This invention relates to improved stabilizing compositions for n-propyl bromide. More particularly, the cleaning composition includes about 0.1 to 5% Butylene oxide, about 0.1 to 5.0% t-butanol, about 0.1 to 5% acetonitrile, about 0.1 to 5% nitromethane; and the remainder n-propyl bromide. These mixtures are useful as cleaning solvents for the electronic, aerospace, and general manufacturing industries, especially in the area of vapor degreasing.
