Reducing Foam in Ultrasonic Cleaning
How do we go about reducing foam suds in our 1% Liquinox ultrasonic bath? We have 3 ultrasonic tanks in our series process. Bath 1 has the 1% solution. Bath 2 and 3 are a rinsing cascade system with RO water only. The foam is building up in tank 1 and then transfers to tank 2.

Choosing Ideal Detergent for Cleaning Metal Parts
Q. We are currently writing a protocol for conducting a process validation activity for our cleaning procedures for metal parts after our machining manufacturing process. What are the differences between cleaning effectiveness of Alconox detergent for cleaning various metallic surfaces such as stainless steel, titanium and cobalt chrome? Also, does Alconox detergent effectiveness change based on contamination characteristics, surface geometry or any other factors?
Brix vs. Conductivity: Measuring Ultrasonic Bath Concentration
Several years ago, our plant was directed to use the Refractive Index as a method of letting us monitor bath concentration during ultrasonic cleaning with your Liquinox detergent. More recently, our factory in Asia switched to Liquinox and were directed to use a conductivity measurement to monitor concentration. I decided to measure our cleaning bath using both methods and found a discrepancy — the brix (Refractive Index) reading was slightly above 1% concentration, but the Conductivity reading was nearly 2% concentration.
Cleaning Zinc Plated Metal Parts
Q. We would like to verify compatibility of zinc plated metal parts with Alconox. A. Zinc plated metal parts can be cleaned with Alconox detergent. Depending on the metal and whether there is any defect in the zinc plate coating, you can get galvanic reactions between the zinc and the underlying metal because…
