Q. We are interested in a cleaner that will perform well for mixed metal ultrasonic baths. We are cleaning titanium and cobalt chrome. What can you recommend?

A. As a general rule, mixed metal baths should be avoided. When metals are far enough apart on the galvanic potential scale, batteries can form and the plating out of metal oxides can result, manifesting in dark deposits. This occurs when you clean active metals in electrical and electrolyte solutions in contact with another metal at a different galvanic potential.

Q: We have insect and proteinaceous residues we are looking to remove from an aluminum drum.  We know Tergazyme is the “go-to” for such things but we seem to get aluminum chelate blush.  Can you recommend something different?

A:  A chelate blush is a white crusty irregular deposit of aluminum edetate, a reaction between the aluminum and the chelating agent in some Alconox, LLC detergents. You are totally correct to try a protean enzymatic detergent.

Q: How can I ensure there are no residues left behind in the artificial heart we manufacture?

A: Swabbing for detergent and manufacturing residues (machining oils, particulate, etc.) is a validation standby.  If you cannot swab the interior of the artificial heart, then we recommend to do a final sampling rinse with high purity water, after you….

Q:  Looking to implement an auto dispenser for our Alconox, and it is a little bit of a struggle.  Are you aware of any test equipment, or alternative methods of measuring which may be able to continuously measure the pH/conductivity at…

Q: We are currently using Alconox powder. What recommendations are there to remove Hydrated Aluminum Oxide – Al(OH)3 from aluminum?  

A: Cleaning hydrated aluminum oxide, or aluminum hydroxide, is not the best of jobs for an emulsifying alkaline cleaner like Alconox powdered detergent.
