Cleaning Carbon Steel Soot
Q: We typically clean our carbon steel with Citrajet detergent but following an unintentional overnight soak, we found a dark layer of black soot. What might this be and how should we clean it?
A: All steels that aren’t stainless will eventually get attacked by acidic solutions over time, so what you are seeing there is the action of the acids in both Citrajet® Low-Foam Liquid Acid Cleaner/Rinse (and would be the same case with its foaming sibling Citranox® Liquid Acid Cleaner and Detergent) on the carbon steel that you are using…..

Advanced Cleaning Mechanisms: What are Surfactant Systems?
Q. In your email you mentioned that Solujet and Citrajet have more sophisticated surfactant systems than a competitor’s low foaming washer detergent – could you explain a little bit more what ‘surfactant systems’ are?
A. Absolutely! Surfactants, or Surface Active Agents, are compounds that lower surface tension between particles, such as oil and water. In the oil and water example, a surfactant compound will contain hydrophilic and lipophilic molecules…
How much CIP detergent needed?
Q: We are starting a new bioprocessing facility where we will be cleaning stainless steel tanks via a Clean-In-Place sprayball system? How do I approximate how much detergent I will need?
