Soluble salt (ionic) contamination of steel substrates constitutes a major cause of coating failure. Cleanliness of a steel substrate is a key element in improving coating performance. This cleaning process achieves a ``zero detectable`` level of ionic contamination on steel substrates. Sodium bicarbonate-based blast media is applied to the substrate using equipment designed to impart increased kinetic energy to the soft abrasive. This soft abrasive blast is followed by a pressure rinse of 3,000--8,000 psig using deionized water. The result is an extremely clean substrate, free of detectable ionic contaminants.
