Aqueous Cleaning With Ultrasonic Cleaners
Many industrial and professional organizations choose aqueous methods for their cleaning needs. Aqueous cleaning, particularly when combined with ultrasonics, is as effective as petroleum-based solvents – without the risks of solvent use.
Aqueous cleaning is versatile – it’s as good for delicate medical equipment as for grimy engine parts. But that versatility means that the cleaning solution must be prepared and used in the right way for each specific application.
Aqueous Cleaning with Ultrasonics
Solvents are sometimes needed to remove particularly tough contaminants from metal parts. But for most applications, ultrasonic cleaning is equally effective – and a safer, more environmentally friendly choice.
Ultrasonic aqueous cleaners use water, usually mixed with a specially designed detergent or cleaning agent. The solution is heated to an optimum temperature and ultrasound waves are applied to the ultrasonic bath.
The aqueous cleaning solution – or ultrasonic detergent – is a critical component in the cleaning process. A cleaning fluid makes contaminants easier to remove by dissolving soluble contaminants or acting as a wetting agent for insoluble contaminants. The solution is heated to accelerate and improve the cleaning process.
Troubleshooting Your Aqueous Cleaning Solution
Using the wrong concentration of cleaning fluid or the wrong temperature can impair results.
Too high a concentration or temperature may cause damage to objects and lead to higher costs. Too low a concentration or temperature may involve longer or repeated cleaning cycles and less than perfect results.
If your aqueous cleaning process isn’t producing the expected results, here are some areas to investigate.
- Are you using the right detergent at the right concentration and temperature?
Check you’re using the right chemistry for your application and the solution is maintained at the optimum temperature throughout the cleaning process.
Try experimenting within the recommended concentration and temperature ranges to find the best combination for your application. If there’s no improvement, investigate whether a different detergent may be better suited for your application.
- Are you pre-cleaning or soaking objects first?
Sometimes a short soak, pressure spray, or pre-clean with a mild cleaning solution can have a significant impact on the overall cleaning results.
- Is your cleaning solution clean enough?
You don’t want to refresh your cleaning solution unnecessarily, but you won’t achieve good results if the solution is degraded. Experiment with different refresh cycles to find the optimum time for changing the cleaning solution.
You may also need to investigate other factors in your cleaning process. Check the physical components of your cleaner, such as the pump, filter, and tank, as well as the other key factors that affect the cleaning process, such as the cleaning cycle time.
The aqueous cleaning solution that you use in your ultrasonic cleaner plays a key role in the results you can achieve from your cleaner. It’s important to follow the manufacturer’s guidance or take expert advice on how to prepare and use the cleaning solution for your aqueous cleaner.
