Problem with Electrocleaning of Brass

A. You should do a water break test after the cleaning and acid cycle. If you still have water breaks, some oil or organic compound might be present which was not totally removed by your electrocleaner, so you probably need to add a preclean step by means of a vapor degrease w/approved solvent.

A. You should be using a soak & electro cleaner designed for brass. Cleaners for steel will tend to pull carbon out of the brass (too brutal). Acid will not remove it. Do not over-clean brass. Some experimentation may be required. Many times you can have no current on the electro cleaner and still run the parts through it. Contact a proprietary manufacturer. Many support this web site.

A. Hi Ahsan. Can we assume that you did electrocleaning with those three different chemicals and they were all designed for electrocleaning brass? There is nothing unusual that you are not mentioning, like deep recesses or burned on carbon deposits? The electrocleaning tank is not the initial step? You are doing something first like soak cleaning, ultrasonic cleaning, power washing, solvent cleaning, etc., so you are not overloading the tank with grease?

Thousands of shops successfully electroclean brass, so we need to know what is different about your situation. Remember that grease floats to the top of the tank and the parts therefore exit the tank with a coating of oil on them if the tank is not kept clean. Thanks!
