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.

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.

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 micron) 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 would likely be of limited assistance.

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 Liquinox detergent would indicate that a notable amount of fouling has occurred from use.

Eliminating Need for Ultrasonic Bath?

Q: We are looking to replace our detergent for cutting oil removal and possibly move away from using an ultrasonic bath.  Can you help? A:  We would recommend Alconox® Powdered Precision Cleaner for removal of cutting oil from stainless parts.  It is a very strong emulsifier of oily and organic residue.  Start with a 1% solution (10 […]

Sonicating hardened tool steel

Q. We need to find an alternative cleaning solution we can use to sonicate metal (hardened steel) tools with that won’t rust them.

A. Hardened tool steel is prone to flash rusting on exposure to water and humidity with dissolved oxygen if there are no corrosion inhibitors present. You can clean tool steel in a warm Alconox solution (less than 120 deg F or less than 45 deg C) followed by an ambient temperature rinse (circa 70 deg C or 20 deg F) and a rapid …
