What is the ideal temperature for cleaning ultrasonically and spray washing?
The Aqueous Cleaning Handbook, written by the technical support team at Alconox, discusses heat and cleaning applications on page 23.
In general, higher-temperature cleaning solutions result in better cleaning. In practice, there is typically an optimum temperature for a given combination of cleaning variables. Many soak, manual, and ultrasonic cleaning methods work best, for example, at 50°C to 55°C. Many spray washing techniques work best at 60°C to 70°C.
