Abstract:
A method for cleaning a surface of an aluminum or aluminum alloy body by immersing the surface in a basic aqueous electrolyte formed essentially from dissolved trisodium phosphate, flowing DC current through the electrolyte and the body for cleaning, and then removing the body from the electrolyte. An additional cleaning step, which may include ultrasonic cleaning, may be performed to remove loose matter adhering to the body after the electrolytic cleaning.

Claim (Index 1):
A method for cleaning an aluminum or aluminum alloy body, the method comprising the steps of:\n (a) wetting the body with an aqueous electrolyte, the electrolyte comprising trisodium phosphate dissolved in water, the electrolyte having a pH generated by the dissolved trisodium phosphate alone without contribution from any other ions of between about 10 and about 10.5; (b) flowing current from a current source through the body and the electrolyte concurrently with step (a); and (c) stopping the flow of the DC current after performing step (b).
