How to Choose Ultrasonic Cleaning Liquid

Why Does the Cleaning Solution Affect Ultrasonic Cleaning Performance?

The cleaning solution affects:

• Surface tension — the lower, the better
• Oil removal and dissolution ability
• Stability of cavitation bubbles
• Viscosity — affects the difficulty of bubble formation
• Whether it may corrode the workpiece

Introduction to Water-Based Cleaning Solutions

Advantages

• High safety
• Better heating performance at 40–60°C
• Good removal effect for oil contamination, powder, and machining dirt
• Suitable for most metals and plastics
• Low cost and easy operation

Notes

• Water quality is affected by pH value
• Aluminum materials should not be cleaned with strong alkali
• Pure water rinsing is required after cleaning to avoid residue

Introduction to Solvent-Based Cleaning Solutions

Advantages

• Strong degreasing ability
• Fast evaporation and drying
• Suitable for parts with heavy oil contamination
• Does not leave water marks on precision parts

Notes

• Not suitable for high-temperature use
• If using an open-type system, safety and odor control must be considered
• Best used with solvent recovery and enclosed equipment

Different cleaning solutions determine the effectiveness and stability of ultrasonic cleaning.
Water-based cleaning solutions are suitable for general degreasing, cleaning powder and dust, and can be used with pure water rinsing to achieve the best cleaning and rinsing results.
The correct cleaning solution combination can improve cleaning efficiency, shorten cleaning time, and ensure that the workpiece is not damaged.
