Scavenging and neutralization of HCl from the exhaust plume of a solid grain rocket motor is achieved by including elemental magnesium as the sole metallic component. The magnesium acts both as a propellant fuel and as a scavenger of halogen acids derived form the halogenic oxidizer. Combustion of the high energy propellant produces an exhaust plume from which the halogen acids are scavenged.
