Q: Can Alconox, LLC recommend a detergent for scale removal from stainless parts in an ultrasonic? A: Sure can. The best scale removing detergent for manual cleaning of stainless steel parts is Citranox® Liquid Acid Cleaner and Detergent. Citranox detergent is a mild acid, high chelating detergent for high performance removal of metal oxides, scale, salts and inorganic residues in manual and ultrasonic cleaning. It is also corrosion inhibited and free rinsing for reliable results and no interfering residues.

Q. Is there any PFOA or PFOS in any Alconox cleaner?
A. PFOA and PFOS are perfluoro-octanoic acid and perfluoro-octane sulfonate. None of the Alconox, Inc brand cleaners contains PFOA or PFOS ingredients.

Q. Water insoluble tablet coatings used for solid dose enteric pharmaceutical tablets are very difficult to clean from coating equipment. It was hard to validate the equipment and prevent cross contamination.

Q: We are looking for detergent and process recommendations for manual cleaning of a 100 gallon mixer. We make one product in the mixer which contains water, starch, acidic buffers, sucralose and preservative. Currently when cleaning, we boil for 1 hour at 90°C, then cool, drain and soak in cool water while using the mixing blades.  Scrub brushes and a spray hosing follows that. The mixer is made from stainless steel.
