The actaul composition was more closely guarded than thermonuclear devices but here is one recipe:

Up until the end of 1957 it was possible to choose freely what fuel you used. Mercedes, for example, relied on the following recipe: 45% benzene, 25% methyl alcohol, 23% aviation fuel, 3% acetone and 2% nitrobenzene. The remaining two percent remain a secret until this day. The explosive mixture was so aggressive that remnants left over from training and races had to be drained off and the engine rinsed out with conventional petrol. This was the only way to prevent the engine from suffering damage overnight!
Im wondering if the 2% had bromine in it or some other organomettalic
