Q. White spots appear on our stainless steel parts the day after cleaning with Alconox. Right after we clean them, they are dry and visually clean. So, is this next-day residue from the Alconox detergent? If not, can you tell us why this is happening? A. It is fairly unlikely that visually clean parts have Alconox residues suddenly appearing the next day.  In addition to Alconox being free rinsing, any residue that did not get rinsed for whatever reason, would be visible fairly immediately.

Most people in similar situations, even though the parts appear “dry and visually clean,” find that the spots are from water.

Q. How do you remove protein out of pipes, centrifuges and tanks in a CIP environment with water temperatures averaging 20C?

A. In a cooler temperature environment, consider adding an enzymatic cleaner to your alkaline/acidic CIP routine. A product like Tergazyme® Enzyme-Active Powdered Detergent, which contains both protease and surfactants, is not only efficient at removing the biofilm, but will also slow down the formation of biofilm and allow the regular cleaning cycle to clean effectively for more cycles.

Q. Does Alconox or any other recommended detergent have animal origins?

A. No. All Alconox, Inc. detergents are free-rinsing, biodegradable and contain no animal derived or genetically modified organism ingredients.
