Abstract
A process for rapidly etching and cleaning dental metal castings which result in a saving of time to the dentists of as much as 1000 percent as compared to prior art methods. A bath combining both etchant and cleaners is applied to the dental casting and agitated ultrasonically. A deplating current is simultaneously passed through the casting and the bath to further increase the rate at which the cleaning and etching process may progress. This procedure results in a combined cleaning and etching process which is faster than was possible previously for either process alone.
