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….
