Low pH, or acidic, cleaners come in a number of formulations and can be helpful in several ultrasonic cleaning applications. Citrus-based cleaners clean and protect metals from the effects of chemicals. Some of the stronger low pH cleaners may damage certain materials, specifically aluminum, copper and brass. Citric acid solutions are used to passivate stainless steel and titanium by removing the free iron molecules from the surface of the metal to help prevent future corrosion such as rust.
There are several considerations when determining if or how to use solutions with your ultrasonic cleaning application. Contact us to find out which one fits better to your specific applications.
