(From WWI to Vietnam) A concoction issued with boots and boondockers intended to clean them, since the footwear was made with the rough side out (much like the modern Desert Boot). By the late 1950s, it was not being used; Marines were using bottles to force shoe polish into the nap so that the boots and boondockers could be spit-shined. This all came to an end when Defense Secretary McNamara forced Marines to give up their comfortable “Marine Corps last” footwear and replaced it with the Army Munson last which was much less comfortable, but cheaper.
