Ultrasonic Cleaning Detergent Bath Life

Q: We manufacture medical devices. Can we use our Alconox or Citranox bath solution more than once? How do we know that we need to change the solution?

Removing Cutting Oil, Linoleic Acid from Parts

Q: Some metalwork pieces have a residue of linoleic acid (traced back to the cutting oil) that remains after ultrasonic cleaning with Alconox® detergent. Will Alconox® will fully dissolve linoleic acid? Can you recommend a cleaning process to ensure complete removal of all linoleic acid residue from our parts?

A: Alconox® Powdered Precision Cleaner will not dissolve, but will emulsify, the linoleic acid on your machined parts. In order to get a linoleic-acid-free clean, increase

Removing PFOS and PFOA from Lab Glassware

Q. We need to remove perfluorooctanoic acid (PFOA) and perfluorooctyl sulfonate (PFOS) from laboratory glassware and stainless steel. Since they are inorganic residues, we’re using acidic cleaners, but are not finding them as effective as we expected. Any recommendations?
A. PFOS and PFOA are polar, anionic surfactants. They will best be cleaned by a high-emulsifying, anionic-surfactant-containing cleaner that can make mixed micelles to efficiently remove these residues from surfaces….
