Q. We are interested in a cleaner that will perform well for mixed metal ultrasonic baths. We are cleaning titanium and cobalt chrome. What can you recommend? A. As a general rule, mixed metal baths should be avoided. When metals are far enough apart on the galvanic potential scale, batteries can form and the plating out of metal oxides can result, manifesting in dark … [Read more...] about Ultrasonic Cleaner for Mixed Metal Baths

Reducing Foam in Ultrasonic Cleaning
Q. 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. A. This type of rinsing process is very much one of our recommended rinse processes. In the … [Read more...] about Reducing Foam in Ultrasonic Cleaning
Brix vs. Conductivity: Measuring Ultrasonic Bath Concentration
Q. 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 … [Read more...] about Brix vs. Conductivity: Measuring Ultrasonic Bath Concentration
Filtering Detergent in Industrial Ultrasonic Cleaning System
Q. Is there a benefit to filtering the rinse water or the detergent solution in an ultrasonic system? Is it even advisable? If so, can you recommend a filter size (10 um??) when using Alconox detergent? This is for a new bath setup in a new piece of equipment. A. My short answer would be, it cannot hurt but filtering would likely be of limited assistance. If you are … [Read more...] about Filtering Detergent in Industrial Ultrasonic Cleaning System
Ideal pH Range for Industrial Ultrasonic Cleaning with Liquinox
Q. What is the acceptable pH range of Liquinox for effective cleaning in an ultrasonic bath? Our solution hovers around 7 and I am concerned that’s not effective. Also, does the temperature of the ultrasonic cleaning solution affect the detergent pH? A. A typical reading for Liquinox® Critical Cleaning Liquid Detergent at usage dilution is ~pH 8.5. A pH 7 reading on … [Read more...] about Ideal pH Range for Industrial Ultrasonic Cleaning with Liquinox
