Cleaning Proteins: pH and Temperature
We run our caustic cleaning at pH 10-10.5. However, the specifications say the nominal pH of a 1% Tergazyme solution is 9.5 Are we compromising cleaning proteins / enzyme performance by using the higher pH and running as part of a caustic cycle? Can we run it at 110F or should we be lower?
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.
