ABSTRACT:
A method and abrasive blast medium for cleaning contaminants from electronic hardware. The abrasive blast medium is a pure, water soluble alkaline salt of bicarbonates and carbonates. The particle size of the alkaline salts range from about 20 to no larger than about 300 microns in diameter. The Mohs hardness of the alkaline salt particles is no greater than about 5.0. The blast cleaning conditions employed to clean the electronic hardware are mild. Blast air pressures range from about 10 to about 50 psi and the medium flow rate ranges from about 1 to about 10 lbs/min.
