Problems in Aluminum Brightener
We are running clad 2024 and 7075 aluminum through our brightener bath (Ardrox 1266). Problems we have sometimes seen include a green foam in the bath and parts rejected because they are too dark (stained?). This dark discoloration is very difficult to hand polish in order to remove. Any ideas about what might be happening?

To what business are you dedicated, why are you cleaning the aluminum, if you give more information on what you need, maybe I can have a new product that works for you.
